Signal Circuit Inspection

  1. Check open in harness
    1. IG "OFF" and disconnect knock sensor connector and PCM connector.
    2. Measure resistance between terminal 1 of knock sensor harness connector and terminal 54 of PCM harness connector(C144-B).
    3. Measure resistance between terminal 2 of knock sensor harness connector and terminal 53 of PCM harness connector(C144-B).

      Specification; Below 1Ω

    4. Is the measured resistance within specification?

      YES 

      • If the problem is corrected after substituting with a known - good knock sensor, replace it. If the problem is pending, check for proper operating after substituting with a known - good PCM. and then if the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO 

    NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function before reusing the PCM
