Camshaft Position Signal Output Circuit High

Diagnostic Fault Information






Circuit/System Description

The replicated cam signal is an engine control module (ECM) output that is an electrical duplicate of the cam sensor input. This output goes to the radio for active noise control based on engine speed.

Conditions for Running the DTC

The ignition is ON, engine running.

Conditions for Setting the DTC

The ECM detects that the commanded state of the driver and the actual state of the control circuit do not match for greater than 5 s.

Action Taken When the DTC Sets

DTCs P2615 and P2616 are a Type C DTCs.

Conditions for Clearing the DTC

DTCs P2615 and P2616 are a Type C DTCs.

Circuit/System Verification

1. Engine Idling, observe the control circuit status parameters listed below with a scan tool:

* Camshaft Position Signal Output Circuit High Voltage Test Status

* Camshaft Position Signal Output Circuit Low Voltage Test Status

Each parameter should display OK or Not Run.

2. 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, disconnect the harness connector at the K108 active noise cancellation module.

2. Ignition ON, radio ON, test for 5-7 V between the signal circuit terminal 5 and ground.

• If less than specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K20 ECM.

• If greater than specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the K20 ECM.

3. If all circuits test normal, replace the K108 active noise cancellation module.

Repair Instructions

Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
