Walker Products 250-54053 oxygen sensor for the 1999-2003 Jaguar Vanden Plas V8 4.0L and other vehicles measures the oxygen in the exhaust gas. This 4-wire, wide-band air fuel ratio sensor reports the oxygen content so combustion efficiency can be monitored.
A worn sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light, though a damaged wiring harness or connector may be behind those signs too. Inspect both for physical damage before you replace the sensor.
This oxygen sensor fits the 1999-2003 Jaguar Vanden Plas V8 4.0L, the 1999-2003 Jaguar XJ8 V8 4.0L and the 1999-2003 Jaguar XJR V8 4.0L, in the upstream left and upstream right positions. It is listed for a wide range of Jaguar models, so if your car is not named here, look it up on the Buyer's Guide tab. This listing is one sensor, and the fitment calls for a quantity of one.
Fit and size
Build and materials
Will this Jaguar XJ8 oxygen sensor fit a 1999-2003 model with the V8 4.0L engine?
Yes. Walker Products 250-54053 is listed for the 1999-2003 Jaguar XJ8 V8 4.0L, in the upstream left and upstream right positions, with a quantity of one.
What type of Walker Products oxygen sensor is the 250-54053?
The Walker Products 250-54053 is a 4-wire, wide-band air fuel ratio sensor with an M18 - 1.5 thread. Its electrodes carry a gas-permeable platinum layer.
What signs can point to a worn upstream oxygen sensor?
Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean the sensor is worn. Newer cars store fault codes in the ECU, which a shop can read.
Is the 250-54053 sensor for the upstream left or the upstream right side?
It is listed for both the upstream left and upstream right positions. This listing is one sensor.
What does the coating on the Walker Products 250-54053 electrodes do?
The coating on the electrode surfaces helps keep combustion residue and particulates in the exhaust gas from contaminating or eroding them.
