    I'm helping a nieghbor track down why his Knk Sensor code P0332 wont clear.
    We replaced both sens 1 and sens 2 because they are cheap. Didn't fix it. Found a grd wire broken in the harness and sens 2 wire damaged. Repaired both those. Didn't fix it.
    Pulled PCM conn 2 did a voltage change on pins 6,7,8,9. Which are the wires for the knk sensors. 2.38 for the 5v ref voltage on both 7 and 9 (gry wires), 2.38 signal voltage on both 6 and 8 (l-blu and dk-blu).
    Engine sound fine, no discernable knock. Anyone have a clue. Don't want to dump the car. It's in good shape and still gets used regularly. But I gotta smog it to register it.
