MIL on: code 23
 

Hi Guys,

Any idea? What can cause this??

I jumper the ECU to check the codes and it showing code 23

Knock sensor circuit malfunction.

Car has just got the clutch replaced.

Any idea how to fix?

Car runs fine ... the codes comeback after I reset the ECU... as instructed by the service manual...

Followed the ECM idle learning procedure...after several seconds on holding the rev at 3000rpm the MIL comes back on...
