Mazda Demio knock sensor.
One of todays jobs was a Mazda Demio which had an engine light that would come on and go off, come on and go off. Connected the scan tool and found a code stored for the engines knock sensor. Quite a common issue on these engines. Best part about this job is it's located directly behind the intake manifold. So off with intake, replace the sensor and wack the manifold back on. Cleared the codes and shes all good to go!
