knock sensor


Senior Member
does anyone have any pictures of a knock sensor taken out of the engine ?

also does anyone know if when the knock sensor is throwing a code does it limit the engine's performance in anyway?

It throws the ECU in open loop, which gives you retarded timing, richer a/f mixture, and ultimately less performance.

quick way to check the sensor. hook up and check your timing, use a hammer and tap the block as your reading the timing. if the timing retards as your tapping then its working just fine.
