Hey guys, as the title says I get a CEL that stays on only if I turn/corner hard. This has only happened recently after I got my car back from the mechanic after getting my clutch replaced with the Exedy Heavy Duty clutch. It stays on when the car is on, but when I turn it off and turn it on again the CEL doesn't turn on unless I turn/corner heavy. My question is what could be causing the CEL to turn on? I went back to the mechanic and he said to come back on Monday but I just want to get an idea of what could be the problem. I've used the search function but none came up with my problems..

(Car is a 1999, with 135000km's on it)

Thanks.

No point in guessing, just pull the code. The knock sensor probably broke trying to remove the upper starter bolt.

If its got code P0325, ^ he is correct.

That would be my guess also.

Thanks guys, guess I'll wait until Monday

So I just checked and the code came out as 23-01 knock sensor? But ive searched around and isnt the code p0325? I'm new to this stuff and kind of confused.

Thats a blink code, same thing as P0325.

The original reply is 100% correct, the knock sensor was broken by the extension while accessing the upper starter bolt. This bolt threads into the transmission so it must be removed.

If anyone does an s2k clutch job and doesnt have prior knowledge of the knock sensors position or how delicate it is, it is almost inevitable that it will get broken. Sad to say this is very common. Pretty much any thread that has CEL and clutch in it, you'll find a broken knock sensor.

So you need a new one.

Remove the serp belt, serp belt tensioner, the black front intake bracket with the four bolts, and the aluminum mounting block behind the belt tensioner. Use an open end wrench to remove, and install the knock sensor.


This is the safest way to replace it. if you try to feel around with a socket or try to replace it by any other means, you will certainly break the new one also. All you need to do it put light pressure on the connector and it breaks instantly.

Trust me on this. if your going to bring it back to the mechanic, print this.

Cheers. Yeah I'll be getting the mechanic to replace it since it was his fault. Thanks for the input
