Walker Products 250-241118 oxygen sensor for the 2003-2004 Dodge Ram 1500 V8 4.7L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a narrow-band, 4-wire direct-fit unit that monitors the air-fuel ratio for combustion efficiency.
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, supporting fuel economy
- Made for a specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-241118 oxygen sensor
- Fits: 2003-2004 Dodge Ram 1500 V8 4.7L and other vehicles
- Position: Downstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. An exhaust leak or a fault in the wiring harness or connector can be behind the same signs, so find the cause before buying. With the engine off and cool, look the sensor, harness and connector over for physical damage.
Fits
This oxygen sensor fits the 2003-2004 Dodge Ram 1500 V8 4.7L, the 2002-2005 Dodge Durango V8 4.7L and the 2002-2004 Dodge Dakota V8 4.7L. A 2002-2005 Dodge Durango V8 4.7L takes one sensor, and this listing is one sensor.

Frequently Asked Questions
Is this Ram 1500 oxygen sensor the right one for a 2003-2004 model with the V8 4.7L?
Yes. Walker Products 250-241118 fits the 2003-2004 Dodge Ram 1500 V8 4.7L, and it is made for a specific application and fitment position.
Does this Dodge Dakota oxygen sensor fit a 2002-2004 truck with the V8 4.7L?
Yes. The 2002-2004 Dodge Dakota V8 4.7L takes one sensor, and this listing supplies one Walker Products 250-241118 oxygen sensor.
Is this oxygen sensor narrow-band or wideband?
It is a narrow-band sensor with four wires and an M18 - 1.5 thread. Its electrodes are made of a gas-permeable platinum layer.
Can a bad oxygen sensor make the engine run poorly and use more fuel?
Yes, a failed sensor can cause poor running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Newer vehicles may also store a fault code in the ECU.
How does the coating on this Walker Products oxygen sensor protect the electrodes?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas.
