Why does the fault persist even after replacing sensors 1 and 2?

When the scanner indicates a fault with the oxygen sensor (sensor 1 or 2) and you've already replaced them, but the code keeps appearing, it's a sign that the real cause may be before the sensor. A rich or lean mixture, a dirty throttle body, a false air intake, or even an exhaust leak before the catalytic converter can generate abnormal readings, making the new sensor appear to be the problem, when in reality it's just reporting an out-of-range condition.

The system needs retuning and a thorough check.

Sensor 1 measures the mixture before the catalytic converter, and sensor 2 verifies that the catalytic converter is functioning properly. If either sensor detects incorrect values, even if they are new, the ECU will continue to display the same code because the system is generally still out of parameters. Sometimes fuel pressures, the condition of the MAF or MAP, and even the exhaust manifold seals need to be checked. Replacing sensors without addressing the root cause is like putting air in a tire that hasn't been repaired. It may allow you to travel a few miles, but you'll end up without air again.

Steps to Measure the Resistance of a Gasoline Injector:

1. Turn off the engine and disconnect the injector.
Make sure the ignition switch is in the OFF position. Then, remove the injector connector to avoid erroneous readings due to ECU interference or residual voltage.
👉Important: Be careful with the connector lock; you must remove it by removing the safety pin.

2. Set the multimeter to the correct scale.
Set the multimeter to the resistance (Ω) scale. For injectors, use a low scale: generally 200Ω or the lowest available on your equipment.

3. Place the leads on the injector terminals.
Insert one lead into each terminal of the injector connector. It doesn't matter which lead goes on which side, as you are only measuring resistance (not polarity).

4. Read the value and compare it to the specified range.
Low-impedance injectors typically measure between 1 and 3 ohms, and high-impedance injectors between 11 and 18 ohms. If the value is outside this range or if it reads OL (open circuit), the injector is damaged.

5. Check the reading when cold.
Take the measurement with the injector at room temperature. As previously explained in Auto Avance, if you suspect the injector is failing when hot, repeat the test after using the engine (being careful not to burn yourself), as some injectors open thermally.

What is a Throttle Position Sensor (TPS)?

A Throttle Position Sensor (TPS) plays a vital role in your car’s engine management system. Its primary function is to monitor the position of the throttle valve, which controls the amount of air entering the engine. The data from the TPS is used by the Engine Control Unit (ECU) to regulate fuel delivery and ignition timing, optimizing the vehicle’s performance and ensuring smooth acceleration.

How It Works:
1. Location: The TPS is mounted on the throttle body and connected to the throttle plate.
2. Measurement: As the driver presses or releases the accelerator, the TPS measures the throttle plate’s angle.
3. Signal Transmission: The TPS sends voltage signals to the ECU, indicating the throttle’s position (closed, partially open, or fully open).
4. ECU Adjustment: The ECU adjusts fuel injection and spark timing based on the TPS data to ensure efficient engine performance.

Symptoms of a Failing TPS:
1. Jerky or delayed acceleration
2. Engine stalling or hesitation
3. Unstable idling
4. Poor fuel efficiency
5. Check engine light comes on
6. Difficulty shifting gears (in automatic transmissions)

Maintenance Tips:
• Avoid aggressive driving to reduce wear on throttle components.
• Clean the throttle body during regular maintenance.
• Address any check engine light warnings promptly to prevent further damage.

Common Diagnostic Trouble Codes (DTCs) for TPS:
• P0120: Throttle Position Sensor Circuit Malfunction
• P0121: TPS Circuit Range/Performance Problem
• P0122: TPS Circuit Low Input
• P0123: TPS Circuit High Input
• P2135: Throttle/Pedal Position Sensor/Switch A/B Voltage Correlation

A malfunctioning TPS can result in poor vehicle performance and even cause unsafe driving conditions. Regular diagnostics and timely repairs are essential to keeping your vehicle running smoothly.

MAP (Manifold Absolute Pressure),
MAF (Mass Air Flow) and CKP (Crankshaft Position) sensors are key parts for your vehicle to perform well. Keeping them clean and in good condition ensures that the engine runs efficiently and accurately. Here I explain how they impact performance:

Sensor MAP (Manifold Absolute Pressure):

The MAP sensor measures the absolute pressure within the intake multiple and sends this information to the ECU (Electronic Control Unit). Based on this reading, the ECU calculates the engine load and adjusts the amount of fuel injected and the time of ignition.

Technical function: Operates using a piezoelectric element that generates a voltage proportional to the measured pressure. When the engine is in slow motion, the pressure on the multiple is low (elevated vacuum), and at full charge, the pressure approaches the atmosphere.
Common Problems: A dirty or defective MAP sensor can cause improper air-fuel mix, leading to loss of power, increased fuel consumption, or difficulty starting.

Sensor MAF (Mass Air Flow):

The MAF sensor measures the mass of air entering the engine in real time, essential information to calculate the ideal air-fuel mix.

Technical feature: Use a hot wire or heat film. When air passes through the sensor, it cools the meter element, which changes its resistance. The ECU interprets this change to determine the amount of air.

Common Problems: Dirt in the MAF sensor can isolate the thermal element, reducing sensitivity. This results in error readings that affect combustion, causing ignition failures, acceleration problems, and improper mixing.

Sensor CKP (Crankshaft Position):

The CKP sensor detects the angle position and rotation speed of the crank. Provides a critical signal for ignition synchronization and fuel injection.

Technical Function: Usually it is a Hall effect sensor or inductive. The stork has a gear with teeth (flare wheel) that passes in front of the sensor. Each tooth generates a pulse signal that the ECU uses to calculate the exact position of the stork.

Common Problems: If the sensor is dirty, it can interfere with accurate pulse detection. This causes ignition failures, loss of power, difficulty starting or even engine not starting.

Sometimes, the issue isn’t the oil itself but the oil pressure sensor giving false readings. If the sensor malfunctions, it may indicate low oil pressure when the oil is fine.
- Fix: Have the oil pressure sensor tested and replace it if necessary.

5. Clogged Oil Filter
A clogged oil filter can restrict the flow of oil, resulting in low oil pressure. This often happens if you skip oil changes or use poor-quality oil.
- Fix: Change the oil filter at each oil change. Always use the manufacturer-recommended filter for optimal performance.

6. Engine Wear
Excessive engine wear, especially in components like bearings, can cause oil to flow too easily, leading to low oil pressure.
- Fix: Regular maintenance, including replacing worn parts, can prevent this issue. In severe cases, a complete engine rebuild may be necessary.

7. Leaky or Damaged Oil Lines
Cracks or leaks in the oil lines can cause oil to escape, reducing the pressure.
- Fix: Inspect oil lines for leaks or damage and replace any compromised components.

8. Thinner Oil Than Recommended
Using oil that’s too thin for your engine can result in low oil pressure, especially in hot weather or under high-performance conditions.
- Fix: Always use the correct oil grade specified by your car’s manufacturer.

How to Address Low Oil Pressure:
Step 1: Check the oil level and top it up if needed.
Step 2: Inspect for leaks, and address them promptly.
Step 3: Change the oil and filter regularly.

THROTTLE POSITION SENSOR (TPS): A CRUCIAL COMPONENT FOR ENGINE PERFORMANCE :

Remember that your car’s engine requires a precise amount and ratio of air and fuel mixture as input for optimal combustion to take place inside its internal combustion chamber. In short, incorrect amounts of air and fuel mean problems for the engine. While the throttle position sensor makes sure the engine gets the correct amount of air, it is common for it to malfunction. Learn bad throttle position sensor symptoms now so that you can take care of this engine problem as soon as it arises.

WORKING PRINCIPLE OF THE THROTTLE POSITION SENSOR:

This sensor is usually mounted on the throttle body. It senses the position of the throttle valve or butterfly valve and transmits the information to the Engine control unit. This sensor monitors how far down the accelerometer pedal is pushed and gives the output current determining the position of the pedal. The position of the pedal controls the airflow of the engine. If the valve is wide opened, a large amount of air is supplied to the engine and vice-versa. The output given by this sensor, along with other sensors is transmitted to the engine control unit, which decides the amount of fuel to be injected into the engine accordingly.

This sensor is a three wired potentiometer. Through the first wire, a 5V power is supplied to the sensors resistive layer. The second wire is used as ground whereas the third wire is connected to the potentiometer wiper and provides input to the Engine control system.

Based on its construction, there are three types of throttle position sensors. They are the throttle position sensors with built-in end switches also known as Closed Throttle Position Sensor, the potentiometer type and the combination of both these types.

A throttle position sensor consists of mechanical parts that may become worn and require replacement. A malfunctioning throttle position sensor will relay wrong data to your car’s computer.

A faulty throttle position sensor should not be ignored. When your engine is not receiving the correct air-fuel ratio for proper function, it is working below optimal efficiency. The result is inevitably lower fuel economy and will cause damage to your engine, reducing its lifespan.

To determine the exact amount of air needed for the engine at any specific time, the car’s computer, known as the Power Control Module, collects data continuously, as much as many times per second, including air mass flow, engine RPM, air temperature, the position of the throttle butterfly valve, and how fast the valve’s position sensor changes.

If the throttle position sensor and other sensors work well, your car will maintain optimal fuel economy and smooth handling. In other words, the engine will effectively receive the optimal fuel and air input to accelerate, coast, and cruise smoothly.

THE APPLICATIONS OF A THROTTLE POSITION SENSOR :

🔧This sensor gives the engine control unit information about the position of the butterfly valve. It is used to detect the Idle position, Wide Open Throttle state of the valve. When in valve is in Idle state the output voltage of the sensor is below 0.7V. When the full load state is detected the output voltage of the sensor is about 4.5V.

🔧Damage of the Throttle Position Sensor leads to flashing of Check Engine signal. When this sensor is malfunctioned, the computer could not determine the position of the valve correctly which leads to surge or stalling of the vehicle. What are the three states of throttle value the sensor can detect?

WHAT HAPPENS IF YOUR THROTTLE POSITION SENSOR IS FAULTY?

🔧The throttle position sensor can gradually fail or all at once. It can be faulty due to many causes.

🔧In most situations, when there is an issue with the throttle position sensor, the Check Engine Light will turn on. Additionally, most carmakers supply a “limp home” mode of operation with decreased power if there is a failure in your engine. This is made to enable a driver to get off a crowded highway in a safer way.

🔧When the throttle position sensor is faulty, your engine is not receiving the optimal amount of fuel, thus it is not working at optimal efficiency. Remember that your engine is the utmost complex and delicate component, which requires every single part to work in perfect harmony and with precision. A tiny deviation in any element will reduce its efficiency, or even cause damage and shrink its lifespan.

🔧Below optimal efficiency means poor fuel economy. This will be one of the most noticeable throttle position sensor symptoms you will encounter with a faulty sensor.

CAN YOU DRIVE WITH A BAD THROTTLE POSITION SENSOR?

🔧Technically you can still drive with a bad throttle position sensor. However, do note that a bad throttle position sensor can cause an inability to shift up, rough or slow idle, and a lack of power when accelerating.

🔧Driving with these symptoms will put you and other drivers around you in danger, so you should bring your car to a mechanic as soon as possible..

HOW LONG DO TPS SENSORS LAST?

🔧The batteries in the TPS sensors are made to last 5 years. They are built into the sensor so they can not be replaced like those of a flashlight.

🔧Hence, it is recommended by car manufacturers to replace TPS sensors every 5 years to enjoy safe and hassle-free driving. Do not leave it until you’re encountering faulty throttle position sensor symptoms.

🔧Bad throttle position sensor symptoms
Below are the most common symptoms of a bad throttle position sensor. Address throttle position sensor problems as soon as possible to avoid the risks of accidents and damaging your delicate engine.

SYMPTOMS OF A BAD THROTTLE POSITION SENSOR:

1. CHECK ENGINE WARNING LIGHT:

One of the first bad throttle position sensor symptoms is the Check Engine Light will flash on your dashboard to warn you when any sensor goes bad. If the Check Engine Light is turned on, pay attention to any other strange signals and troubleshoot as soon as possible before the issue gets worse.

2. POOR FUEL ECONOMY:

As mentioned above, due to the engine’s inefficiency, poor fuel economy will be one of the inevitable bad throttle position sensor symptoms. The throttle position sensor works alongside other sensors to ensure the engine gets everything it needs to run smoothly.
When these sensors start to go bad, your car’s computer receives incorrect data, leading to your engine getting incorrect inputs. Different parts try to overcompensate for these deviations.
For instance, if the engine is receiving more air than it needs, the computer will compensate by injecting extra fuel to rebalance the air-fuel mixture. Therefore, in most cases when your sensor goes bad, your car will be noticeably consuming more fuel than usual.

3. ENGINE ROUGH IDLING OR SUDDEN STALLING:

Faulty throttle position sensors can cause rough idling due to fluctuating airflow. If you see your car misfiring, idling rough, or stalling out while you drive, it is highly likely that you have a faulty throttle position sensor.

4. STARTUP AND ACCELERATION ISSUES:

Also due to fluctuating airflow, a bad throttle position sensor may cause all sorts of power issues. Your engine may start up but it will have little to no power, run briefly, but then die out.
Otherwise, it can also cause your car to have spontaneous surges during accelerations for no apparent reason, or cause weaker accelerations than usual.

5. ABRUPT BUCKING OR JERKING:

The throttle position sensor sometimes fails in a way that causes the signal sent to the engine’s computer to be sporadic. The effect will be similar to when you are quickly applying and releasing the gas pedal.

6. DIFFICULTY in SWITCHING GEARS:

If the throttle position sensor fails it can cause automatic transmission shifting problems. The throttle position sensor is important for proper automatic transmission control because it immediately establishes the driver’s intent, and transfers this information to the Transmission Control Module.
Without such correct and timely transfer of data, you will experience delay and/or difficulty in switching gears.

7. YOUR CAR GOES INTO LIMP-HOME MODE:

In some models, a failing or faulty throttle position sensor can cause the engine to go into “limp-home mode”. In this situation, you will experience reduced engine power, and you may be stuck in a higher gear.
This is a safety feature designed to get you off the highway and allow you to drive a few extra miles to the nearest repair shop. Once this happens, do not drive any more than needed and get repairs immediately.

HOW TO REPAIR A THROTTLE POSITION SENSOR

QUICK CHECK ✔️

✔️Once you’ve established the issue is with your sensor, check if the problems could be the result of faulty or loose wiring. Just like any other electrical wiring, your throttle position sensor is susceptible to corrosion and faulty connections.

✔️Check the wiring and connection points before moving on the reprogramming or replacing the sensor. Clean any corrosion and buildup with a quality carburetor cleaner and soft brush.

✔️First, locate the throttle position sensor. It should be mounted to your throttle body, which is on top of your engine.
The throttle position sensor is a small sensor that’s about the size of your key fob. It has an electrical connector attached to it that normally houses three wires. On most engines, there are two smaller screws that secure it to the throttle body.
Once you’re aware of bad throttle position sensor symptoms and have performed the above quick check, you can choose to have a professional check it out and replace the faulty sensor.
While completely replacing your sensor may be the best way to avoid future issues, some issues can be easily fixed by reprogramming or repairing your sensor. This step can also be necessary when you install a new sensor. Learn this handy maintenance tip to save yourself time and trouble going to the mechanics.

RESETTING THE THROTTLE POSITION SENSOR

Resetting is sometimes all that is required to get rid of throttle position sensor symptoms and restore your sensor to proper function. The easiest way to reprogram or reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your Engine Control Module.

This is important, as it helps you avoid the risk of electrical shock or causing an error code on your Engine Control Module.
Don’t attempt this if you’re uncomfortable working with electricity, as removing the wrong fuse or cable from your battery could be dangerous. Sometimes, you’ll need professional software to reprogram your sensor. In this case, this task is best done by a professional mechanic.
Otherwise, sometimes your sensor is irreparably damaged. It needs to be replaced in order to restore your engine to its optimal efficiency.

HOW TO REPLACE A THROTTLE POSITION SENSOR

REMOVE THE SENSOR:

🔧While removing the faulty sensor, take careful note of where each part and component is, so that you will be able to reassemble the new sensor easily later on.

🔧First, disconnect your negative battery cable before removing the sensor. This helps you avoid the risk of electrical shock or causing an error code on your Engine Control Module. Your throttle position sensor should be attached using electrical connectors. These connectors are easy to remove using the tab on the side.

🔧Once the electrical connectors are removed, look for the mounting screws on your sensor. Carefully unscrew and remove your throttle position sensor.

INSTALL THE NEW SENSOR:

🔧To make sure you buy the correct replacement sensor for your vehicle, consult your owner’s manual when shopping for a new one.

🔧Install your new sensor by repeating the removal steps backward. Start by installing the sensor using the mounting screws. Then, connect your sensor to your vehicle’s electrical system using a convenient electrical connector. You should be able to easily push it together and hear a distinct click. Check to ensure a firm connection.

🔧Connect your battery and now check if the replacement works. Start your car and test the idle and acceleration to see if the previous starting, idling and acceleration problems are resolved. Your car should idle smoothly and accelerate with adequate power.

Depending on your vehicle and the sensor you’ve installed, you may need to manually adjust the sensor. Other options allow automatic adjustments

IN CONCLUSION:

the throttle position sensor (TPS) is a crucial component in fuel-injected engines, providing vital information about the throttle position to the engine control unit (ECU). Its accurate readings enable precise control over fuel injection, ignition timing, and other engine parameters, resulting in optimal engine performance. Understanding the TPS and its functions, along with proper maintenance and troubleshooting techniques, is essential for ensuring the smooth operation of the vehicle's engine.
