Walker Products 250-24401 oxygen sensor for the 1998-2004 Nissan Frontier 4-cylinder 2.4L and other vehicles measures the oxygen content of the exhaust gas. This downstream Walker Products oxygen sensor gives the ECU the diagnostic feedback it needs.
- Measures oxygen in the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating guards the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes with a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24401 oxygen sensor
- Fits: 1998-2004 Nissan Frontier 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. Before you replace the sensor, rule out a damaged wiring harness or connector by looking them over with the engine off and cool, and have any stored fault codes read, because those signs can come from other causes.
Fits
It is listed for a wide range of Nissan models, including the 1996-2001 Nissan Sentra 4-cylinder 2.0L, the 2005-2008 Nissan Urvan 4-cylinder 2.4L and the 2008-2013 Urvan 4-cylinder 2.5L. The listing is a single sensor, and these vehicles need just one in this position.

Frequently Asked Questions
Is this the right oxygen sensor for a 1996-2001 Nissan Sentra 4-cylinder 2.0L?
Yes. Walker Products 250-24401 is listed for the 1996-2001 Nissan Sentra 4-cylinder 2.0L as a downstream sensor. If your car is not named on this page, look it up in the "Vehicles it fits" section.
Will this oxygen sensor work as a replacement for the 1998-2004 Nissan Frontier 4-cylinder 2.4L?
Yes. This downstream sensor is listed for the 1998-2004 Nissan Frontier 4-cylinder 2.4L, and that application takes one sensor, which is what this listing supplies.
Is this downstream oxygen sensor narrow-band or wideband?
It is narrow-band. Walker Products 250-24401 is listed as a narrow-band sensor with 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 or exhaust emissions, or light the malfunction indicator light. A shop can read the stored fault codes.
How does the coating on this oxygen sensor protect it?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust. The electrodes carry a gas-permeable platinum layer.
