Hello all. Hope I'm in the right place for this.
I have a 2002 Grand Prix GT 3800. P0332 (rear knock sensor low output) set. No driveability issues expect occasional rough idle at start up. Previous owner said she replaced "the" knock sensor, don't know which one, or if she really did. Got a look at it today, someone has replaced the pigtail harness at some point. I have a new sensor and harness, but before I replace it (it looks like a ***** to do) I want to check continuity of the wire between pcm and sensor, possibly run a new wire if needed. does anyone have excess to a pin out diagram of the pcm? like which pin on which connector is knock sensor 2 at the pcm? Im not having luck finding it. Thanks for any help.
