POWERTRAIN CONTROL MODULE

Diagnostic Test
1. FUSED ENGINE CONTROL RELAY OUTPUT CIRCUIT OPEN





Turn the ignition off.
Disconnect the CMP Sensor harness connector.

Note: Check connectors-Clean/repair as necessary. Turn the ignition on. Measure the voltage of the Fused Engine Control Relay Output circuit at the CMP Sensor harness connector.

Is the voltage above 10 volts?
Yes>> Go To 2
No>> Repair the Fused Engine Control Relay Output circuit for
an open.
Perform Powertrain Verification Test - Ver 2

2. SENSOR GROUND CIRCUIT OPEN





Turn the ignition off.
Disconnect the PCM harness connector.

Note: Check connectors-Clean/repair as necessary.

Measure the resistance of the Sensor Ground circuit from the CMP Sensor harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes>> Go To 3
No>> Repair the Sensor Ground circuit for an open.
Perform Powertrain Verification Test - Ver 2

3. CMP SIGNAL CIRCUIT SHORTED TO VOLTAGE





Turn the ignition on.
Measure the voltage of the CMP Signal circuit at the CMP Sensor harness connector.
Is the voltage above 1.0 volt?
Yes>> Repair the CMP Signal circuit for a short to voltage.
Perform Powertrain Verification Test - Ver 2
No>> Go To 4

4. CMP SIGNAL CIRCUIT SHORTED TO GROUND





Turn the ignition off.
Measure the resistance between ground and the CMP Signal circuit.
Is the resistance below 100 ohms?
Yes>> Repair the CMP Signal circuit for a short to ground.
Perform Powertrain Verification Test - Ver 2
No>> Go To 5

5. CMP SIGNAL CIRCUIT OPEN





With the ignition off.
Measure the resistance of the CMP Signal circuit from the CMP Sensor
harness connector to the PCM harness connector.
Is the resistance below 5.0 ohms?
Yes>> Go To 6
Perform Powertrain Verification Test - Ver 2
No>> Repair the CMP Signal circuit for an open.
Perform Powertrain Verification Test - Ver 2

6. CAMSHAFT POSITION SENSOR





With the ignition off.
Replace the Camshaft Position Sensor.
Attempt to start the engine.
With the DRB III, read engine DTCs.
Did the DTC, (P0341) CAMSHAFT POSITION SENSOR PERFORMANCE, set again?
Yes>> Replace and program the Powertrain Control Module.
Perform Powertrain Verification Test - Ver 2
No>> Test Complete.
