Code P0133 Infiniti Description
The P0133 Infiniti code indicates that there is a slow response from the O2 sensor in Bank 1 Sensor 1. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. Bank 1 refers to the side of the engine where cylinder 1 is located, and Sensor 1 indicates that it is the sensor located before the catalytic converter.
Common Causes of P0133 Infiniti
- Faulty O2 sensor
- Wiring issues or poor connections
- Exhaust leaks
- Vacuum leaks
- Engine misfires
Symptoms of P0133 Infiniti
