Bosch 17118 oxygen sensor for the 2017-2020 Land Rover Discovery V6 3.0L and other vehicles reports the exhaust air-fuel ratio to the ECU. This upstream wideband A/F oxygen (O2) sensor gives the ECU more detailed readings than a traditional switching sensor.
- Wide-band design measures the air-fuel ratio continuously across the full lambda range
- Reaches operating temperature in under 7 seconds for quick closed-loop control
- Metal housing with an integrated heater element and a TSP coating that resists vibration, corrosion and contamination
- Withstands exhaust gas temperatures up to 1,880°F
Quick facts
- Part: Bosch 17118 oxygen sensor
- Fits: the 2017-2020 Land Rover Discovery V6 3.0L and other vehicles
- Position: Upstream
- Material: Metal housing
- Condition: New
A worn upstream sensor can show up as a check engine light, a rough idle or poorer fuel economy. Those signs alone do not prove the sensor is at fault, since an intake vacuum leak can also set them off, so find the cause before you replace it.
Fits
The vehicles it fits include the 2013-2018 Land Rover Range Rover V8 5.0L, the 2014-2019 Range Rover V6 3.0L, the 2014-2018 Land Rover Range Rover Sport V8 5.0L and the 2014-2019 Range Rover Sport V6 3.0L. This listing is one sensor, and the 2017-2020 Land Rover Discovery V6 3.0L takes two.
