What is the P0132 Fault code? What does it all mean?
Many problems can be identified by increased fuel consumption, erratic engines and flashing check engine lights. If you receive the P0132 fault code from your OBD-II scanner it is likely that there is an issue with one of your oxygen sensors.
If the powertrain control module (PCM/ECM), receives too much voltage from the heated oxygen sensor, it will set fault code P0132. This is a sign that the oxygen sensor has not been responding fast enough to the engine’s mixture of air and fuel. This code can also be seen with rich fuel mixtures. (rich mixture = more air + fuel) Bank 1 indicates which side of the engine is cylinder 1. Sensor 1 is the O2 sensor upstream of the catalytic converter.
These sensors are located in your vehicle’s exhaust and have the primary task of controlling the amount unburned oxygen in it. The oxygen sensors monitor the oxygen levels in the exhaust system and transmit information to the PCM. This data helps the PCM determine how much fuel is required to achieve optimal performance.
The oxygen sensor may detect low oxygen levels in the exhaust. This could mean that the engine uses too much fuel and is running at a high level of fuel consumption. The PCM will adjust the amount fuel that is injected into the engine. In this case, the engine’s fuel consumption and emissions will increase while performance will suffer. For these processes to work smoothly, O2 sensors need to be in top condition at all times.
What Are the Possible Causes of the P0132 Fault Code
Depending on the make or model of your vehicle, there are several reasons that the P0132 fault code might be triggered. These are the most common reasons:
- – Rich mixture reasons
- – Short circuit in heater circuit of oxygen sensor (Bank 1, Sensor 1)
- – Broken cables or loose connections
- – Extremely high fuel temperatures
- – Defective O2 sensor
- – Defective PCM
What are the symptoms of the P0132 Fault code?
- – Illumination and control of the check engine light
- – Black smoke and bad odors from the exhaust
- RPM fluctuations at idle
- – Increased fuel consumption
- – Lower engine performance
- – Irregular gear changes (automatic)
- – Engine stalling
- If the fault persists, malfunctions of the catalytic convert may occur.
How do I fix the P0132 fault code?
- Replace or repair damaged or exposed cables
- Replace oxygen sensor (bank 1 sensor 1)
How serious is the P0132 fault code?
P0132 fault codes should not be considered serious. A driver might experience an increase in fuel consumption. Remember that vehicles in this condition can emit harmful gases into the atmosphere. The catalytic converter can fail if it is not addressed promptly. This will also cause problems with engine performance.
