Walker Products 250-24611 oxygen sensor for the 2014-2016 BMW X6 V8 4.4L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor passes its readings to the ECU as diagnostic feedback.
- Measures exhaust oxygen to help fine-tune the air-fuel mixture and fuel economy
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Four-wire narrow-band design made for its specific application and fitment position
Quick facts
- Part: Walker Products 250-24611 oxygen sensor
- Fits: 2014-2016 BMW X6 V8 4.4L and other vehicles
- Position: Upstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A bad sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a damaged wiring harness is another common culprit. If the sensor is the cause, this one replaces it.
Fits
The 2014-2016 BMW X6 V8 4.4L, the 2000-2003 BMW X5 V8 4.4L, the 2001-2006 X5 6-cylinder 3.0L, the 2002-2003 X5 V8 4.6L and the 2003-2006 BMW Z4 6-cylinder 2.5L or 3.0L each take one of these sensors, and so do many other vehicles. This listing is a single sensor. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this a BMW X5 oxygen sensor for the 2000-2003 BMW X5 V8 4.4L?
Yes. Walker Products 250-24611 fits the 2000-2003 BMW X5 V8 4.4L, the 2001-2006 X5 6-cylinder 3.0L and the 2002-2003 X5 V8 4.6L, and each takes one.
Does this BMW X6 oxygen sensor fit the 2014-2016 BMW X6 V8 4.4L?
Yes. Walker Products 250-24611 fits the 2014-2016 BMW X6 V8 4.4L. The vehicle takes one, and this listing is a single sensor.
What thread does this 4-wire oxygen sensor have?
This narrow-band oxygen sensor has an M18 - 1.5 thread and four wires.
How do I check whether this oxygen sensor has failed?
Newer vehicles store fault codes in the ECU, and some point to the affected sensor. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage.
What does the platinum layer on this oxygen sensor do?
The electrodes have a gas-permeable platinum layer. Its coating keeps combustion residue and exhaust particulates from contaminating or eroding the electrode surfaces.
