  1. Check for open in signal circuit.
    1. Ignition "OFF"
    2. Measure resistance between terminals 2 of the OTS harness connector and 52 of the PCM harness connector.

      Specification: Approx. 0Ω

    3. Is resistance within specification?

      YES: 

      • Go to next step below.

      NO: 

  2. Check for short to battery in signal circuit.
    1. Disconnected PCM connector.
    2. Ignition "ON" & Engine "OFF".
    3. Measure voltage between terminals 2 of the OTS harness connector and 52 of the PCM harness connector.

      Specification: Approx. 0V

    4. Is voltage within specification?

      YES: 

      NO:
