Walker Products Oxygen Sensor P/N:250-24947
Walker Products 250-24993 oxygen sensor for the 2013-2015 BMW X1 6-cylinder 3.0L and other vehicles reads the oxygen in the exhaust gas. That reading shows how efficiently the engine burns fuel, and the sensor passes diagnostic feedback to the ECU.
A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. A leaking exhaust, a damaged wiring harness or connector, or a fuel or ignition fault can be behind those signs too, so find the cause before buying.
This is a direct-fit oxygen sensor for the 2013-2015 BMW X1 6-cylinder 3.0L and the 2011-2013 BMW 335i xDrive 6-cylinder 3.0L. This listing is one sensor for the downstream position, and both cars need just one there.
Fit and size
Build and materials
Is this the right oxygen sensor replacement for the 2013-2015 BMW X1 6-cylinder 3.0L?
Yes. Walker Products 250-24993 is a direct-fit downstream sensor for the 2013-2015 BMW X1 6-cylinder 3.0L, and the car takes one.
Is this Walker Products oxygen sensor narrow-band?
Yes. Walker Products 250-24993 is a narrow-band, four-wire sensor made for the downstream position.
What is the coating on this oxygen sensor's electrodes for?
The electrodes carry a gas-permeable platinum layer. The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas.
How can I tell if a downstream oxygen sensor is going bad?
Rough running, higher fuel use or a lit malfunction indicator light can be signs of a failing sensor. With the engine off and cool, you can also look the sensor, harness and connector over for physical damage.
Does this sensor report back to the engine ECU?
Yes. Each Walker Products part number is made for its specific application and fitment position and gives the ECU the diagnostic feedback it needs. Newer vehicles can store related fault codes.
