Walker Products 350-31200 oxygen sensor for the 2000 Nissan Sentra 4-cylinder 1.6L and other vehicles reads the oxygen content of the exhaust gas. This upstream sensor reports the reading to the engine computer, which uses it to manage the air-fuel ratio.
- Measures oxygen in the exhaust gas to help fine-tune the air-fuel ratio and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes coated with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Made for its specific application and fitment position to give the ECU the diagnostic feedback it needs
Quick facts
- Part: Walker Products 350-31200 oxygen sensor
- Fits: the 2000 Nissan Sentra 4-cylinder 1.6L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as the engine running poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since a worn spark plug or an exhaust leak could trigger them too.
Fits
This sensor is listed for a wide range of Nissan, Chevrolet and Mercedes-Benz models, including the 1996-2003 Chevrolet Chevy 4-cylinder 1.6L. It also works as an oxygen sensor for the 1985-1990 Nissan Pickup and the 1991-1995 Pickup 4-cylinder 2.4L. The fitment lists one sensor per vehicle. If your car is not named here, look it up by year, make and model in the "Vehicles it fits" section.

Frequently Asked Questions
Is this a Chevy oxygen sensor for the 1996-2003 Chevrolet Chevy 4-cylinder 1.6L?
Yes. Walker Products 350-31200 is listed for the 1996-2003 Chevrolet Chevy 4-cylinder 1.6L, and the fitment lists one sensor per vehicle.
Will this work as a Nissan Sentra oxygen sensor replacement in the 2000 Sentra 4-cylinder 1.6L?
Yes. It is listed for the 2000 Nissan Sentra 4-cylinder 1.6L as an upstream sensor, one per vehicle.
Is the Walker Products 350-31200 a narrow-band or wideband sensor?
The Walker Products 350-31200 is a narrow-band oxygen sensor with an M18 - 1.5 thread.
What are the electrodes on this oxygen sensor coated with?
The electrodes carry a gas-permeable platinum layer. The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
What can a failing upstream oxygen sensor look like?
Signs can include the engine running poorly, higher fuel consumption or a lit malfunction indicator light. With the engine off and cool, you can look over the sensor, wiring harness and connector for physical damage.
