- Engine vacuum leaks.
Fixing Error Code p0132 Step By Step
Replace faulty oxygen sensor in bank 1 sensor 1 to address P0132 fault code.
- To fix OBDII code P0132, first, review the ‘Possible Causes’ mentioned above and visually examine the corresponding wiring harness and connectors.
- Ensure to check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.
- Next, if the wiring and connectors appear to be in good condition, proceed to test the oxygen sensor (bank 1 sensor 1) using a scan tool to check its performance.
- If the sensor is faulty, replace it with a new one.
- Finally, clear the fault code using the scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost Of Fixing p0132 Fault Code
Diagnosing and repairing fault code P0132 typically involves testing and replacing the oxygen sensor.
The cost to diagnose and fix OBD code P0132 depends on the estimated 1. 0hour repair time.
Labor rates usually range from $75 to $150 per hour, so the general cost could be between $75 and $150. Actual cost may vary based on shop rates and the complexity of the repair.
Details of the p0132 OBD Code
P0132 indicates a fault in the upstream oxygen sensor’s voltage being too high for too long.
OBD code P0132 means that the O2 sensor circuit high voltage (Bank 1 Sensor 1) has detected a high voltage condition.
This code is triggered by the Engine Control Module (ECM) based on the signal received from the upstream oxygen sensor in Bank 1 of the exhaust system.
The ECM monitors the voltage output of the oxygen sensor to determine if the airfuel mixture is too rich or too lean.
In the case of P0132, the ECM has detected a high voltage signal from the oxygen sensor, indicating a rich airfuel mixture.
Mechanic’s Tech Notes
Troubleshooting for fault code P0132 involves diagnosing the oxygen sensor circuit high voltage condition.
To diagnose and fix OBDII code P0132, which indicates a low voltage condition in the upstream oxygen sensor (Bank 1 Sensor 1), start by checking the sensor’s wiring harness and connector for any damage or corrosion.
Use a voltmeter to test the sensor’s voltage output while the engine is running.
A healthy sensor should fluctuate between 0. 1 to 0. 9 volts.
If the voltage remains steady or is below specification, the sensor may be faulty and require replacement.
Additionally, ensure the sensor is receiving proper power and ground.
If the issue persists after these checks, consider replacing the oxygen sensor.
FAQ
OBD code P0132 means Front Heated Oxygen Sensor Circuit High Voltage (Bank 1 Sensor 1). Check sensor, wiring, fuel system, and exhaust for issues.
Symptoms of P0132: Engine Light ON, High Fuel Consumption, Excessive Smoke from Exhaust. Causes: Faulty Front HO2S, wiring issues, fuel system problems. Fix: Inspect and repair related components.
Diagnose P0132 by checking Front HO2S Bank 1 and its wiring. Look for damage or poor connections. Repair as needed to fix the issue.
Wrap Up
If your check engine light is on and you’re experiencing poor fuel economy with OBDII code P0132, it may be caused by a faulty oxygen sensor, wiring issues, or a vacuum leak affecting the sensor’s readings.
To address P0132, check the oxygen sensor’s wiring and connectors for any damage or corrosion.
Test the sensor’s output using a scan tool and replace the oxygen sensor if necessary to ensure proper airfuel ratio monitoring by the engine control module.
