WARNING: This page is about a different variant/trim than selected.

The numbers below refer to the step numbers on the diagnostic table.

2: This step verifies that the condition is present.
5: This step detects if there is electromagnetic interference (EMI) on the CMP sensor circuits.

Step	Action	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Engine Control Module Connector End Views or Engine Controls Connector End Views
1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2	Turn ON the ignition, with the engine OFF. Clear the DTCs with a scan tool. Start the engine. Observe the DTC information with a scan tool. Did DTC P0341 or P0346 fail this ignition?	Go to Step 3	Go to Step 4
3	Did any other DTCs fail this ignition cycle?	Go to Diagnostic Trouble Code (DTC) List - Vehicle in Vehicle DTC Information	Go to Step 5
4	Observe the Freeze Frame/Failure Records for this DTC. Turn OFF the ignition for 30 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	Go to Step 5	Go to Intermittent Conditions
5	Inspect the camshaft position (CMP) sensor circuits for the following conditions: For being routed too close to the ignition coils For being routed too close to aftermarket electrical equipment For being routed too close to solenoids, relays, and motors Did you find and correct the condition?	Go to Step 10	Go to Step 6
6	Test for an intermittent and for a poor connection at the affected CMP sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 10	Go to Step 7
7	Test for an intermittent and for a poor connection at the engine control module (ECM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 10	Go to Step 8
8	Remove the affected CMP sensor. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake orCamshaft Position Sensor Replacement - Bank 2 (Left Side) Intake . Inspect the CMP sensor and the camshaft actuator reluctor wheel for the following conditions: Incorrect sensor installation A cracked or damaged sensor The sensor coming in contact with the reluctor wheel Excessive air gap between the reluctor wheel and the sensor Foreign material passing between the sensor and the camshaft reluctor wheel Camshaft reluctor wheel damage If you find a condition with the CMP sensor or the camshaft reluctor wheel, refer to one of the following procedures: Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake Camshaft Position Sensor Replacement - Bank 2 (Left Side) Intake Camshaft Position Actuator Replacement - Bank 1 (Right Side) Intake Camshaft Position Actuator Replacement - Bank 2 (Left Side) Intake Did you find and correct the condition?	Go to Step 10	Go to Step 9
9	Replace the CMP sensor. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake or Camshaft Position Sensor Replacement - Bank 2 (Left Side) Intake . Did you complete the replacement?	Go to Step 10	-
10	Clear the DTCs with a scan tool. Turn OFF the ignition for 30 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	Go to Step 2	Go to Step 11
11	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	Go to Diagnostic Trouble Code (DTC) List - Vehicle in Vehicle DTC Information	System OK
