Walker Products 250-24616 oxygen sensor for the 1995 Chevrolet Cavalier 4-cylinder 2.2L or 2.3L, the 1996-2002 Cavalier 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. Each Walker Products number is made for its own application and fitment position, and it returns the diagnostic feedback the ECU expects.
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Narrow-band sensor with 4 wires
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes use a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24616 oxygen sensor
- Fits: the 1995 Chevrolet Cavalier 4-cylinder 2.2L or 2.3L, the 1996-2002 Cavalier 4-cylinder 2.4L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs can have other causes, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before you replace the sensor.
Fits
The 1995 Chevrolet Cavalier 4-cylinder 2.2L or 2.3L, the 1996-2002 Cavalier 4-cylinder 2.4L, the 1996-1998 Pontiac Sunfire 4-cylinder 2.2L, the 1996-2002 Sunfire 4-cylinder 2.4L and the 1996-1998 Buick Skylark 4-cylinder 2.4L or V6 3.1L all take this sensor, and so do other vehicles. If your car is not named here, open the "Vehicles it fits" section and check your exact model and engine.

Frequently Asked Questions
Is this Cavalier oxygen sensor right for the 1996-2002 Chevrolet with the 4-cylinder 2.4L?
Yes. Walker Products 250-24616 fits the 1996-2002 Chevrolet Cavalier 4-cylinder 2.4L, and the 1995 Cavalier with the 4-cylinder 2.2L or 2.3L.
Is this a Pontiac Sunfire oxygen sensor for the 1996-1998 4-cylinder 2.2L?
Yes. Walker Products 250-24616 fits the 1996-1998 Pontiac Sunfire 4-cylinder 2.2L and the 1996-2002 Sunfire 4-cylinder 2.4L.
Is this oxygen sensor an upstream or downstream unit?
It is a downstream sensor. It is a narrow-band design with 4 wires and an M18 - 1.5 thread.
What can a failing downstream oxygen sensor cause?
A failed sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light.
What is the coating on this oxygen sensor for?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes use a gas-permeable platinum layer.
