take it to the parts store and see if they can erase the code and reset the computer for you.. it may work..

Ther is a sensor on the rear end. Take kit out and clean it. This should solve your problem. Located on top of the bell housing

Hi!!
The Knock Sensor is located on the right side of the engine block, right below the exhaust manifold. See #7 on picture below:


Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

That code is for your knock sensor which is located under your intake manifold. There are two under the intake. I would recommend replacing both, they are 40 dollars a piece usually plus the labor to remove the intake.

Possible bad engine crank sensor. Electronic Control Module provides initial timing for start then depends on the crank sensor once started for timing and firing

Bad news is your knock sensor is under the intake manifold. The good news is this is a fairly easy fix as far as removing the intake goes. I assume you have the 5.3 engine? In the many cases where i have replaced the little sensors the best thing to do is replace them both while you are under there along with the harness that connects them to wiring on top of the engine and put a dam of silicone around the sensor boot so that they dont go bad again because the main cause of failure for these sensors is water intrusion into the little hole in the intake valley where they reside. Thanks for using fixya!! best of luck!!
