7 Turn the ignition off.
Disconnect the Camshaft Position Sensor harness connector.
Disconnect the Powertrain Control Module harness connectors.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between the Camshaft Position Sensor signal circuit and the
sensor ground circuit at the Camshaft Position Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes → Repair the Camshaft Position Sensor signal circuit for a short to
→ Go To 8
No
8 If there are no possible causes remaining, view repair.

9 Turn the ignition off.
Disconnect the Camshaft Position Sensor harness connector.
Disconnect the Powertrain Control Module harness connector.
Measure the resistance of the 8 volt supply circuit from the CMP Sensor harness
connector to the PCM harness connector.
Is the resistance below 5.0 ohms.
Yes → Go To 10
→ Repair the 8 volt supply circuit for an open.
No
10 Turn the ignition off.
Disconnect the Camshaft Position Sensor harness connector.
Measure the resistance of the 8 volt supply circuit at the CmP sensor harness
connector to ground.
Is the resistance below 5.0 ohms?
Yes → Repair the 8 volt supply circuit for a short to ground.
→ Go To 11
No
11 Turn the ignition off.
Disconnect the Camshaft Position Sensor harness connector.
Measure the resistance between the 8 volt supply circuit and the CMP signal circuit
at the CMP sensor harness connector.
Is the resistance below 5.0 ohms?
Yes → Repair the 8 volt supply circuit for a short to the CMP signal
→ Go To 12
No
