P0118-ECT SENSOR VOLTAGE TOO HIGH —
TEST
3 Turn the ignition off.
Disconnect the ECT harness connector.
Connect a jumper wire between the (K2) ECT Sensor Signal circuit and the (K4)
Sensor ground circuit in the ECT harness connector.
Turn the ignition on.
With the DRBIII , read ECT voltage.
Is the voltage below 1.0 volt?
Yes → Replace the ECT Sensor.
→ Go To 4
No
4 Turn the ignition off.
Disconnect the ECT Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the (K2) ECT Sensor Signal circuit between the ECT
Sensor harness connector and the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 5
→ Repair the open in the (K2) ECT Sensor Signal circuit.
No
5 Turn the ignition off.
Disconnect the ECT Sensor harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the (K4) Sensor ground circuit between the ECT Sensor
harness connector and the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 6
→ Repair the open in the (K4) Sensor ground circuit.
No
6 NOTE: Before Continuing: Disconnect the PCM harness connector and
check the related wiring terminals for corrosion, damage or terminal push
out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay
particular attention to all Power and Ground circuits.
If there are no possible causes remaining, view repair.
