Start the engine and run it to normal operating temperature.
Check whether the fault is permanent or intermittent. Read off the signal from the intake camshaft reset valve.

Check that the signal is within its permitted range. The normal value with an idling engine at operating temperature is 400 - 900 mA.

The fault is permanent if the signal is incorrect. The fault is intermittent if the signal is correct.
