TEST
3 Measure the voltage on the (K44) CMP Sensor Signal circuit at the CMP Sensor
harness connector.
Is the voltage between 4.5 and 5.0 volts?
Yes → Go To 4
→ Go To 6
No
4 Turn the Ignition off.
Disconnect the PCM harness connectors.
Measure the resistance of the (K900) Sensor ground circuit from the CMP Sensor
harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 5
→ Repair the open in the (K900) Sensor ground circuit.
No
5 NOTE: Inspect the Camshaft sprocket for damage per the Service Informa-
tion. If a problem is found repair as necessary.
If there are no possible causes remaining, view repair.
Repair
6 Turn the ignition off.
Disconnect the PCM harness connectors.
Ignition on, engine not running.
Measure the voltage on the (K44) CMP Sensor Signal circuit at the CMP Sensor
harness connector.
Is the voltage above 5.2 volts?
Yes → Repair the short to voltage in the (K44) CMP Sensor Signal
→ Go To 7
No
7 Turn the ignition off.
Measure the resistance of the (K44) CMP Sensor Signal circuit from the CMP Sensor
harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 8
→ Repair the open in the (K44) CMP Sensor Signal circuit.
No
8 Measure the resistance between ground and the (K44) CMP Sensor Signal circuit at
the CMP Sensor harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K44) CMP Sensor Signal
→ Go To 9
No
