DTC P0132: High Voltage Primary HO2S (Sensor 1) Circuit

1. Reset the PCM.
2. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on.
3. Check the primary HO2S (Sensor 1) output voltage with a scan tool or the HDS.

Is there 0.9 V or more?

YES - Go to step 4

NO - Intermittent failure The system is OK at this time. Check for poor connections or loose terminals at the primary HO2S (Sensor 1) and at the PCM.

4. Turn the ignition switch OFF.
5. Disconnect the primary HO2S (Sensor 1) 4P connector.




6. Connect primary HO2S (Sensor 1) 4P connector terminals No.1 and No.2 with a jumper wire.
7. Turn the ignition switch ON (II).
8. Check the primary HO2S (Sensor 1) output voltage with a scan tool or the HDS.

Is there 0.9 V or more?

YES - Go to step 9.

NO - Replace the primary HO2S (Sensor 1).

9. Turn the ignition switch OFF.




10. Connect PCM connector terminals A6 and A10 with a jumper wire.
11. Turn the ignition switch ON (II).
12. Check the primary HO2S (Sensor 1) output voltage with a scan tool or the HDS.

Is there 0.9 V or more?

YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM and then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.

NO - Repair open in the wire between the PCM (A6, A10) and the primary HO2S (Sensor 1).
