P0132 trouble code definition

02 Sensor Circuit High Voltage (Bank 1 Sensor 1)

What the P0132 code means

When the P0132 trouble code has been stored by the power control module, it is an indication of a problem with the 02 oxygen sensor. Specifically, that the oxygen sensor has stayed at a high voltage for too long without switching back.

What causes the P0132 code?

  • A short in the heater circuit of the oxygen sensor (bank 1 sensor 1)
  • Broken or exposed oxygen sensor wires
  • Excessively high fuel temperature

What are the symptoms of the P0132 code?

There are some cases where the driver does not experience any symptoms associated with this code. However, in addition to the Check Engine Light being on, the driver may experience an increase of fuel consumption, irregular shifting, and/or the engine cutting off.

If the P0132 trouble code is left on and unaddressed for an extended period of time, it can damage the catalytic converter.

How does a mechanic diagnose the P0132 code?

  • Takes a record of freeze frame data and all trouble codes that have been stored by the power control module (PCM), using an OBD-II scanner

  • Clears the P0132 trouble code which will turn off the Check Engine Light

  • Test drives the vehicle to see if the trouble code and check engine light comes back on

  • Uses the OBD-II scanner to view live data and monitor the voltage levels going to the oxygen sensor to ensure proper voltage

  • Checks the oxygen sensor wiring for broken or exposed wires

Common mistakes when diagnosing the P0132 code

  • In most cases, the oxygen sensor will need to be replaced to fix the problem and clear the P0132 trouble code from the power control module (PCM).

  • It is important not to overlook the oxygen sensor wiring and check for broken or exposed wires prior to replacing the oxygen sensor.

How serious is the P0132 code?

The P0132 trouble code is not widely considered a serious one.The driver may experience an increase in fuel consumption. Also keep in mind that a vehicle in this condition emits harmful pollutants into the air.

What repairs can fix the P0132 code?

Additional comments for consideration regarding the P0132 code

If the oxygen sensor has seized up in the exhaust pipe, a propane torch and oxygen sensor set will be necessary to remove it properly. It is also important to make sure the oxygen sensor wrench is attached to the sensor properly to prevent stripping during the removal process.

Mister Ron was very nice and took time out to explain any concerns I might have about my car. He also made sure he communicated with me when he was on his way, once he was outside, and when we was done working on my car. I appreciate that considering I have a newborn that I had to look after.
