Signal Circuit Inspection

Check voltage
1. IG "OFF" and disconnect TPS connector.
2. IG "ON" and ENG "OFF"
3. Measure voltage between terminal 6 of TPS harness connector and chassis ground.
  Specification: Approx. 0V
4. Is the measured voltage within specification?
  YES
  - Go to "GROUND CIRCUIT INSPECTION " procedure.
  NO
  - Go to step 2.
Check short to battery in harness
1. IG "OFF" and disconnect TPS connector and PCM connector.
2. Measure resistance between terminals 1 and 6 of TPS harness connector.
3. Measure resistance between terminals 4 and 6 of TPS harness connector.
4. Measure resistance between terminals 2 and 6 of TPS harness connector.
5. Measure resistance between terminals 3 and 6 of TPS harness connector.
  Specification: Infinite
6. Is the measured resistance within specification?
  YES
  - Go to "GROUND CIRCUIT INSPECTION " procedure.
  NO
  - Repair short to battery in harness, and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
