Walker Products 250-25042 oxygen sensor for the 2007-2009 Jeep Grand Cherokee V6 3.0L and other vehicles measures the oxygen in exhaust gas to gauge combustion efficiency. Each part number is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it expects.
- Monitors exhaust gases and helps reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Wide-band sensor that determines the oxygen content of the exhaust gas and monitors the air-fuel ratio
Quick facts
- Part: Walker Products 250-25042 oxygen sensor
- Fits: 2007-2009 Jeep Grand Cherokee V6 3.0L and other vehicles
- Position: Upstream, downstream, upstream left, upstream right
- Condition: New
A worn sensor can be behind poor running, higher fuel consumption or a lit malfunction indicator light, though a damaged wiring harness or connector can also lie behind those signs. Inspect both for physical damage before you replace the sensor.
Fits
The 2007-2009 Jeep Grand Cherokee V6 3.0L, the 2007-2008 Mini Cooper 4-cylinder 1.6L and the 2021-2024 Mercedes-Benz GLE63 AMG S V8 4.0L all fit this oxygen sensor, and so do many other vehicles. This listing is one sensor, and a 2007-2009 Jeep Grand Cherokee V6 3.0L takes one. If your car is not named here, look up its year, make and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is Walker Products 250-25042 the right oxygen sensor for a 2007-2009 Jeep Grand Cherokee V6 3.0L?
Yes. Walker Products 250-25042 is listed for the 2007-2009 Jeep Grand Cherokee V6 3.0L, and that vehicle takes one sensor.
Is this the oxygen sensor for a 2007-2008 Mini Cooper 4-cylinder 1.6L?
Yes, Walker Products 250-25042 is listed for the 2007-2008 Mini Cooper 4-cylinder 1.6L at one sensor per vehicle. For another car, enter its details in the "Vehicles it fits" section.
What type of sensor is this Walker Products oxygen sensor?
Walker Products 250-25042 is a wide-band oxygen sensor with an M18 - 1.5 thread. Its electrodes are made of a gas-permeable platinum layer.
Is the 250-25042 an upstream or a downstream oxygen sensor?
Walker Products 250-25042 is listed for upstream, downstream, upstream left and upstream right positions, depending on the application. Each part number is made for its specific application and fitment position.
Can a failing oxygen sensor like the 250-25042 turn on the malfunction indicator light?
Yes, a failed sensor can light the malfunction indicator light, and it can also bring poor running or higher fuel consumption. Newer vehicles store fault codes in the ECU, some tied to the sensor.
