Walker Products 250-24344 oxygen sensor for the 2012-2015 Toyota Tacoma 4-cylinder 2.7L or V6 4.0L and other vehicles measures the oxygen in the exhaust gas to report combustion efficiency. This Walker Products oxygen sensor is a narrow-band, 4-wire direct-fit unit made for a specific application and fitment position.
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases and helps reduce pollutants
- Tracks the air-fuel ratio from the oxygen content of the exhaust gas for combustion efficiency
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates
Quick facts
- Part: Walker Products 250-24344 oxygen sensor
- Fits: 2012-2015 Toyota Tacoma 4-cylinder 2.7L or V6 4.0L and other vehicles
- Position: Downstream, downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a check engine light. Those signs alone do not prove the sensor is at fault, since an exhaust leak can look much the same. The sensor's wiring harness and connector are also worth checking for physical damage.
Fits
It fits many Toyota and Lexus vehicles, and the list includes the 2013-2014 Toyota Tundra V6 4.0L, the 2014-2019 Tundra V8 4.6L and the 2015-2018 Tundra V8 5.7L. It also works as a Toyota 4Runner oxygen sensor for 2013-2020 models with the V6 4.0L. If your car is not named here, look it up in the "Vehicles it fits" section by year, make and model.

Frequently Asked Questions
Does the Walker Products 250-24344 work as a Toyota Tundra oxygen sensor for 2014-2019 models with the V8 4.6L?
Yes. Walker Products 250-24344 is listed for the 2013-2014 Toyota Tundra V6 4.0L, the 2014-2019 Tundra V8 4.6L and the 2015-2018 Tundra V8 5.7L.
Will Walker Products 250-24344 work as an oxygen sensor for the 2012-2015 Toyota Tacoma 4-cylinder 2.7L or V6 4.0L?
Yes. Walker Products 250-24344 is listed for both the 4-cylinder 2.7L and the V6 4.0L in the 2012-2015 Toyota Tacoma, and each takes one sensor.
Is this oxygen sensor narrow-band or wideband?
Walker Products 250-24344 is a narrow-band sensor with four wires, made as a direct-fit unit for its specific application and fitment position.
What can a worn downstream oxygen sensor cause?
It can lead to poor running, higher fuel consumption, more exhaust emissions or a check engine light. A shop can read the stored fault codes to narrow down the cause.
What does the coating on this oxygen sensor protect?
The coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces. The electrodes are made of a gas-permeable platinum layer.
