Walker Products 250-24002 oxygen sensor for the 1991-1995 Jeep Wrangler 6-cylinder 4.0L and other vehicles measures oxygen in the exhaust gas to track combustion efficiency. This Walker Products oxygen sensor is made for its specific application and fitment position.
- Narrow-band design with four wires
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24002 oxygen sensor
- Fits: 1991-1995 Jeep Wrangler 6-cylinder 4.0L and other vehicles
- Position: upstream, downstream, upstream left, upstream right, upstream rear, downstream front
- Condition: New
A failing sensor can show up as an engine that runs poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. None of these proves the sensor is the culprit; a vacuum leak, for example, can also make an engine run poorly, so find the cause first. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage.
Fits
The 1991-1995 Jeep Wrangler 6-cylinder 4.0L, the 1994 Dodge Ram 1500 V6 3.9L or V8 5.2L and the 1994-1995 Ram 1500 V8 5.9L each take one of these sensors, and it is also an oxygen sensor for the 1994-1995 Dodge Ram 2500 V8 5.2L or 5.9L and many other vehicles.

Frequently Asked Questions
Is this the right Ram 1500 oxygen sensor for a 1994-1995 Dodge Ram 1500 V8 5.9L?
Yes. Walker Products 250-24002 fits the 1994-1995 Dodge Ram 1500 V8 5.9L and the 1994 Ram 1500 V6 3.9L or V8 5.2L. If your vehicle is not named here, run it through the "Vehicles it fits" section.
Is this the oxygen sensor replacement for a 1991-1995 Jeep Wrangler 6-cylinder 4.0L?
Yes. Walker Products 250-24002 is listed for the 1991-1995 Jeep Wrangler 6-cylinder 4.0L, and that engine takes one sensor.
What thread size does this narrow-band oxygen sensor have?
The thread is M18 - 1.5. This narrow-band sensor has four wires.
Can a failing oxygen sensor raise fuel consumption?
Yes, it can. A failing sensor may make the engine run poorly, raise fuel consumption or turn on the malfunction indicator light.
What protects the electrodes on this Walker Products oxygen sensor?
The electrodes are made of a gas-permeable platinum layer, and the coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
