Walker Products Oxygen Sensor P/N:250-54046
Walker Products 250-24231 oxygen sensor for the 1995-1999 Mitsubishi Eclipse 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to show combustion efficiency. The Walker Products oxygen sensor is a direct-fit, narrow-band unit.
Rough running, higher fuel use or a lit malfunction indicator light can mean the sensor is failing. A different fault could be behind any of these, so look over the sensor, its wiring harness and its connector for physical damage, with the engine off and cool, before you replace it.
This direct-fit oxygen sensor also fits the 1995-1998 Eagle Talon 4-cylinder 2.0L and the 1991-1995 Dodge Stealth V6 3.0L. This listing is one sensor, and the 1995-1999 Mitsubishi Eclipse 4-cylinder 2.0L takes one.

Will this Eclipse oxygen sensor fit a 1995-1999 Mitsubishi Eclipse 4-cylinder 2.0L?
Yes. Walker Products 250-24231 fits the 1995-1999 Mitsubishi Eclipse 4-cylinder 2.0L. If your car is not named, enter its year and engine in the "Vehicles it fits" section to see whether this number applies.
Is the Walker Products 250-24231 a narrow-band or wideband sensor?
The Walker Products 250-24231 is a narrow-band sensor with four wires and an M18 - 1.5 thread.
Does a failing 250-24231 oxygen sensor set a fault code?
Yes, it can. Newer vehicles store fault codes in the ECU, and some of them relate to the affected sensor; a shop can read them.
Does this oxygen sensor have a protective coating on its electrodes?
Yes. A coating protects the electrode surfaces from combustion residue and particulates in the exhaust gas, and the electrodes carry a gas-permeable platinum layer.
Is the Walker Products 250-24231 an upstream or downstream sensor?
This part number is listed for upstream, downstream, upstream front and upstream rear positions. The listing is one sensor, and the fitment calls for one per application.
