Walker Products 350-34007 oxygen sensor for the 2001-2003 Dodge Caravan 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas to show how well the engine is burning its fuel. This upstream sensor is made for its specific application and fitment position, and it returns the diagnostic feedback the ECU expects.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Electrodes made of a gas-permeable platinum layer
- Narrow-band sensor type with a four-wire connection
- Monitors exhaust gases and helps reduce pollutants
Quick facts
- Part: Walker Products 350-34007 oxygen sensor
- Fits: 2001-2003 Dodge Caravan 4-cylinder 2.4L and other vehicles
- Position: Upstream
- Condition: New
Before you replace this sensor, look over its wiring harness and connector for physical damage and think through other causes of rough running, since the same signs can come from elsewhere. A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or light the malfunction indicator lamp.
Fits
It fits as the oxygen sensor for the 2001-2003 Dodge Caravan 4-cylinder 2.4L and the 2001-2003 Chrysler Voyager 4-cylinder 2.4L. This listing is one sensor, and the 2.4L takes a single one in the upstream position.

Frequently Asked Questions
Is this the right O2 sensor for the 2001-2003 Dodge Caravan 4-cylinder 2.4L?
Yes. Walker Products 350-34007 is an upstream narrow-band sensor for the 2001-2003 Dodge Caravan 4-cylinder 2.4L, and the 2001-2003 Chrysler Voyager 4-cylinder 2.4L takes the same one.
What does this Walker Products oxygen sensor monitor?
Walker Products 350-34007 measures the oxygen content of the exhaust gas and monitors the air-fuel ratio, which shows how efficiently combustion is running.
What thread size does the 350-34007 sensor have?
This oxygen sensor has an M18 - 1.5 thread. It is sold as one sensor for the upstream position.
Will a failing oxygen sensor set a fault code?
Newer vehicles store fault codes in the ECU, and some of them relate to the affected sensor and its associated systems. A shop can read those codes.
Is the 350-34007 a narrow-band or wideband oxygen sensor?
It is a narrow-band sensor with four wires, made for the upstream position.
