NOTE: The conditions that set the DTC are not present at this time. The
following list may help in identifying the intermittent condition.
With the engine running at normal operating temperature, monitor the DRB
parameters related to the DTC while wiggling the wiring harness. Look for param-
eter values to change and/or a DTC to set.
Review the DTC When Monitored and Set Conditions. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.

No → Test Complete.
3 Refer to the Service Information to ensure the Engine Drive Gears/Sprocket are
installed correctly and the camshaft and crankshaft gears are timed correctly.
Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Disconnect the ECM harness connectors.
Measure the resistance between ground and both of the CKP Sensor Signal circuits.
Is the resistance above 1000 ohms for both measurements?
All
Yes → Go To 4
No → Repair the CKP Sensor Signal circuit(s) for a short to ground.
Perform ROAD TEST VERIFICATION - VER-2.
4 Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Disconnect the ECM harness connectors.
Measure the resistance between the CKP Sensor Signal circuits.
Is the resistance above 1000 ohms?
All
Yes → Go To 5
No → Repair the CKP Sensor Signal circuits for a short together.
Perform ROAD TEST VERIFICATION - VER-2.
5 Turn the ignition off.
Disconnect the CKP Sensor harness connector.
Disconnect the ECM harness connectors.
Measure the resistance of CKP Sensor Signal circuits.
Is the resistance below 10.0 ohms for both measurements?
All
Yes → Go To 6
No → Repair the CKP Sensor Signal circuit(s) for an open.
Perform ROAD TEST VERIFICATION - VER-2.
