Walker Products 350-34134 oxygen sensor for the 1997-1999 Chevrolet Malibu 4-cylinder 2.4L, the 1997-2003 Malibu V6 3.1L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is a downstream, direct-fit, narrow-band sensor with four wires.
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Monitors the air-fuel ratio in the exhaust gas for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases and helps reduce pollutants
Quick facts
- Part: Walker Products 350-34134 oxygen sensor
- Fits: the 1997-1999 Chevrolet Malibu 4-cylinder 2.4L, the 1997-2003 Malibu V6 3.1L and other vehicles
- Position: Downstream, downstream left, downstream right, downstream front
- Condition: New
A failing sensor can show up as poor engine running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A worn sensor may be the reason, but the wiring harness or connector can also be behind them, so look both over for physical damage with the engine off before you replace the sensor.
Fits
The 1997-1999 Chevrolet Malibu 4-cylinder 2.4L, the 1997-2003 Malibu V6 3.1L, the 1999-2001 Oldsmobile Alero 4-cylinder 2.4L and the 1999-2004 Alero V6 3.4L each take one of these sensors, and so do the 1999-2001 Pontiac Grand Am 4-cylinder 2.4L, the 1999-2004 Grand Am V6 3.4L and other vehicles.
