Walker Products 250-24408 center oxygen sensor for the 2005-2010 Volvo S40 5-cylinder 2.4L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a 4-W direct-fit narrow-band unit made for its specific application and position, and it gives the ECU the diagnostic feedback it needs.
- Narrow-band sensor that tracks combustion efficiency through the oxygen in the exhaust gas
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Reads oxygen levels to help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24408 oxygen sensor
- Fits: 2005-2010 Volvo S40 5-cylinder 2.4L and other vehicles
- Position: Center, downstream
- Condition: New
A failing sensor can show up as an engine that runs poorly, higher fuel consumption, more exhaust emissions or a lit check engine light. Before you replace it, rule out physical damage to the wiring harness and connector, because those signs can come from other faults too.
Fits
The fitment covers a wide range of Volvo models, including the 2005-2010 Volvo V50 5-cylinder 2.4L and the 1999-2001 Volvo V70 5-cylinder 2.4L. This listing is one sensor, and the center, downstream position on these cars calls for a single one.

Frequently Asked Questions
Is this V70 oxygen sensor right for the 1999-2001 Volvo V70 5-cylinder 2.4L?
Yes. Walker Products 250-24408 is listed for the 1999-2001 Volvo V70 with the 5-cylinder 2.4L, in the center, downstream position. If yours is another Volvo, look it up in the "Vehicles it fits" section.
Does this Volvo S40 oxygen sensor fit the 2005-2010 5-cylinder 2.4L?
Yes. Walker Products 250-24408 is listed for the 2005-2010 Volvo S40 5-cylinder 2.4L, and the car takes one sensor in the center, downstream position.
What thread size does the Walker 250-24408 oxygen sensor have?
It has an M18 - 1.5 thread and is a 4-W narrow-band sensor.
How can I tell if a downstream oxygen sensor is failing?
A failing sensor can show up as the engine running poorly, higher fuel use or a lit check engine light. A shop can read the fault codes stored in the ECU to see whether any relate to the sensor.
What does the coating on this narrow-band oxygen sensor protect?
The electrodes use a gas-permeable platinum layer, and a coating protects their surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
