Walker Products 350-34253 oxygen sensor for the 1995-2000 Toyota Tacoma 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas for the ECU. Each Walker part number is made for its specific application and fitment position.
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Tracks the air-fuel ratio from exhaust oxygen content as a gauge of combustion efficiency
- Coating that guards the electrode surfaces against contamination and erosion from combustion residue and particulates
Quick facts
- Part: Walker Products 350-34253 oxygen sensor
- Fits: 1995-2000 Toyota Tacoma 4-cylinder 2.4L and other vehicles
- Position: Upstream, downstream
- Condition: New
A failed sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Those signs alone do not prove the sensor is at fault, since a vacuum leak is another common cause. The sensor, wiring harness and connector can also be inspected for physical damage.
Fits
The vehicles it fits include the 1995-2000 Toyota Tacoma 4-cylinder 2.4L, the 1999-2000 Toyota 4Runner V6 3.4L and the 1994-1997 Toyota Previa 4-cylinder 2.4L. If your car is not one of these, open the "Vehicles it fits" section and check your exact model and engine.

Frequently Asked Questions
Is this the right Toyota 4Runner oxygen sensor for a 1999-2000 V6 3.4L?
Yes. Walker Products 350-34253 is listed for the 1999-2000 Toyota 4Runner V6 3.4L, with a quantity of one per vehicle.
Is this the oxygen sensor for a 1995-2000 Toyota Tacoma 4-cylinder 2.4L?
Yes. Walker Products 350-34253 is listed for the 1995-2000 Toyota Tacoma 4-cylinder 2.4L. For any other engine or model, open the "Vehicles it fits" section.
Is this Walker Products oxygen sensor wideband or narrow-band?
Narrow-band. It is a 4-wire, direct-fit sensor with a flange mount.
Which signs can point to a failing oxygen sensor on this part?
The engine can run poorly, fuel consumption can rise, or the malfunction indicator light can come on. Newer vehicles also store fault codes in the ECU.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. A coating on the electrode surfaces guards them against contamination and erosion from combustion residue and particulates.
