Walker Products 250-23001 oxygen sensor for the 1984-1986 Ford Mustang 4-cylinder 2.3L, the 1985-1986 Mustang V8 5.0L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. This direct-fit narrow-band sensor is made for its specific application and fitment position, and gives the ECU the diagnostic feedback it requires.
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes made with a gas-permeable platinum layer
- Narrow-band type with a 3-W configuration
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
Quick facts
- Part: Walker Products 250-23001 oxygen sensor
- Fits: 1984-1986 Ford Mustang 4-cylinder 2.3L, the 1985-1986 Mustang V8 5.0L and other vehicles

- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and other faults can produce these too. With the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before you replace anything.
Fits
This oxygen sensor also covers the 1985-1986 Ford Ranger 4-cylinder 2.3L, the 1986 Ranger V6 2.9L and, as a Ford Taurus oxygen sensor, the 1986 Taurus V6 3.0L. If your car isn't named here, enter its year, model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the Ford Ranger oxygen sensor for the 1985-1986 Ranger with the 4-cylinder 2.3L?
Yes. Walker Products 250-23001 is listed for the 1985-1986 Ford Ranger 4-cylinder 2.3L and the 1986 Ranger V6 2.9L. For a different car, look it up in the "Vehicles it fits" section.
Is this the Ford Mustang oxygen sensor for the 1985-1986 Mustang V8 5.0L?
Yes. Walker Products 250-23001 is listed for the 1985-1986 Ford Mustang V8 5.0L, and the 1984-1986 Mustang 4-cylinder 2.3L takes the same sensor.
Is the Walker 250-23001 an upstream oxygen sensor?
Yes. This sensor is listed for the upstream, upstream left and upstream right positions.
Is this oxygen sensor narrow-band, and what thread does it have?
Yes. This sensor is narrow-band with a 3-W configuration and an M18 - 1.5 thread.
What are the electrodes on this oxygen sensor made of?
The electrodes have a gas-permeable platinum layer. A coating on them resists contamination and erosion from combustion residue and particulates in the exhaust gases.
