Is measure voltage within Specification?
YES

Go to "SIGNAL CIRCUIT INSPECTION " procedure.

NO
- Open circuit or short circuit to chassis ground between TPS harness connector and reference voltage.
- Open circuit or short circuit to chassis ground between TPS harness connector and PCM 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 2 is 0 V.
  - Possible cause: Open or short between terminal 32 of PCM and Terminal 2 of TPS
