Signal Circuit Inspection

Check short to ground in harness
1. IG "OFF" and disconnect TPS connector and PCM connector.
2. Measure resistance between terminal 6 of TPS harness connector and chassis ground.
3. Measure resistance between terminals 6 and 5 (8) of TPS harness connector.
  Specification: Infinite
4. Is the measured resistance within specification?
  YES
  - Go to " 2Check open in harness" as follows
  NO
  - Repair short to ground in harness, and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check open in harness
1. IG "OFF" and disconnect TPS connector and PCM connector.
2. Measure resistance between terminal 6 of TPS harness connector and terminal 57 of PCM harness connector.
  Specification: Below 1Ω
3. Is the measured resistance within specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Repair open in harness, and go to " VERIFICATION OF VEHICLE REPAIR " procedure.
