What It Helps Address

• Check engine light related to rear oxygen sensor performance
• Incorrect exhaust feedback from a worn heated O2 sensor
• Rough idle or drivability concerns tied to sensor signal issues
• Emission test failures caused by a failing rear sensor
• Replacement needs for rear left or rear right sensor locations on supported vehicles

Installation Notes and Tips

Confirm the exact sensor position on your vehicle before ordering, since this part is listed for rear, rear left, and rear right locations depending on application. Match the connector shape, wire count, and thread size to the original sensor before installation. For best results, verify fitment against the vehicle application tab and inspect the exhaust bung threads before threading in the new sensor.
