Walker Products 350-34607 oxygen sensor for the 2001 Nissan Pathfinder V6 3.5L and other vehicles measures oxygen in the exhaust gas. It is made for the downstream right, downstream rear position and gives the ECU the diagnostic feedback that position calls for.
- Measures the oxygen content of the exhaust gas to monitor the air-fuel ratio
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Narrow-band, 4-wire direct-fit design built for its specific fitment position
Quick facts
- Part: Walker Products 350-34607 oxygen sensor
- Fits: 2001 Nissan Pathfinder V6 3.5L and other vehicles
- Position: Downstream right, downstream rear
- Condition: New
A failing sensor can show up as the engine running poorly, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone don't prove the sensor is at fault, since a vacuum leak can produce a similar picture. Once the exhaust has cooled, look over the sensor, wiring harness and connector for physical damage.
Fits
The 2001 Nissan Pathfinder V6 3.5L, the 1998-2001 Nissan Maxima V6 3.0L and the 1999-2001 Infiniti I30 V6 3.0L all take this sensor, and so do other vehicles. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Will the Walker Products 350-34607 work as a Nissan Maxima oxygen sensor on a 1998-2001 Maxima V6 3.0L?
Yes. The Walker Products 350-34607 fits the 1998-2001 Nissan Maxima V6 3.0L in the downstream right, downstream rear position, one per vehicle.
Is this a 2001 Nissan Pathfinder oxygen sensor that fits the V6 3.5L engine?
Yes. The Walker Products 350-34607 is listed for the 2001 Nissan Pathfinder V6 3.5L, in the downstream right, downstream rear position.
Is this oxygen sensor narrow-band or wideband?
Narrow-band. It has a 4-wire design and an M18 - 1.5 thread.
Can a failing downstream rear oxygen sensor turn on the check engine light?
Yes, a failed sensor can light the malfunction indicator light. Newer vehicles also store fault codes in the ECU, some tied to the sensor, and a shop can read them.
What protects the electrodes on this Walker Products oxygen sensor?
A coating keeps combustion residue and particulates in the exhaust gas from contaminating or eroding the electrode surfaces. The electrodes are a gas-permeable platinum layer.
