P0132 high signal in the oxygen sensor circuit (bank 2, sensor 1)

OBD2 - P0132 - Technical Description

P0132 - O2 Sensor Circuit High Voltage (Bank1, Sensor1)

When a P0132 DTC was stored by the power control module, it indicates a problem with the 02 oxygen sensor. Specifically, the oxygen sensor remained at high voltage for too long without switching back.

What does trouble code P0132 mean?

This Diagnostic Trouble Code (DTC) is a generic transmission code, which means it applies to OBD-II equipped vehicles. Although general, specific repair steps may differ depending on the brand / model.

This applies to the front oxygen sensor on Bank 1. This code indicates that the heated oxygen sensor reading is too high.

In the case of Ford vehicles, this means the sensor voltage is greater than 1.5 V. Other vehicles may be similar.

Symptoms

You probably won't notice any handling issues.

Causes of the P0132 code

The P0132 code may mean that one or more of the following events have occurred:

• Short circuit in the oxygen sensor heater circuit
• Broken / worn sensor wiring (less likely)
• Broken or exposed oxygen sensor wires
• Excessively high fuel temperature

Possible solutions

The simplest thing is to reset the code and see if it comes back.

If the code returns, the problem is most likely in the bank 1 front oxygen sensor. You will most likely need to replace it, but you should also consider the following possible solutions:

• Check for wiring problems (shorted, frayed wires)
• Check oxygen sensor voltage

How does a mechanic diagnose a P0132 code?

• Records freeze frame data and any trouble codes that have been stored by the power management module (PCM) using an OBD-II scanner.
• Clears a P0132 DTC that turns off the Check Engine light.
• Test drive the vehicle to see if the DTC and check engine light come on.
• Uses an OBD-II scanner to view real-time data and monitor the voltage levels going to the oxygen sensor to ensure the correct voltage.
• Checks oxygen sensor wiring for broken or exposed wires.

Common Mistakes When Diagnosing Code P0132

• In most cases, the oxygen sensor will need to be replaced to correct the problem and clear the P0132 DTC from the Power Control Module (PCM).
• It is important not to overlook the oxygen sensor wiring and check for broken or exposed wires before replacing the oxygen sensor.

How serious is the P0132 code?

DTC P0132 is not considered serious. The driver may experience increased fuel consumption. Also be aware that a vehicle in this state emits harmful pollutants into the air.

What repairs can fix code P0132?

• Repair or replace broken or exposed wires
• Replace oxygen sensor (row 1 sensor 1)

Additional comments to consider regarding code P0132

If the oxygen sensor is stuck in the exhaust pipe, it will require propane burner и set of oxygen sensors. It's also important to make sure the oxygen sensor key is properly attached to the sensor to prevent stripping during the removal process.
