knock sensors

[reaper ws6]

i got a code that pops up goes away and then pops back on again is p0332 i believe. My knock sensors Now i am running a cam and the engine does rock back and forward im guessing because of the cam could my cam be making this code pop up or is it something else? i dont really hear my engine knocking just a small ticking like the lifters. the oil pressure is normal, and my fuel pressure some times wen cold my fuel gauge located at the fuel rail reads zero, i dont know if thats normal.

thanks for the help

It reads zero when off? Did you check the motor mounts, the cam might cause a little more motion but it shouldn't be rocking around violently. Also was the car tuned for the cam?

naw is not violently and yes its been dyno tune and it only reads zero some times not all the time

When you did the cam did you replace the knock sensors? The harness could also be a cause of it. If you havent changed these i suggest replacing them with new ones and a new harness.

is that what the code means? p0332 is it bad to run the car like that? i mean it drives really good with no problem

Well it's just pulling timing. A bad knock sensor can cause a car to lose lots of power, i really recommend swapping out sensors. The sensor is just for bank 2 but if the sensors have never been replaced i would swap them both out along with the harness, it's just good insurance. New ACDelco Replacements is the only way i would go though. Have had really bad luck with aftermarket brands

Here are the part numbers if you end up doing it
Knock Sensor - 12589867
Harness - 12601822

ok thanks i kinda got a felling that if i swap them out there still going to come on. But im thinking on doing the lsxr intake and if i do it ill replace everything will im at it and take her for another dyno tune
