2000-2003 LS1 or LS6 Rear Oxygen Sensor ACDelco

If your Corvette's Oxygen Sensor is not functioning properly, you are robbing yourself of performance and money at the gas pump.

Rough running, poor fuel economy, "Service Engine Soon" light and excessive emissions are all indicators your Corvette's O2 Sensors may be faulty. Oxygen Sensors detect the oxygen content in exhaust gases. The PCM uses this information to continuously optimize the combustion process and control exhaust emissions.

This 2000-2003 Corvette Oxygen Sensor is part of ACDelco's Professional line of OE quality emission service parts. This is the rear O2 sensor that is located behind the catalytic converter. There are two rear oxygen sensors required per vehicle. Sold individually.
