im having a broken knock sensor, but the CEL didnt throw any code...anybody know why?
please help..

 

Does your CEL light come on when you turn the key to 'on' initially? If not, your bulb's probably blown.

 

Stock or chipped ecu?and like mentioned above does your cel come on when you turn the key?

 

Year and make of car would help along with what engine you have

 

Yes, the CEL come on when i turn the key on, and go off after 2-3sec.
currently using P13 MINES ecu. my car is 92-95 civic.

 

Program probably has knock disabled

 

do you mean that my MINES ecu doesn't need the knock sensor?

 

Yes

 

ok thanks for the info......but something strange happen today, i tried to unplug some socket like MAP,TPS, vtec solenoid and fan switch the CEL also didnt throw any code at all.........later i tried off the ignition. with unplug some sensor socket, i turn ON the key CEL light up 2-3sec and go off, the CEL again didnt throw any code.
