Diagnostic Aids
* With this DTC set, the engine may crank for an extended period of time during start-up.
* This test procedure requires that the vehicle battery has passed a load test and is completely charged. Refer to Battery Inspection/Test (See:
Starting and Charging/Testing and Inspection/Component Tests and General Diagnostics/Battery Inspection/Test).

Circuit/System Verification
1. Engine idling, observe the scan tool Crankshaft Position Active Counter parameter. The parameter should be incrementing.
2. Engine idling, observe the DTC information with a scan tool. DTC P0336 should not set.
3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not set. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
Note: You must perform the Circuit/System Verification before proceeding with Circuit/System Testing.
1. Ignition OFF, inspect the crankshaft position sensor for looseness and correct installation.
锟斤拷If the crankshaft position sensor is loose, inspect the sensor and the O-ring for damage, replace as necessary.
2. Inspect the engine for the following conditions:
* Engine oil for debris and contamination
* Crankshaft reluctor wheel for damage
* The timing chain, tensioner, and sprockets for wear or damage
锟斤拷If debris is found in the engine oil, inspect the internal engine components to determine the cause. Repair or replace any worn or damaged
