Walker Products 350-34493 oxygen sensor for the 1998 Nissan Quest V6 3.0L, the 1999-2000 Quest V6 3.3L and other vehicles measures the oxygen content of the exhaust gas. Working in the downstream position, it monitors the air-fuel ratio for combustion efficiency and gives the ECU the diagnostic feedback it needs.
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Narrow-band design with 4 wires
Quick facts
- Part: Walker Products 350-34493 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 failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. A vacuum leak, an exhaust leak, a misfiring spark plug or a damaged wiring harness or connector can be behind those signs too, so find the cause before you buy a sensor.
Fits
This sensor is a direct fit for the 1998 Nissan Quest V6 3.0L and the 1999-2000 Quest V6 3.3L. It is also a Mercury Villager oxygen sensor for the 1999 model with the V6 3.3L. This listing is one sensor, and the fitment calls for one in the downstream position.
