Test Description

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

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

  1. 2:  This step verifies that the fault is present.
  2. 4:  This step tests the CMP sensor signal circuit. Applying a ground causes the CMP signal Active Counter to increment when its touched if the circuit and the ECM are operating properly.
  3. 5:  This step measures the resistance of the CMP sensor signal circuit.
DTC P0342

Step Action Values Yes No

1 Did you perform the Diagnostic System Check-Engine Controls? - Go to Step 2  Go to Diagnostic System Check - Engine Controls
2 
  1. Start the engine.
  2. Monitor the camshaft position (CMP) Active Counter parameter with the scan tool.
Does the CMP Active Counter increment?		 - Go to Step 3  Go to Step 4 
3
  1. Observe the Freeze Frame/Failure Records for this DTC.
  2. Turn OFF the ignition for 30 seconds.
  3. Start the engine.
  4. 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.
Does the DTC fail this ignition?		 - Go to Step 4  Go to Diagnostic Aids

  1. Turn ON the ignition, with the engine OFF.
  2. Disconnect the CMP sensor.
  3. Momentarily and repeatedly probe the CMP sensor signal circuit at the CMP harness connector with a test lamp connected to a good ground.
Does the CMP Active Counter increment each time the test lamp contacts the circuit?		 - Go to Step 8  Go to Step 5 
5 
  1. Turn OFF the ignition.
  2. Disconnect the ECM.
  3. Measure the resistance of the CMP sensor signal circuit. Refer to Circuit Testing in Wiring Systems.
Does the resistance measure more than specified value?		 5ohm Go to Step 6  Go to Step 7 
6 Repair the CMP sensor signal circuit for an open or high resistance. Refer to Wiring Repairs in Wiring Systems.
Did you complete the repair?		 - Go to Step 14  -
7
IMPORTANT: Disconnecting the ECM may remove the short from the circuit.
Test the CMP sensor signal circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.Did you find and correct the condition?		 - Go to Step 14  Go to Step 9 
8 Test for an intermittent and for a poor connection at the 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 14  Go to Step 10 
9 Test for an intermittent and for a poor connection at the 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 14  Go to Step 13 
10 Remove the CMP sensor. Refer to Camshaft Position (CMP) Sensor Replacement .
Inspect the sensor for signs of physical damage.
Did you find and correct the condition?		 - Go to Step 14  Go to Step 11 
11
  1. Inspect the reluctor wheel for damage or looseness. Refer to Diagnostic Aids.
  2. If you find damage to the reluctor wheel, refer to Camshaft Replacement - Left in Engine Mechanical.
Did you find and correct the condition?		 - Go to Step 14  Go to Step 12 
12 Replace the CMP sensor. Refer to Camshaft Position (CMP) Sensor Replacement .
Did you complete the replacement?		 - Go to Step 14  -
13 Replace the ECM. Refer to Engine Control Module (ECM) Replacement .
Did you complete the replacement?		 - Go to Step 14  -

  1. Clear the DTCs with a scan tool.
  2. Turn OFF the ignition for 30 seconds.
  3. Start the engine.
  4. 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.
Does the DTC fail this ignition?		 - Go to Step 15  Go to Step 2 
15 Observe the Capture Info with a scan tool.
Are there any DTC's that have not been diagnosed?		 - Go to Diagnostic Trouble Code (DTC) List System OK
