  2. Repair or replace any open, shorted, damaged, or corroded items as required and retest the system to make sure that repairs were successful
  3. As the reluctor ring passes by the electro magnetic sensor, the 5-volt reference signal is completed with the protruding metal surfaces
  4. 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
