  1. Several tools will be instrumental in successfully diagnosing this code
  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. Some applications also utilize the inlet door to regulate air flow through the intake tube by adjusting the degree to which the door opens according to throttle position
  4. If the fuel shutoff switch and all system circuitry checks out, suspect a defective PCM (or other related controller)

If there is a clicking noise when you attempt to start the engine and the engine does not crank, it typically means there is something wrong with the battery, such as a low or discharged battery or corroded or loose battery cables. If the engine cranks when you attempt to start the car, but fails to turn over, this may mean there is a problem with the fuel or ignition. Other common reasons an engine may fail to start include a failure of the starter motor relay, a clogged fuel filter, a defective fuel pump or an ignition switch failure.

As a result, oxygen sensors are likely to report fuel mixture problems.
