P0132 P0132 OBD-II: O2 Sensor Circuit High Voltage
What P0132 means for you
This code indicates a potential issue with the oxygen sensor circuit, which can affect engine performance and emissions.
Symptoms
- The Check Engine Light will turn on
- The vehicle may experience rough idling or operation
- Fuel efficiency may decrease
- The engine may stall
- Black smoke may be emitted from the exhaust along with a foul odor
- In rare instances, the driver may not notice any significant issues
Common causes
- The oxygen sensor is designed to monitor the oxygen levels in the exhaust gases after combustion. This data is essential for the Powertrain Control Module (PCM) to optimize fuel efficiency. If the PCM identifies a malfunction or incorrect readings from the sensor, it will trigger code P0132.

The P0132 code signifies that the oxygen sensor circuit is reporting a high voltage condition. This can lead to improper fuel-air mixture adjustments, resulting in poor engine performance and increased emissions.
How a workshop diagnoses it
1. Use a high impedance Digital Volt Ohm Meter (DVOM) to check the voltage at the oxygen sensor connector. 2. Inspect the sensor and its wiring for any visible damage or corrosion. 3. Verify that the sensor is receiving the correct voltage and ground signals. 4. Conduct a test drive while monitoring the sensor data with a quality scan tool to replicate the conditions under which the code was set. 5. If necessary, replace the oxygen sensor and reset the monitors to confirm the repair.
Frequently asked questions
It is not advisable to continue driving with a P0132 code, as it may affect engine performance and emissions.
The cost to repair a P0132 code can vary, but it typically involves replacing the oxygen sensor, which can range from $100 to $300 depending on the vehicle.
Ignoring the P0132 code can lead to decreased fuel efficiency, increased emissions, and potential damage to the engine over time.
