Walker Products 250-24154 oxygen sensor for the 2000-2004 Toyota Tundra V6 3.4L or V8 4.7L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. It is built as an OE replacement, made for a specific application and fitment position, and returns the diagnostic feedback the ECU expects.
- Determines the oxygen content of the exhaust gas and monitors the air fuel ratio for combustion efficiency
- Monitors exhaust gases and reduces pollutants for a cleaner environment
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes with a gas-permeable platinum layer
- Measures oxygen levels to fine-tune the air-fuel mixture and support fuel economy
Quick facts
- Part: Walker Products 250-24154 oxygen sensor
- Fits: 2000-2004 Toyota Tundra V6 3.4L or V8 4.7L and other vehicles
- Position: Upstream, downstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. These signs alone do not prove the sensor is the problem; a damaged wiring harness or connector is another common cause, so look those over for physical damage too.
Fits
This sensor is listed for a wide range of Toyota and Lexus models, including the 1995-2000 Toyota Tacoma 4-cylinder 2.4L, 2.7L or V6 3.4L and, as a Toyota Sequoia oxygen sensor, the 2001-2004 Sequoia V8 4.7L. The listing is one sensor, and each application takes one. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this the right Toyota Tacoma oxygen sensor for a 1995-2000 Toyota Tacoma 4-cylinder 2.4L, 2.7L or V6 3.4L?
Yes. Walker Products 250-24154 is listed for the 1995-2000 Toyota Tacoma with the L4-2.4L, L4-2.7L and V6-3.4L engines, at one sensor per application.
Will Walker Products 250-24154 work as a 2004 Toyota Tundra O2 sensor on the V6 3.4L or V8 4.7L?
Yes. The 2000-2004 Toyota Tundra with the V6-3.4L or V8-4.7L is in its fitment, which includes 2004, and each application takes one sensor.
What type of sensor is the Walker Products 250-24154?
Walker Products 250-24154 is a narrow-band oxygen sensor with four wires and a flange mount.
What protects the electrodes on this oxygen sensor?
A coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gases. The electrodes have a gas-permeable platinum layer.
What can a failing oxygen sensor do to how the engine runs?
It can lead to rough running, higher fuel consumption or a malfunction indicator light. Newer vehicles may also store a fault code in the ECU.
