• Check wires for short to one another.

If no wiring malfunction is detected and voltage was present between contacts 1+3:

• Replace Camshaft Position (CMP) sensor 2 -G40-.
• Check DTC Memory, if necessary, repair any malfunctions and then Erase DTC Memory, see DTC MEMORY, CHECKING AND ERASING (FUNCTIONS 02 AND 05) .
• Read readiness code, see READINESS CODE, READING . If DTC memory has been erased or engine control module was disconnected from permanent positive, readiness code must be generated again:

  Engine code AWW, see READINESS CODE FOR ENGINE CODE AWW, GENERATING

  Engine code AWP, see READINESS CODE FOR ENGINE CODE AWP, GENERATING

If no wiring malfunction is detected and no voltage was present between contacts 1+3:

• Replace engine control module, see ENGINE CONTROL MODULE, REPLACING .
