  2. If either the reference voltage or ground circuits are open, use the digital volt/ohmmeter to check for continuity (disconnect all related control modules from the circuit before checking circuit resistance or controller damage may occur) and resistance in all circuits
  3. Intermittent conditions can prove to be quite a challenge to diagnose and in extreme cases may have to be allowed to worsen before a correct diagnosis can be made. If the fuel shutoff valve has not been deactivated by a collision, use the digital volt/ohmmeter to test voltage and ground signals at the valve itself
  4. If the code fails to immediately return, you may have an intermittent condition
