The oxygen sensor plays a critical role in your vehicle's engine management system. Positioned in the exhaust stream, it measures the oxygen concentration in exhaust gases and communicates that data back to the ECU, enabling the onboard computer to optimize the air/fuel mixture for peak efficiency. A failed or degraded O2 sensor can result in reduced fuel economy, rough engine idle, and incorrect ignition timing. The Spectra Premium OS6146 restores accurate sensor feedback so your engine management system can perform as intended.
