Walker Products Oxygen Sensor P/N:250-241273
Walker Products 250-24314 oxygen sensor for the 2001-2003 Dodge Caravan 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas. It sits upstream and gives the ECU the oxygen reading it needs.
A failing oxygen sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can be behind these signs too, so find the cause before buying. With the engine off and cool, look over the sensor, harness and connector for physical damage.
It is the upstream oxygen sensor for the 2001-2003 Dodge Caravan 4-cylinder 2.4L and the 2001-2003 Chrysler Voyager 4-cylinder 2.4L.
Fit and size
Build and materials
This listing holds one oxygen sensor, and these vehicles take one in the upstream position.
Is this O2 sensor made for the 2001-2003 Dodge Caravan 4-cylinder 2.4L?
Yes. Walker Products 250-24314 fits the 2001-2003 Dodge Caravan 4-cylinder 2.4L (L4-2.4L) in the upstream position.
What does this Walker Products oxygen sensor measure?
This oxygen sensor determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency, and the ECU uses that reading to fine-tune the mixture.
What thread size does the Walker Products 250-24314 have?
The thread size is M18 - 1.5. It is a narrow-band sensor with 4 wires.
What is the coating on this oxygen sensor for?
The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.
What can a failing upstream oxygen sensor cause?
A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or light the malfunction indicator light. A shop can read the stored fault codes to see whether the sensor is involved.
