2000 Gp Gt Dtc

[dill_roy]

I have a 2000 Grand Prix GT with a 3.8 @ 106k miles. my check engine light came on over a month ago and it read p0327, o2sensor bank1 low signal, p0332, and p0336. well, it got to the point that it wanted to stall ; so i got the crankshaft position sensor replaced (p0336) thinking that would clear out p0332 and p0327 but now the light is back on! so i'm getting ready to do the plugs and wires which it needed anyway. any suggestions on these knock sensor codes? or am i on the right track?

So is it safe to say the stalling issue has been resolved? Did the P0332 and P0327 DTCs return since the SES/CEL light is now on?

Those knock sensor 1 and 2 DTCs are basically wiring faults or low output voltage amplitude. So check the wiring harnesses and electrical connectors. Also, check the PCM 5 volt reference signal at the input of each knock sensor.

Yeah i think the stalling issue was resolved with the crankshaft position sensor. i will post back as soon as i can get those codes that reappeared. I'm currently also dealing with a clamp that came off of the CV boot. I'm gonna take it across town and have it filled back up with grease and clamp replaced. since i noticed it right away and only drove like that a couple miles the Joint should still be ok.
