- Check cable between the camshaft position sensor terminal 2 and engine control module # A21 for an intermittent open-circuit, intermittent short-circuit to ground and an intermittent short-circuit to supply voltage.
- Check cable between camshaft position sensor terminal 3 and engine control module # A36 for an intermittent open-circuit.
