  • Engine Control Module (ECM)
  • Faulty Air fuel ratio (A/F) Sensor 1 Bank 1

At this point we are assuming that the fuses and relays are good. You will need to locate the PCM/TCM and the power input signal circuit using your vehicle information source.

Unplug the connector from the PCM/TCM, place the ignition switch in the ON position, and probe the appropriate circuit with the positive test lead of the DVOM.
