DTC P0132:00, P0152:00 [MZI-3.7]

id0102d2334800

DTC P0132:00 DTC P0152:00 | P0132:00: A/F sensor (RH) circuit high voltage P0152:00: A/F sensor (LH) circuit high voltage
--- | ---
DETECTION CONDITION | • P0132:00 indicates A/F sensor (RH) circuit high voltage. • P0152:00 indicates A/F sensor (LH) circuit high voltage. • The A/F sensor signals are monitored for an over voltage condition. The code is set when the A/F sensor signal voltage is above the threshold value.
POSSIBLE CAUSE | • A/F sensor connector or terminal malfunction • Short to power supply in A/F sensor • P0132:00: Short to power supply between A/F sensor (RH) terminal H and PCM terminal 2AC • P0152:00: Short to power supply between A/F sensor (LH) terminal H and PCM terminal 2AE • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VISUALLY INSPECT A/F SENSOR WIRING HARNESS Note • Disconnect the A/F sensor wiring harness connector. Only the suspect A/F sensor needs to be diagnosed. • Turn the ignition switch off. • Disconnect the suspect A/F sensor connector. • Visually inspect the A/F sensor wiring harness. ― Check the connector (both halves) for contamination ― Make sure the connector pins are fully seated • Is a concern present? | Yes | Repair if necessary. Go to Step 8.
No | Go to the next step.
4 | INSPECT A/F SENSOR SIGNAL LEVEL TOO HIGH • Connect suspect A/F sensor connector. • Start the engine run it at idle. • Access and monitor the following suspect A/F sensor signal PIDs. ― P0132:00: O2S11 ― P0152:00: O2S21 • Race the engine several times. • Does the PID value change? | Yes | Go to the next step.
No | Go to Step 6.
5 | PERFORM THOROUGH WIGGLE TEST ON A/F SENSOR WIRING HARNESS • Turn the ignition switch off. • Turn the ignition switch to the ON position (engine off). • Access and monitor the A/F sensor signal PID at Step 4. • Perform a thorough wiggle test on the suspect A/F sensor wiring harness. • Does the voltage change during the wiggle test? | Yes | Repair if necessary. Go to Step 8.
No | Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”. Then go to the next step.
6 | INSPECT A/F SENSOR SIGNAL FOR SHORT CIRCUIT TO POWER SUPPLY INSIDE SENSOR • Turn the ignition switch off. • Disconnect the suspect A/F sensor connector. • Start the engine and run it at idle. • Access and monitor the suspect A/F sensor signal PID at Step 4. • Race the engine several times. • Does the PID value change? | Yes | Replace the suspect A/F sensor. (See AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION [MZI-3.7].) G to Step 9.
No | Go to the next step.
7 | INSPECT A/F SENSOR CIRCUIT FOR SHORT CIRCUIT TO POWER SUPPLY IN WIRING HARNESS • Suspect A/F sensor connector is disconnected. • Turn the ignition switch off. • Disconnect the PCM connector. • Turn the ignition switch to the ON position (engine off). • Measure the voltage between suspect A/F sensor terminal H (wiring harness-side) and ground. • Is any voltage present? | Yes | Repair for a short circuit, then go to the next step.
No | Go to the next step. (The system is operating normal at this time. The concern may have been caused by a loose or corroded connector.)
8 | VERIFY TROUBLESHOOTING OF DTC P0132:00, P0152:00 HAS BEEN COMPLETED • Verify that all disconnected connectors are reconnected. • Clear the DTC from the PCM memory using the M-MDS. • Perform the KOER self-test. (See KOEO/KOER SELF TEST [MZI-3.7].) • Is the PENDING CODE for this DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
