Walker Products 350-32013 oxygen sensor for the 1979-1981 Chevrolet Malibu V6 3.8L, the 1980-1981 Malibu V8 4.4L, 5.0L or 5.7L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns its fuel. It returns the diagnostic feedback the ECU expects for its application and position.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants

A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or light the malfunction indicator light. A damaged wiring harness or connector, or another fuel or ignition fault, can be behind those signs as well, so find the cause before you buy a sensor.

Frequently Asked Questions
Is this the right Chevy Malibu oxygen sensor for a 1979-1981 Chevrolet Malibu V6 3.8L?
Yes. Walker Products 350-32013 is listed for the 1979-1981 Chevrolet Malibu V6 3.8L and the 1980-1981 Malibu V8 4.4L, 5.0L or 5.7L. For other models, open the "Vehicles it fits" section.
Is this Walker Products oxygen sensor a narrow-band type?
Yes. Walker Products 350-32013 is a 2-wire, direct-fit narrow-band oxygen sensor.
Is this an upstream oxygen sensor?
Yes. The position is listed as upstream, covering upstream left, upstream right, upstream rear and upstream front.
What does the coating on this oxygen sensor protect?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes are a gas-permeable platinum layer.
How can I tell if the oxygen sensor wiring is damaged?
With the engine off and cool, look over the sensor, wiring harness and connector for physical damage. Newer vehicles also store fault codes in the ECU, and some relate to the sensor.
