Description

The Bosch oxygen sensor is a direct-fit upstream sensor designed for bank 2 (cylinders 4-6) before the catalytic converter. This sensor measures exhaust gases to help the vehicle's DME adjust fuel trim, which is crucial for engine performance and fuel consumption.

When oxygen sensors fail, symptoms can include reduced fuel mileage, failed emissions tests, a check engine light, and poor driveability. Bosch, a leading supplier of engine electronics and sensors, manufactures this OE-quality part in Germany.
