DTC P0132, P0152 [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed))

BME010200100W18

DTC P0132 DTC P0152 | HO2S (RF) circuit high input HO2S (LF) circuit high input
--- | ---
DETECTION CONDITION | • The PCM monitors the input voltage from the HO2S (RF/LF). If the input voltage from the HO2S (RF/LF) sensor is above 1.2 V for 0.8 s, the PCM determines that circuit input is high. Diagnostic support note • This is a continuous monitor (HO2S). • The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.
POSSIBLE CAUSE | • HO2S (RF/LF) malfunction • Short to power in wiring harness between HO2S (RF) terminal A and PCM terminal 18 • Short to power in wiring harness between HO2S (LF) terminal A and PCM terminal 19 • HO2S (RF/LF) or PCM terminal shorted • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAVE BEEN RECORDED • Have FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS (HO2S related) been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA and DIAGNOSTIC MONITORING TEST RESULTS on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Check related Service Information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to the available Service Information. • If vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VERIFY RELATED PENDING OR STORED DTC • Turn the ignition switch off, then to the ON position (Engine off). • Verify pending code or stored DTCs using the WDS or equivalent. • Is other DTC present? | Yes | Go to the appropriate DTC troubleshooting procedures. (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
No | Go to the next step.
4 | IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Is DTC P0132 and P0152 on FREEZE FRAME DATA? | Yes | Go to the next step.
No | Go to troubleshooting procedures for DTC on FREEZE FRAME DATA. (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
5 | INSPECT FRONT HO2S SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch off. • Disconnect the suspected HO2S connector for P0132 (RF) or P0152 (LF). • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between suspected front HO2S terminal A (wiring harness-side) and body ground.
• Is any voltage reading?
Yes
Repair or replace the wiring harness short to power supply, then go to Step 7.
No | Go to the next step.
6 | VERIFY CURRENT INPUT SIGNAL STATUS • Start the engine. • Access O2S11 PID for P0132 or O2S12 PID for P0152 using the WDS or equivalent. • Verify PID while racing the engine at least 10 times in PARK. • Does PID remain above 0.45 V? | Yes | Replace the sensor, then go to the next step.
No | Go to the next step.
7 | VERIFY TROUBLESHOOTING OF DTC P0132 or P0152 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position. (Engine off) • Clear the DTC from the memory using the WDS or equivalent. • Run PCM adaptive memory procedure drive mode and HO2S heater, HO2S, and TWC Repair Verification Drive Mode.
(See OBD DRIVE MODE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
• Is the PENDING CODE of same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [AJ].)
No | Go to the next step.
8 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [AJ].) • Are any DTC present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
No | Troubleshooting completed.
