This oxygen sensor uses a zirconia Nernst cell ceramic element to measure oxygen content in exhaust gases. As the air-fuel mixture shifts between rich and lean conditions, the sensor rapidly switches its voltage output, providing the ECU with real-time data for precise fuel adjustments. Each Bosch oxygen sensor undergoes rigorous testing including a 1,000-degree Celsius functional test and leak test to ensure reliable performance.

Replace your oxygen sensor if you experience poor fuel economy, rough idle, failed emissions tests, or diagnostic trouble codes such as P0131, P0132, P0133, or P0134. A worn oxygen sensor can negatively impact fuel efficiency, increase harmful emissions, and shorten catalytic converter life.
