Walker Products 250-54018 oxygen sensor for the 2002-2005 Jaguar X-Type V6 2.5L, the 2002-2008 X-Type V6 3.0L and other vehicles measures the oxygen in the exhaust gas to track the air-fuel ratio. This Walker Products oxygen sensor is a wide-band unit made for a specific application and position, so it gives the ECU the diagnostic feedback it needs.
- Wide-band air-fuel ratio sensor with 4 wires
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-54018 oxygen sensor
- Fits: the 2002-2005 Jaguar X-Type V6 2.5L, the 2002-2008 X-Type V6 3.0L and other vehicles
- Position: Upstream left, upstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and newer vehicles may store a fault code. Before replacing it, look over the sensor, its wiring harness and its connector for physical damage with the engine off and cool, since damage there can shorten a sensor's life. A shop can test the rest.
Fits
This oxygen sensor goes in the upstream left or upstream right position. It also fits the 2003-2006 Jaguar S-Type V6 3.0L or V8 4.2L and works as a Jaguar XK8 oxygen sensor on the 2003-2006 XK8 V8 4.2L. This listing is one sensor, and each upstream position takes one.

Frequently Asked Questions
Is this X-Type oxygen sensor right for the 2002-2005 Jaguar X-Type V6 2.5L?
Yes. Walker Products 250-54018 fits the 2002-2005 Jaguar X-Type V6 2.5L. For any other car, look it up by year and engine in the "Vehicles it fits" section.
Is this a Jaguar X-Type O2 sensor for the 2002-2008 X-Type V6 3.0L?
Yes. The 2002-2008 X-Type V6 3.0L is covered, and the sensor goes in either the upstream left or the upstream right position, one per position.
Is the Walker Products 250-54018 a wide-band sensor?
Yes. Walker Products 250-54018 is a 4-wire wide-band air-fuel ratio sensor with an M18 - 1.5 thread.
What does the coating on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. The coating keeps combustion residue and particulates in the exhaust gas from contaminating or eroding the electrode surfaces.
Does this oxygen sensor send diagnostic feedback to the ECU?
Yes. Each Walker Products part number is made for its specific application and fitment position, so it returns the diagnostic feedback the ECU requires.
