What is an oxygen sensor?
The oxygen sensor, also known as an O2 sensor, gauges oxygen levels in the exhaust gases upon exiting the engine and transmits this data to the powertrain control module (PCM). Alongside inputs from the mass airflow (MAF) and manifold pressure temperature (MAP) sensors, the PCM uses this information to calculate the optimal air-to-fuel ratio for your engine.
Positioned near the catalytic converter within the vehicle's exhaust system, the sensor contributes to engine timing efficiency, thereby reducing emissions discharged by the vehicle.
When should I replace the oxygen sensor on my car?
Replace your oxygen sensor promptly upon observing these warning signs:
- Check engine light illumination
- Decreased gas mileage
- Presence of a rotten egg odor or black smoke from the exhaust
- Rough idling
