That check-engine light is trying to tell you something.
What it isn’t doing is handing you a repair estimate.
Modern vehicles monitor dozens of systems, and a diagnostic trouble code is only one piece of information. The same symptom can sometimes have several possible causes.
That’s why simply reading a code and replacing a part can become an expensive guessing game.
Proper diagnostics goes further.
A technician uses the information from the vehicle along with testing, inspection and experience to determine what is actually causing the problem.
At All Terrain Auto Care, our goal is to diagnose first and repair second.
We want you to understand what we found, why we’re recommending a repair and what your options are before money is spent replacing parts.
That means clearer information and a better repair decision. We repair most makes and models including: Ford, Dodge, Ram, Chevrolet, Toyota, Honda, Nissan, Subaru and more! Your vehicle is in good hands with a shop your friends and neighbors have trusted for decades in the Knoxville area.
Serving Knoxville for over 26 years.
Check-engine light on? Let’s find out why.
