Checking the status




- Start the engine.
Check whether the fault is permanent or intermittent. Read off the fault status from the camshaft position (CMP) sensor. When the camshaft position (CMP) sensor is tested, "Diagnostic ready" must be displayed.
The fault is permanent if the fault status is "Fault found". The fault is intermittent if the fault status is "No fault detected".

Checking the component and wiring
Check the signal cable between engine control module (ECM) terminal #A60 (#A60) and camshaft position (CMP) sensor connector terminal #3. Check for a short-circuit to ground.
Check the power cable between engine control module (ECM) terminal #A16 (#A16) and camshaft position (CMP) sensor connector terminal #1. Check for an open-circuit.

Hint: With the ignition on and the camshaft position (CMP) sensor connector disconnected, the voltage between terminal #1 and ground terminal should be approximately 5 V.

Remedy as necessary.
