What is an Oxygen Sensor and Why is it Important?
The oxygen sensor, also known as the O2 sensor, is a critical component of your vehicle’s emissions system. It monitors the amount of oxygen in the exhaust gases and sends this information to the engine control unit (ECU). The ECU then adjusts the air-fuel mixture to ensure optimal combustion, improving fuel efficiency and reducing harmful emissions.
Signs of a Failing Oxygen Sensor
- Check Engine Light: This is the most common indicator.
- Poor Fuel Economy: A faulty sensor can cause your car to burn more fuel than necessary.
- Rough Idling: Your engine may shake or stall when idling.
- Failed Emissions Test: A bad O2 sensor can cause your car to fail an emissions test.
