Signal Circuit Inspection

Check for short to ground in harness.
1. Ignition "OFF".
2. Disconnect TP sensor connector and PCM connector.
3. Measure resistance between terminal 3 of TP sensor harness connector and chassis ground.
  Specification: Infinite

4. Is the measured resistance within specifications?
  YES
  - Go to " 2 Check for open in harness" as below.
  NO
  - Check for short to ground in harness.
  - Repair or replace as necessary. And then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
