Walker Products 350-341090 right oxygen sensor for the 2018-2021 Toyota Tundra V8 5.7L and other vehicles measures the oxygen in the exhaust gas. It is made for its specific fitment position and gives the ECU the diagnostic feedback it requires.
- 4-wire, narrow-band design
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
Quick facts
- Part: Walker Products 350-341090 oxygen sensor
- Fits: 2018-2021 Toyota Tundra V8 5.7L and other vehicles
- Position: Downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light. Before replacing it, look over the sensor, wiring harness and connector for physical damage with the engine off and cool, because damage there can also shorten a sensor's life.

Frequently Asked Questions
Will this Toyota Tundra oxygen sensor fit a 2018-2021 Tundra V8 5.7L?
Yes. Walker Products 350-341090 is the downstream right oxygen sensor for the 2018-2021 Toyota Tundra V8 5.7L, and it also fits the 2018-2022 Toyota Sequoia V8 5.7L.
Is the Walker Products 350-341090 an upstream or downstream sensor?
This Walker Products 350-341090 sensor is a downstream right sensor. That position takes one, and the other side is a separate part.
What does this Walker Products oxygen sensor measure?
This oxygen sensor measures the oxygen content of the exhaust gas to monitor the air-fuel ratio and combustion efficiency. It is a 4-wire narrow-band sensor.
Does a bad oxygen sensor set a fault code on newer vehicles?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read them to help find the cause.
What thread size does the Walker Products 350-341090 use?
The Walker Products 350-341090 oxygen sensor has an M18 - 1.5 thread.
