Walker Products 350-35070 oxygen sensor for the 2020-2024 Ford Explorer V6 3.0L and other vehicles measures the oxygen in the exhaust gas. This wide-band sensor is made for its specific application and position and reports to the ECU.
- Monitors exhaust gases to help reduce pollutants
- Electrodes with a gas-permeable platinum layer
- Electrode coating that prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Measures oxygen levels to help fine-tune the air-fuel ratio for fuel economy
Quick facts
- Part: Walker Products 350-35070 oxygen sensor
- Fits: 2020-2024 Ford Explorer V6 3.0L and other vehicles
- Position: Upstream left, upstream front
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a malfunction indicator light. These signs alone do not prove the sensor is the problem, because an exhaust leak can cause some of them too. Check the sensor, wiring harness and connector for physical damage with the engine off and cool.
Fits
This sensor is listed for a wide range of Ford, Lincoln and Porsche models, among them the 2020-2024 Ford Police Interceptor Utility V6 3.0L. This oxygen sensor also fits the 2020-2024 Lincoln Aviator V6 3.0L, in the upstream left, upstream front position.

Frequently Asked Questions
Is Walker Products 350-35070 a Ford Explorer oxygen sensor replacement for the 2020-2024 Ford Explorer V6 3.0L?
Yes. Walker Products 350-35070 is listed for the 2020-2024 Ford Explorer V6 3.0L. If your car is not named here, look it up in the "Vehicles it fits" section by year, model and engine.
Is Walker Products 350-35070 a wide-band sensor, and how many wires does it have?
Yes. Walker Products 350-35070 is a wide-band oxygen sensor with five wires (5-W).
What protects the electrodes on this oxygen sensor?
The electrodes have a gas-permeable platinum layer, and a coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas.
Will a failing oxygen sensor set a fault code?
Yes, it can. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems; a malfunction indicator light can be another sign.
Does this oxygen sensor have to match its position on the car?
Yes. Every Walker Products part number is made for its specific application and fitment position, and this sensor is for the upstream left, upstream front position.
