Common Symptoms For Ford Tickford C0766

  1. Many late model diesel fuel injectors are individually numbered for electronic identification
  2. If the resistance level does not decrease with heat and increase as it cools, replace the sensor. If everything has checked out thus far, turn the key to the "ON" position and test for the presence of a voltage (and a ground signal) at the exhaust gas temperature/pressure (or heated oxygen) sensor electrical connector
  3. 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 both circuits
  4. If the fuel shutoff switch and all system circuitry checks out, suspect a defective PCM (or other related controller)
