Walker Products 250-24235 oxygen sensor for the 1994-2002 Mitsubishi Montero V6 3.5L, the 1995-1996 Montero V6 3.0L, the 2003-2006 Montero V6 3.8L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. The Walker Products oxygen sensor is a narrow-band unit that sends the ECU the diagnostic feedback it expects.
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes coated with a gas-permeable platinum layer
- Platinum coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates
- Each part number is made for its specific application and its position on the vehicle
Quick facts
- Part: Walker Products 250-24235 oxygen sensor
- Fits: the 1994-2002 Mitsubishi Montero V6 3.5L, the 1995-1996 Montero V6 3.0L, the 2003-2006 Montero V6 3.8L and other vehicles
- Position: Upstream, downstream, upstream front, upstream rear, downstream rear, upstream right, downstream left, downstream right
- Condition: New
A failing sensor can show up as an engine that runs poorly, higher fuel consumption or a lit malfunction indicator light. A vacuum leak can also make an engine run rough, so the sensor is not the only suspect. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage. This listing is one sensor, and the fitment calls for one per application.
Fits
Besides the Montero runs above, it fits the 1997-1999 Mitsubishi Montero Sport 4-cylinder 2.4L, the 1997-2003 Montero Sport V6 3.0L and the 1999-2004 Montero Sport V6 3.5L, plus the 1999-2004 Mitsubishi Diamante V6 3.5L. If your car is not named here, look up your year, model and engine in the "Vehicles it fits" section before you order.

Frequently Asked Questions
Is this Montero oxygen sensor right for the 1994-2002 Mitsubishi Montero V6 3.5L?
Yes. Walker Products 250-24235 is listed for the 1994-2002 Mitsubishi Montero V6 3.5L. For other years and engines, use the "Vehicles it fits" section.
Is the Walker Products 250-24235 sensor narrow-band or wideband?
Walker Products 250-24235 is a narrow-band oxygen sensor. It reads the oxygen in the exhaust gas to gauge combustion efficiency.
What are the electrodes on this oxygen sensor made of?
The electrodes carry a gas-permeable platinum layer. That coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
Can a failed oxygen sensor raise fuel use?
Yes, it can. A failed sensor might make the engine run poorly, raise fuel consumption or light the malfunction indicator light, and a shop can read any stored fault codes.
Is this oxygen sensor made for a specific sensor position?
Yes. Every Walker Products part number is made for its specific application and its position on the vehicle, and the sensor supplies the diagnostic feedback the ECU needs.
