Walker Products Oxygen Sensor P/N:250-241242
Walker Products 250-24775 oxygen sensor for the 2002-2008 Mini Cooper 4-cylinder 1.6L measures the oxygen in the exhaust gas to gauge combustion efficiency. It is a direct-fit, narrow-band sensor that gives the ECU the diagnostic feedback it requires.
A rough-running engine, higher fuel consumption or a lit malfunction indicator light can mean the oxygen sensor is worn, though damage to the wiring harness or connector can be behind the same signs, so inspect both for physical damage with the engine off and cool.
This oxygen sensor is a direct-fit replacement for the 2002-2008 Mini Cooper 4-cylinder 1.6L (L4-1.6L).
Fit and size
Build and materials
One oxygen sensor. The 2002-2008 Mini Cooper 4-cylinder 1.6L takes one.
Product information is for general reference and may contain errors. See our Disclaimer.
Is this O2 sensor right for the 2002-2008 Mini Cooper 4-cylinder 1.6L?
Yes. Walker Products 250-24775 is a direct-fit oxygen sensor for the 2002-2008 Mini Cooper 4-cylinder 1.6L (L4-1.6L), and the fitment calls for one.
Is this Walker Products oxygen sensor an upstream or downstream sensor?
Walker Products 250-24775 is listed for both upstream and downstream positions. It is a narrow-band sensor.
What thread size does this narrow-band oxygen sensor have?
This oxygen sensor has an M18 - 1.5 thread.
Can a worn oxygen sensor make the engine run poorly?
Yes. A failed oxygen sensor can make the engine run poorly, raise fuel consumption or light the malfunction indicator light. A shop can read any fault code stored in the ECU.
What does the coating on this oxygen sensor protect against?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes carry a gas-permeable platinum layer.
