Walker Products Oxygen Sensor P/N:350-341076
Walker Products 350-32010 oxygen sensor for the 1990-1995 Mitsubishi Mighty Max 4-cylinder 2.4L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It sits in the upstream position and gives the ECU the diagnostic feedback it needs.
A worn sensor can show up as rough running, higher fuel use or a lit check engine light, and those signs can have other causes. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage before you replace anything.
This is a direct-fit replacement for the 1990-1995 Mitsubishi Mighty Max 4-cylinder 2.4L and the 1990-1993 Dodge Ram 50 4-cylinder 2.4L.

Will the Walker Products 350-32010 fit the 1990-1993 Dodge Ram 50 4-cylinder 2.4L?
Yes. Walker Products 350-32010 is a direct-fit upstream oxygen sensor for the 1990-1993 Dodge Ram 50 4-cylinder 2.4L and the 1990-1995 Mitsubishi Mighty Max 4-cylinder 2.4L.
Is this Walker Products oxygen sensor upstream or downstream?
It is an upstream sensor. This narrow-band, 2-wire unit is made for the upstream position on the vehicle.
What thread size does the 350-32010 oxygen sensor have?
Walker Products 350-32010 has an M18 - 1.5 thread.
What can a failing upstream oxygen sensor cause?
A failing sensor can make the engine run poorly, raise fuel consumption or turn on the malfunction indicator light. Newer vehicles also store fault codes in the ECU that a shop can read.
What does the coating on this narrow-band oxygen sensor do?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes also carry a gas-permeable platinum layer.
