Walker Products 250-24433 oxygen sensor for the 1998 Nissan Quest V6 3.0L, the 1999-2000 Quest V6 3.3L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is a downstream sensor, made for its specific application and position so it returns the diagnostic feedback the ECU expects.
- Narrow-band sensor with four wires
- Reads oxygen levels to fine-tune the air-fuel mixture and support fuel economy
- Coated electrode surfaces resist contamination and erosion from combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24433 oxygen sensor
- Fits: the 1998 Nissan Quest V6 3.0L, the 1999-2000 Quest V6 3.3L and other vehicles
- Position: Downstream
- Condition: New
A worn sensor can show up as an engine that runs poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and any of these can have other causes. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage first, since damage there can shorten the sensor's operating life.
Fits
This direct-fit sensor fits the 1998 Nissan Quest V6 3.0L, the 1999-2000 Quest V6 3.3L and the 1999 Mercury Villager V6 3.3L. The fitment calls for one sensor per vehicle, and this listing is one sensor.

Frequently Asked Questions
Is this a Nissan Quest oxygen sensor for the 1998 V6 3.0L and the 1999-2000 V6 3.3L?
Yes. Walker Products 250-24433 fits the 1998 Nissan Quest V6 3.0L and the 1999-2000 Quest V6 3.3L, and it goes in the downstream position.
Is this a Mercury Villager oxygen sensor for the 1999 model with the V6 3.3L?
Yes. Walker Products 250-24433 fits the 1999 Mercury Villager V6 3.3L, and the fitment calls for one sensor on that vehicle.
Is this downstream oxygen sensor narrow-band or wideband?
This downstream oxygen sensor is a narrow-band type with four wires, and it measures the oxygen content of the exhaust gas.
What signs can a failing downstream oxygen sensor show?
The engine can run poorly, fuel consumption or exhaust emissions can rise, or the malfunction indicator light can come on. Newer vehicles may also store fault codes related to the sensor.
What does the coating on this oxygen sensor protect?
The coating shields the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes themselves are a gas-permeable platinum layer.
