P0132 O2 Sensor Circuit High Voltage (Bank 1 Sensor 1)
You will likely not notice any drivability problems.
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)
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
