P0132 - OBD Trouble Code


OBD Code P0132 - O2 Sensor Circuit High Bank 1 Sensor 1

<<See All OBD Codes

If you find out that the P0132 fault code has been stored by the powertrain control module, then it would indicate that there is some problem with the oxygen sensor. The issue would arise because the oxygen sensor might have stayed for a very high voltage for a long period of time without switching back.

The P0132 fault code can be defined as the oxygen sensor circuit high voltage bank 1 sensor 1. This is a trouble code which would highlight the issue in the O2 sensor circuit. This code would start indicating that the sensor has lagged or take longer period of time to switch from high to low voltage for too long.


It is very important to correct this error code due to the fact that a malfunctioning cylinder would lead to a spike in the fuel consumption. A car whose cylinder is in bad working conditions would emit a number of harmful gases like hydrocarbons and nitrogen oxides that would pollute the environment.


What causes this problem with the o2 Sensor Circuit High (Bank 1 Sensor 1)?


  • There can be a short in the heater circuit of the oxygen sensor bank 1 sensor 1
  • The oxygen sensor wires might be broken or exposed
  • There might be excessive high fuel temperature

Easy Diagnosis Of Engine Error OBD Code P0132

A record of freeze frame data should be taken and at the same time all trouble codes that have been stored by the power control module, this can be done by using an OBD-II scanner

The next step is to clear the P0132 trouble code due to which the check engine light would be turned off

The vehicle should be taken out for a test drive to see if the trouble code and check engine light comes back on

An OBD-II scanner should be used to view live data and monitor the voltage levels going to the oxygen sensor to ensure proper voltage

Carefully check the oxygen sensor wiring for broken or exposed wires


Common Mistakes When Diagnosing The P0132 Code


  • There can be some defects in the oxygen sensor/air fuel ratio sensor
  • The oxygen sensor/air fuel ratio sensor heater circuit might be defective
  • There can be some faults in the mass air flow sensor
  • High fuel pressure
  • Imperfect engine coolant temperature sensor
  • There can be some issues with the sensor wiring or the circuit
  • The powertrain control module software needs to be updated
  • Flaws in the powertrain control module
