This air-fuel ratio sensor (22641AA670) measures how much oxygen is in your exhaust. This component is also called a wideband or broadband sensor since it can detect a wide range of fuel mixtures for your car.

Once the sensor measures how much oxygen your exhaust has, it sends the data to your engine control unit (ECU). The ECU then adjusts the mixture to maintain the optimal air-to-fuel ratio for your car.

Over time, your A/F ratio sensor can get contaminated and have incorrect air-fuel mixture readings. The sensor can also malfunction due to extreme heat or faulty wiring. A defective car oxygen sensor can trigger your Check Engine light, reduce the fuel economy and engine power of your ride, or cause rough idling.

These oxygen sensors are designed to fit and work the same as the factory sensors on your ride.
