DTC 118 Engine Coolant Temperature (ECT) or 113 Intake Air Temperature (IAT) indicates that the corresponding sensor signal is greater than the Self-Test maximum. The maximum for ECT and IAT sensors is 4.6 volts.

Possible causes:
- Open in harness (IAT or ECT).

- Faulty connection.

- Faulty sensor.

- Faulty Powertrain Control Module (PCM).

- Key "OFF".

- Disconnect suspect temperature sensor.

- Connect a jumper wire between the sensor signal circuit and SIG RTN circuit at the temperature sensor vehicle harness connector.

- Run Key On Engine Off Self-Test.

- Is Diagnostic Trouble Code (DTC) 112 or 117 present?

Yes -- Replace suspect sensor. Remove jumper wire. Reconnect vehicle harness. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
