Description

Walker 250-25144 oxygen sensor for the 2017-2019 BMW M760i xDrive V12 6.6L reads the oxygen content of the exhaust gas. This Walker oxygen sensor is made for its specific application and position, and it gives the ECU the diagnostic feedback it needs.

Monitors the air-fuel ratio to check combustion efficiency and help fuel economy
Monitors exhaust gases to help reduce pollutants
Electrodes made with a gas-permeable platinum layer
Electrode coating protects the surfaces from contamination and erosion by combustion residue and particulates

Quick facts

What does a Walker products oxygen sensor measure?

It measures the oxygen content of the exhaust gas and monitors the air-fuel ratio, which shows how efficiently combustion is running.

Does this Walker O2 sensor have a protective coating on its electrodes?

Yes. The electrodes are made with a gas-permeable platinum layer. The coating helps prevent contamination and erosion of the electrode surfaces by combustion residue and particulates.

Can the ECU store a fault code when this oxygen sensor fails?

Yes. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its systems. A shop can read them with a scan tool.

Is the Walker 250-25144 sold as a single oxygen sensor?

Yes. The Walker 250-25144 listing is one oxygen sensor, and the quantity per vehicle is one.
