Built to OE specifications, the Bosch 16153 features a robust stainless steel body and premium sensing elements designed to withstand extreme exhaust temperatures and harsh underhood conditions. Common symptoms of a failing O2 sensor include a check engine light, poor fuel economy, rough idle, and increased exhaust emissions. DTCs such as P0131, P0132, P0133, P0134, and P0135 may indicate the need for replacement. As the original inventor of the automotive oxygen sensor, Bosch brings unmatched expertise and quality to every unit.
