Circuit/System Verification
1. Ignition OFF, inspect the engine wiring harness carrying the camshaft position sensor circuits for the following conditions:
* Close routing of aftermarket electrical equipment
* Close to solenoids, motors, and relays
瀚慖f any of these are determined to be a possible source of electrical interference, correct any wire harness routing or component placement
conditions.
2. Engine idling, observe the scan tool Camshaft Position Active Counter parameter. Parameter should be incrementing.
3. Engine idling, observe the DTC information with a scan tool. DTC P0341 or P0366 should not set.
4. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
1. Ignition OFF, inspect the camshaft position sensor for looseness and correct installation.
瀚慖f the camshaft position sensor is loose, inspect the sensor and the O-ring for damage, and replace as necessary.
2. Inspect the engine for the following conditions:
* Engine oil for debris
* Camshaft reluctor wheel for damage
* The timing chain, timing chain tensioner, and sprockets for wear or damage
瀚慖f debris is found in the engine oil, inspect the internal engine components to determine the cause. Repair or replace any worn or damaged
components.
Component Testing
Important: You must perform the Circuit/System Testing before proceeding with Component Testing.
1. Inspect the camshaft position sensor for correct installation. Remove the camshaft position sensor from the engine and inspect the sensor
O-ring for damage.
瀚慖f the sensor is loose, incorrectly installed, or damaged, replace the camshaft position sensor.
2. Connect the camshaft position sensor harness connector to the camshaft position sensor.
3. Ignition ON, engine OFF, observe the Camshaft Position Active Counter parameter on the scan tool.
4. Pass a flat steel object across the tip of the sensor repeatedly. The Camshaft Position Active Counter parameter should increment with each
pass of the steel object.
瀚慖f the parameter does not increment, replace the camshaft position sensor.
