Walker Products 350-341008 left oxygen sensor for the 2016-2019 Ford Transit-150 V6 3.7L and other vehicles measures oxygen in the exhaust gas. Each part number is made for its specific application and fitment position, and it supplies the diagnostic feedback the ECU needs.
- Reads the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Electrode coating prevents contamination and erosion by combustion residue and exhaust particulates
- Narrow-band design with 4 wires
Quick facts
- Part: Walker Products 350-341008 oxygen sensor
- Fits: 2016-2019 Ford Transit-150 V6 3.7L and other vehicles
- Position: Downstream left
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light, but damage to the wiring or connector can produce similar symptoms. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage, and leave electrical testing to a shop before you replace the sensor.
Fits
This downstream left oxygen sensor also fits the 2016-2019 Ford Transit-250 V6 3.7L and the 2016-2019 Ford Transit-350 V6 3.7L. If your vehicle is not one of these, look up your year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Does the Walker Products 350-341008 fit the 2016-2019 Ford Transit-150 V6 3.7L?
Yes. Walker Products 350-341008 is the downstream left oxygen sensor for the 2016-2019 Ford Transit-150 V6 3.7L, and that side takes one.
What thread size does the Walker Products 350-341008 oxygen sensor have?
Walker Products 350-341008 has an M18 - 1.5 thread.
Is this a narrow-band or wideband oxygen sensor?
This downstream left oxygen sensor is a narrow-band design with 4 wires.
How can I tell if an oxygen sensor is failing?
Rough running, higher fuel consumption or a lit malfunction indicator light can be signs. Newer vehicles may also store a fault code in the ECU for the sensor and its related systems.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. Their coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas.
