Walker Products 250-24944 oxygen sensor for the 2001-2003 Dodge Grand Caravan V6 3.3L or 3.8L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine is burning fuel. Every Walker Products oxygen sensor is made for its specific application and fitment position, and sends the diagnostic feedback the ECU expects.
- Measures oxygen content in the exhaust gas to monitor the air-fuel ratio
- Oxygen readings are used to fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 250-24944 oxygen sensor
- Fits: 2001-2003 Dodge Grand Caravan V6 3.3L or 3.8L and other vehicles
- Position: downstream, upstream rear, upstream front, downstream front, downstream rear
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, though other faults can produce these signs too. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage, and have any stored codes read before you replace the sensor.

Frequently Asked Questions
Is this the O2 sensor for a 2001-2003 Dodge Caravan with the 4-cylinder 2.4L or V6 3.3L?
Yes, Walker Products 250-24944 fits the 2001-2003 Dodge Caravan with the 4-cylinder 2.4L or V6 3.3L. For another vehicle, look up your own year and engine in the "Vehicles it fits" section.
Is this a replacement oxygen sensor for the 2001-2003 Dodge Grand Caravan V6 3.3L or 3.8L?
Yes, Walker Products 250-24944 fits the 2001-2003 Dodge Grand Caravan with the V6 3.3L or the V6 3.8L. The listing is one sensor.
How many wires does the Walker Products 250-24944 oxygen sensor have?
Walker Products 250-24944 is a 4-wire, narrow-band, direct-fit oxygen sensor.
What can a failing oxygen sensor do to the way my engine runs?
It can lead to rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Newer vehicles store fault codes that may relate to the sensor and its associated systems.
What are the electrodes on this oxygen sensor made of, and what protects them?
The electrodes are made of a gas-permeable platinum layer. A coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
