Code P0132 Cadillac Description
The P0132 Cadillac code indicates that there is a high voltage condition in the HO2S (Heated Oxygen Sensor) circuit for Bank 1 Sensor 1. The oxygen sensor is responsible for measuring the oxygen content in the exhaust gases and providing this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the voltage in the circuit is too high, it typically means that the oxygen sensor is stuck at a rich (high voltage) reading, which can lead to an incorrect air-fuel mixture being supplied to the engine.
Common Causes of P0132 Cadillac
- Faulty oxygen sensor
- Wiring harness issues
- Exhaust system leaks
- ECM malfunction
- Engine running too rich
Symptoms of P0132 Cadillac
