Walker Products 350-31015 oxygen sensor for the 1981-1983 Ford F-150 6-cylinder 4.9L, the 1981-1985 F-150 V8 5.0L or 5.8L and other vehicles measures the oxygen content of the exhaust gas. It is a direct-fit, narrow-band sensor, and its readings help fine-tune the air-fuel mixture for fuel economy.
- Made for its specific application and position, with the diagnostic feedback the ECU requires
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Coating helps protect the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors the air-fuel ratio for combustion efficiency
Quick facts
- Part: Walker Products 350-31015 oxygen sensor
- Fits: 1981-1983 Ford F-150 6-cylinder 4.9L, the 1981-1985 F-150 V8 5.0L or 5.8L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A worn sensor can show up as poor running, higher fuel use or a lit malfunction indicator light, though the wiring harness or the connector can be behind the same signs, so inspect both for physical damage too. Newer vehicles store fault codes in the ECU, and some relate to the sensor.
Fits
The 1980-1986 Ford Mustang 4-cylinder 2.3L, the 1981-1982 Mustang V8 4.2L, the 1984 Mustang V8 5.0L, the 1984-1986 Mustang V6 3.8L, the 1981-1983 Ford F-250 6-cylinder 4.9L and the 1981-1985 F-250 V8 5.0L or 5.8L all fit this oxygen sensor, and so do many other vehicles.

Frequently Asked Questions
Is this the right oxygen sensor for a 1981-1985 Ford F-150 V8 5.8L?
Yes. Walker Products 350-31015 fits the 1981-1983 Ford F-150 6-cylinder 4.9L and the 1981-1985 F-150 V8 5.0L or 5.8L. Look up any other car in the "Vehicles it fits" section.
Is this the right oxygen sensor for a 1984-1986 Ford Mustang V6 3.8L?
Yes. The fitment lists the 1984-1986 Ford Mustang V6 3.8L, with a quantity of one sensor for that application.
Is this oxygen sensor narrow-band or wideband?
This Walker Products 350-31015 is a narrow-band oxygen sensor. Its electrodes are made of a gas-permeable platinum layer.
Does this oxygen sensor give the ECU the diagnostic feedback it needs?
Yes. Each Walker Products 350-31015 is made for its specific application and fitment position, so it supplies the relevant diagnostic feedback the ECU asks for.
What does the coating on this oxygen sensor protect against?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates carried in the exhaust gases.
