P1460 Wide open throttle A/C cutoff relay circuit

P1460 Wide open throttle A/C cutoff relay circuit

Possible causes
  • Open or shorted WAC circuit.
  • Damaged WAC relay (or CCRM).
  • Open VPWR circuit to the WAC relay.
  • Damaged PCM.
    • Symptoms
    – Engine Light ON (or Service Engine Soon Warning Light)
    P1460 Description

    Monitors the wide open throttle A/C cutoff (WAC) circuit output from the PCM. The test fails if: When the PCM grounds the WAC circuit, excessive current draw is detected on the WAC circuit; or, with the WAC circuit not grounded by the PCM, voltage is not detected on the WAC circuit (the PCM expects to detect VPWR voltage coming through the WAC relay coil to the WAC circuit).
