Walker Products 350-31029 oxygen sensor for the 1984-1985 Chrysler Town & Country 4-cylinder 2.6L and other vehicles measures the oxygen content of the exhaust gas. This direct-fit Walker Products oxygen sensor is narrow-band and gives the ECU the diagnostic feedback it needs.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, supporting fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Tracks the air-fuel ratio to show how efficiently combustion is running
Quick facts
- Part: Walker Products 350-31029 oxygen sensor
- Fits: 1984-1985 Chrysler Town & Country 4-cylinder 2.6L and other vehicles
- Position: Upstream
- Condition: New
Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean a sensor is failing. Those signs alone do not prove the sensor is at fault, since a misfire can light the same lamp. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage. This listing is one sensor, and the engine takes a single upstream unit.
Fits
The 1984-1985 Chrysler Town & Country 4-cylinder 2.6L, the 2004-2005 Dodge H100 4-cylinder 2.4L and the 1990-1994 Subaru Loyale H4 1.8L are among the vehicles this oxygen sensor fits, along with many more. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this the right oxygen sensor for a 1984-1985 Chrysler Town & Country 4-cylinder 2.6L?
Yes. Walker Products 350-31029 is listed for the 1984-1985 Chrysler Town & Country 4-cylinder 2.6L, which takes one sensor.
Is the 350-31029 an upstream or downstream oxygen sensor?
Upstream. Walker Products 350-31029 is a narrow-band direct-fit sensor listed for the upstream position.
Is this oxygen sensor narrow-band or wideband?
Narrow-band. The electrodes are made of a gas-permeable platinum layer, and the sensor determines the oxygen content of the exhaust gas.
Can a failing upstream oxygen sensor turn on the check engine light?
Yes. A failed sensor can cause rough running, higher fuel use, more exhaust emissions or a malfunction indicator light, and newer vehicles store related fault codes in the ECU.
Does CTK-OSCH1001 cross to this oxygen sensor?
Yes. CTK-OSCH1001 is an interchange number for Walker Products 350-31029.
