Bosch 16138 oxygen sensor for the 2014-2020 Mini Cooper 4-cylinder 2.0L, the 2014-2021 Cooper 3-cylinder 1.5L and other vehicles measures the oxygen in the exhaust and sends air-fuel-ratio readings to the ECU. This downstream sensor is a heated narrow-band type that helps the engine hold stable combustion and reduce emissions.
- Heated narrow-band switching-type design with an integrated heater element
- Reaches operating temperature in under 10 seconds for quick closed-loop control
- Withstands exhaust streams up to 1,880°F
- Metal housing and a TSP coating that resist vibration, corrosion and contamination
- Advanced ceramic element and optimized heater control keep the signal steady under heat and vibration

A failing downstream sensor can show up as a check engine light, a drop in fuel economy or a rough idle, and those signs can come from other faults too. With the engine off and cool, look over the sensor wiring and connector for damage, and have the real cause of the code found before you replace the sensor; a shop can run the live tests.
