Description
Oxygen sensors measure exhaust oxygen. Their signals are used by the vehicle computer to adjust the air/fuel ratio and test vehicle emissions. Degraded oxygen sensors can reduce the engines performance and fuel efficiency, and increase harmful tailpipe emissions. They can also illuminate the Check Engine Light and cause a car to fail an emissions test. Replace your faulty unit today to ensure your emissions are up to standard and that you're getting the most out of your vehicle.
This replacement oxygen sensor fits the left or right front, located before the catalyst.
