Bosch 17083 oxygen sensor for the 2014-2020 Mini Cooper 4-cylinder 2.0L, the 2014-2021 Cooper 3-cylinder 1.5L and other vehicles reports the air-fuel ratio to the ECU for fuel control. As a wideband sensor, it gives the ECU more detailed readings than a switching sensor.
- Continuous, high-precision air-fuel ratio measurement across the full lambda range
- Reaches operating temperature in under 7 seconds for quick closed-loop control
- Metal housing, integrated heater element and TSP coating that resist vibration, corrosion and contamination
- Withstands exhaust streams up to 1,880°F

A check engine light, rough running or lower fuel economy can be a sign the sensor is failing, but other faults can produce them too, so find the cause first. With the engine off and cool, look over the harness and connector for chafing or melted insulation. A shop can read the codes and test the sensor.
