I have an '03 Montero Limited that I just replaced an 02 sensor on succesfully. While I was under there, I see that there are 2 sensors that would clearly be on the drivers side, one upper, one lower, both plug in on the drivers side, one underneath, and one up top near the dipstick under the hood. There is another sensor underneath, but it is smack dab in the middle of the truck underneath, but plugs in on the drivers side underneath the car, next to the "left lower".
When looking up oxygen sensors, I notice they list one for "right side, after catalyst", but I don't see one, as the closest thing I see that fits this description is in the middle of the truck and plugs in on the drivers side.
The fourth sensor there is no question about, as it is on the passenger side of the engine compartment.

The 02 sensor you refer to is the Right Bank(Bank 1) rear sensor. You have 3 converters, one on each side of the motor and the main converter under the vehicle. The front sensors control the fuel mixture and the rear sensors only monitor the converters to make sure they are working. After reading the codes for the sensors it is always a good idea to check the voltage output for each of the sensors and to compare the front and rear readings for each side. The front readings should always be switching faster than the rear sensor readings. If they switch at the same rate you have a bad converter on one of the front converters located just after the exhaust manifolds. _______________ Cargo Liners

I know for a fact that on most newer model vehicles they have sensors to check the sensors! So I would definately agree with Knox:)

I have a 2003 Mitsubishi Montero Sport all wheel drive 4 wheel drive 3.5 liter with 162000 miles on it. The radiator blew a little while ago upon replacing the radiator with a brand new one I have noticed that when placing it into gear and starting to drive after I hit 20 miles an hour the engine starts to Rev but the vehicle does not go any faster. I don't have any noise coming from the engine which leads me to believe this is a training issue I've read a lot of posts saying that Mitsubishi Transmissions require a certain kind of transmission fluid I'm not sure if the fluid in mind is correct or not I've only had the vehicle for 6 months now anybody have any ideas as to what I could look for before taking it to a shop my dad is a Mitsubishi technician he just doesn't want to deal with it

If I remember correctly, there are transmission lines that run to the radiator core, that either aren't hooked up correctly, or when hooked up there might have been loss of fluid and now a little low, or if topped back off the with incorrect fluid. Just ideas.
