P0132 OBD-II Trouble Code

Technical Description

O2 Oxygen Sensor Circuit High Voltage (Bank1, Sensor1)

What does that mean?

This involves 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, that indicates the voltage at the sensor is over 1.5 volts. Other vehicles may be similar.

Symptoms

You will likely not notice any drivability problems.

Causes

A code P0132 may mean that one or more of the following has happened:

• The oxygen sensor heater circuit is shorted out
• The wiring to the sensor is broken / frayed (less likely)

Possible Solutions

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

If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:

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