2000 Gp Gt Dtc

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 :frown: ; so i got the crankshaft position sensor replaced (p0336) thinking that would clear out p0332 and p0327 but now the light is back on! :banghead: 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.
