Walker Products 250-24285 oxygen sensor for the 2001-2002 Nissan Sentra 4-cylinder 1.8L and other vehicles measures the oxygen left in the exhaust gas so combustion efficiency can be monitored.
- Determines exhaust oxygen content to monitor the air-fuel ratio
- Electrodes coated with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Narrow-band sensor with 4 wires
Quick facts
- Part: Walker Products 250-24285 oxygen sensor
- Fits: 2001-2002 Nissan Sentra 4-cylinder 1.8L and other vehicles
- Position: Downstream, downstream left, downstream right, downstream front
- Condition: New
A failed sensor can make the engine run poorly, raise fuel use and exhaust emissions, or light the malfunction indicator lamp, and newer vehicles may store a related fault code. Those signs have other possible sources too, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before you replace anything.
Fits
This sensor is listed for a wide range of Nissan and Infiniti models. It is a direct-fit oxygen sensor replacement for the 2001-2002 Nissan Sentra 4-cylinder 1.8L, and the same part number also covers an oxygen sensor for the 2001-2002 Nissan Pathfinder V6 3.5L and the 2002-2003 Nissan Maxima V6 3.5L. If your car is not named here, look up its year, model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right O2 sensor for a 2001-2002 Nissan Sentra 4-cylinder 1.8L?
Yes. Walker Products 250-24285 is listed for the 2001-2002 Nissan Sentra 4-cylinder 1.8L, with a quantity of one per application.
Is this oxygen sensor narrow-band or wideband?
Walker Products 250-24285 is a narrow-band sensor with 4 wires and an M18 - 1.5 thread.
What is the coating on this oxygen sensor for?
The electrodes carry a gas-permeable platinum layer. The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
What signs can a failing oxygen sensor cause?
The engine can run poorly, fuel consumption and exhaust emissions can rise, or the malfunction indicator lamp can come on. Newer vehicles also store fault codes in the ECU that may relate to the sensor.
Is each Walker oxygen sensor made for one specific application?
Yes. Each Walker Products oxygen sensor part number, including 250-24285, is made for a specific application and fitment position, and gives the ECU the diagnostic feedback it requires.
