Check for open in signal harness.
1. Ignition "OFF".
2. Disconnect PCM connector.
3. Measure resistance between terminals 3 of sensor harness connector and 10 of the PCM harness connector.
  Specification: Approx. 0Ω
4. Is resistance within the specification?
  YES
  - Go to next step as below
  NO
  - Check for an open in signal harness. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check for short to ground in signal harness.
1. Measure resistance between terminal 3 of sensor harness connector and chassis ground.
  Specification: Infinite
2. Is resistance within the specification?
YES
- Go to "COMPONENT INSPECTION " procedure,
NO
- Check for short to ground in signal harness. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
