Walker Products 250-23007 oxygen sensor for the 1987 Ford F-150 6-cylinder 4.9L, the 1987-1990 F-150 V8 5.0L, the 1988-1989 F-150 V8 5.8L, the 1989 F-150 6-cylinder 4.9L and other vehicles measures the oxygen left in the exhaust gas. This Walker Products oxygen sensor is a 3-wire, direct-fit, narrow-band unit for the upstream position.
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels to fine-tune the air-fuel mixture for fuel economy
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases and helps reduce pollutants
Quick facts
- Part: Walker Products 250-23007 oxygen sensor
- Fits: 1987 Ford F-150 6-cylinder 4.9L, the 1987-1990 F-150 V8 5.0L, the 1988-1989 F-150 V8 5.8L, the 1989 F-150 6-cylinder 4.9L and other vehicles
- Position: Upstream
- Condition: New
A failing oxygen sensor can lead to rough running, higher fuel consumption or a lit check engine light, and a fault elsewhere in the engine or exhaust can look the same. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage before you replace the sensor. Each engine takes a single upstream sensor, and this listing is one.
Fits
The 1989-1992 Ford Ranger V6 2.9L and the 1987-1989 Ford F-250 6-cylinder 4.9L take this sensor too, and so do other Ford and Mercury trucks, vans and cars.
