Walker Products 350-31024 oxygen sensor for the 1999 Chevrolet Malibu 4-cylinder 2.4L and other vehicles reads the oxygen content of the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a narrow-band, upstream unit that sends the ECU the diagnostic feedback it needs.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Coated electrodes with a gas-permeable platinum layer
- Measures oxygen levels to help fine-tune the air-fuel mixture
- Monitors exhaust gases to help reduce pollutants
- Made for its specific application and fitment position
Quick facts
- Part: Walker Products 350-31024 oxygen sensor
- Fits: 1999 Chevrolet Malibu 4-cylinder 2.4L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or turn on the check engine light. Those signs have other possible sources, so look the sensor, wiring harness and connector over for visible damage, with the engine off and cool, before replacing it.
Fits
The vehicles it fits include the 1999 Chevrolet Malibu 4-cylinder 2.4L, the 1995-2002 Saturn SC1 4-cylinder 1.9L and the 1995-2002 Saturn SC2 4-cylinder 1.9L, as a direct-fit replacement. Owners of any other car can look up their year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right Chevy Malibu oxygen sensor for the 1999 Malibu with the 4-cylinder 2.4L?
Yes. Walker Products 350-31024 is an upstream oxygen sensor listed for the 1999 Chevrolet Malibu 4-cylinder 2.4L, and that car takes one.
Is this a Saturn SC2 oxygen sensor for the 1995-2002 model with the 4-cylinder 1.9L?
Yes. Walker Products 350-31024 is listed for the 1995-2002 Saturn SC2 4-cylinder 1.9L, which takes one sensor. For another year or engine, look up your car in the "Vehicles it fits" section.
Which position is the Walker Products 350-31024, upstream or downstream?
Upstream. This Walker Products 350-31024 is a narrow-band oxygen sensor with an M18 - 1.5 thread.
How would I know this upstream oxygen sensor is failing?
A failed sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or light the check engine lamp. Newer cars may also store fault codes in the ECU.
Why are the electrodes on this oxygen sensor coated?
The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces. The electrodes carry a gas-permeable platinum layer.
