Walker Products 250-24339 oxygen sensor for the 2004-2008 Chevrolet Malibu 4-cylinder 2.2L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a 4-wire narrow-band unit.
- Electrodes with a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel mixture
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Made for its specific application and mounting position, with the diagnostic feedback the ECU expects
Quick facts
- Part: Walker Products 250-24339 oxygen sensor
- Fits: the 2004-2008 Chevrolet Malibu 4-cylinder 2.2L and other vehicles
- Position: downstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light, but other faults can do the same. Before replacing it, look over the sensor, wiring harness and connector for physical damage with the engine off and cool.
Fits
The 2004-2008 Chevrolet Malibu 4-cylinder 2.2L, the 2002-2005 Chevrolet Trailblazer 6-cylinder 4.2L and the 2006 Trailblazer V8 5.3L or 6.0L, and the 2004-2005 Chevrolet Colorado 4-cylinder 2.8L or 5-cylinder 3.5L all fit this sensor, along with many other vehicles. This listing is one sensor, and the 2004-2008 Chevrolet Malibu 4-cylinder 2.2L takes one.

Frequently Asked Questions
Is this Malibu oxygen sensor right for a 2004-2008 Chevrolet Malibu 4-cylinder 2.2L?
Yes, Walker Products 250-24339 fits the 2004-2008 Chevrolet Malibu 4-cylinder 2.2L, and that car takes one. If your car is not one named on this page, look it up in the "Vehicles it fits" section.
Will this sensor work on a 2004-2005 Chevrolet Colorado 4-cylinder 2.8L or 5-cylinder 3.5L?
Yes. This sensor fits the 2004-2005 Chevrolet Colorado with either the 4-cylinder 2.8L or the 5-cylinder 3.5L, and each of those trucks takes one.
Is the 250-24339 a narrow-band or wideband oxygen sensor?
Walker Products 250-24339 is a narrow-band sensor with 4 wires and an M18 - 1.5 thread.
What does the coating on this oxygen sensor protect against?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
Can a failing oxygen sensor set a fault code on a newer vehicle?
Yes, newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems; a shop can read them to help find the cause.
