[QUOTE="hotcobra03, post: 9909919, member: 53096"] o2 codes..135/155 P0135 - HO2S Sensor Circuit Malfunction (HO2S-11) During testing the HO2S Heaters are checked for opens/shorts and excessive current draw. The test fails when current draw exceeds a calibrated limit and/or an open or short is detected. Short to VPWR in harness or HO2S. Water in harness connector. Open VPWR circuit. Open GND circuit. Low battery voltage. Corrosion or poor mating terminals and wiring Damaged HO2S heater. Damaged PCM. Wiring. Damaged HO2S heater. Damaged PCM. P0155 - HO2S Sensor Circuit Malfunction (HO2S-21) See DTC P0135 1460 P1460 - Wide Open Throttle A/C Cutout Primary Circuit Malfunction NOTE: For applications that use a normally open relay to control the A/C clutch, the following description applies to the A/C clutch relay control circuit. 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). Open or shorted WAC circuit Damaged WAC relay (or CCRM) Open VPWR circuit to WAC relay Damaged PCM When the WACF PID reads YES, a fault is currently present An open circuit or short to ground can only be detected when the PCM is not grounding the circuit A short to power can only be detected when the PCM is grounding the circuit During KOEO and KOER self-test, the WAC circuit will be cycled ON and OFF Verify A/C and defrost were OFF during KOEO and KOER self-test (Check ACCS PID to verify) If vehicle is not equipped with A/C, DTC P1460 can be ignored [/QUOTE]
