Is measure voltage or resistance within Specification?
YES
- Go to "COMPONENT INSPECTION " procedure.
NO
- Open circuit between TPS harness connector and PCM harness connector.
- Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NOTE:
  In case, when the TPS connector is disconnected, the voltage of TPS terminal 3 is infinite.
  - Possible cause: Open circuit between terminal 17 of PCM and Terminal 3 of TPS
