Walker Products 250-24729 oxygen sensor for the 2006-2009 Cadillac XLR V8 4.4L and the 2007-2009 XLR V8 4.6L measures the oxygen in the exhaust gas so combustion efficiency can be monitored. This Walker Products oxygen sensor is made for its specific application and position, and sends the diagnostic feedback the engine computer requires.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
- Electrodes made with a gas-permeable platinum layer
- Measures the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Helps fine-tune the air-fuel mixture to support fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24729 oxygen sensor
- Fits: 2006-2009 Cadillac XLR V8 4.4L and the 2007-2009 XLR V8 4.6L
- Position: Upstream left, upstream right
- Condition: New
An engine that runs poorly, higher fuel consumption or a lit malfunction indicator light can mean the sensor is worn, though the sensor's wiring harness and connector can be behind them too, so look them over for physical damage before you replace the sensor.
Fits
This sensor fits the 2006-2009 Cadillac XLR with the V8 4.4L and the 2007-2009 XLR with the V8 4.6L, in the upstream left or upstream right position.

Frequently Asked Questions
Is the Walker Products 250-24729 right for the 2006-2009 Cadillac XLR V8 4.4L?
Yes. Walker Products 250-24729 fits the 2006-2009 Cadillac XLR V8 4.4L and the 2007-2009 XLR V8 4.6L, in the upstream left or upstream right position.
Is this sensor an upstream or a downstream oxygen sensor?
It is an upstream sensor, listed for both the upstream left and upstream right positions. This listing is one sensor, and the fitment lists one per application.
What thread does the 250-24729 sensor have?
Walker Products 250-24729 has an M18 - 1.5 thread and is a narrow-band sensor.
What can a failing oxygen sensor cause?
It can cause the engine to run poorly, burn more fuel or light the malfunction indicator light. Newer vehicles store fault codes in the engine computer, and a shop can read them to see whether the sensor is involved.
What does the coating on this oxygen sensor do?
It shields the electrode surfaces from erosion and contamination by combustion residue and particulates in the exhaust. The electrodes carry a gas-permeable platinum layer.
