What would happen if you tried to start your engine without the knock sensor plugged in? Let me know thanks..

 

When knocking occurs, the weight in the cylinder case moves, causing the piezo electric element in the KS to translate the vibration into an electric voltage. A signal is then transmitted from the KS to the ECU. In response, the control unit retards spark timing to prevent engine knocking.

 

It would throw a CEL about 50 feet down the road. Other than that, nothing.

 

trying to figure out whats wrong..
had head all re done , new valves, seals, springs, etc.. neways got it all back together. when i try n start it, it backfires..
only thing i know thats not on is the knock sensor. i didnt think itd matter right now..
Only other thing i can think of is that when i set the timing that i have the TDC set on the exaust stroke not the intake stroke? what do u guys think?
Going to check the disp cap tomorrow. make sure the lil rotor isnt broke or nething, let me know thanks

 

Recheck the cam and ignition timing. A knock sensor out of place would not cause a backfiring, but you should put it in anyway to get rid of the check engine light.

 

ignition timing hasnt changed. and timin marks seem to b linged up might b off 1 tooth..

 

if its backfiring sounds like the engine timing is off

 

it turns over fine, got fuel n everything when it kicks (tries to start) it backfires, even some flame out the throttle body.. any suggestions
