Walker Products 250-24631 right oxygen sensor for the 2001-2002 Mitsubishi Montero V6 3.5L, the 2003-2006 Montero V6 3.8L and other vehicles measures the oxygen content of the exhaust gas. It sends the ECU the reading it uses to monitor the air-fuel ratio and combustion efficiency.
- Narrow-band design with four wires
- Electrodes made of a gas-permeable platinum layer
- 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
- Built for its specific application and position on the vehicle, with the diagnostic feedback the ECU requires
Quick facts

Frequently Asked Questions
Is this a Montero oxygen sensor for the 2003-2006 Mitsubishi Montero V6 3.8L?
Yes. Walker Products 250-24631 fits the 2003-2006 Mitsubishi Montero V6 3.8L and the 2001-2002 Montero V6 3.5L, in the upstream right position.
How does this Walker Products oxygen sensor track combustion?
Walker Products 250-24631 determines the oxygen content of the exhaust gas. That lets the ECU monitor the air-fuel ratio for combustion efficiency.
Is this oxygen sensor narrow-band, and how many wires does it have?
Yes, this oxygen sensor is a narrow-band design with 4 wires and an M18 - 1.5 thread.
What does the coating on this oxygen sensor protect?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes use a gas-permeable platinum layer.
Is the 250-24631 sold as one sensor for the upstream right position?
Yes, this listing is one oxygen sensor for the upstream right position, which takes one; sensors for other positions are separate parts.
