When Monitored:
With the engine cranking or running
•
Set Condition:
The Engine Control Module (ECM) does not receive a signal from the Crankshaft Position Sensor when the
Camshaft Position Sensor indicates engine rpm.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Diagnostic Test
1.
VERIFY ACTIVE DTC
NOTE: If DTC P0652 or P0653 is present with this DTC, diagnose DTCs P0652 or P0653 before diagnosing
this DTC.
NOTE: The Timing Belt/Chain must be correctly installed and operational before diagnosis can be made.
Refer to the Service Information to ensure the timing belt is properly installed.
NOTE: If the ECM detects and stores a DTC, the ECM also stores the engine/vehicle operating conditions
under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the
DTC is displayed.
NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may
assist when checking for an active DTC.
Turn the ignition on.
With the scan tool, erase the ECM DTCs.
Attempt to start the engine cranking the engine for at least 7 seconds.
With the scan tool, read the ECM DTCs.
Does the scan tool display this DTC?
Yes
>> Go To 3
No
>> Go To 2
