There isn't a reset for this. It shut down because it got too hot. Serious damage can happen from over heating. Like a seized crankshaft. I would check to see if it can be turned by hand first. If you can't turn it, it is dead.

Hi again,
Did the negative battery terminal removal able to reset the instrument CPU?
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.

Same problem on 2002 Montero XLS. Since manuals are impossible to
acquire, I subscribed to ALLDATAdiy.com (not as good as a Haynes or
Chilton's, but better than nothing). From there I was able to get the
resistance tolerances for the gauge sending unit and computer
temperature sending unit.
The temp gauge sender should have a resistance of 73 ohm at 176
degrees. Since the thermostat is 180, I figured once the engine warmed
up, it would be close to that value. The resistance started out at ~700
ohms and gradually dropped to 50 ohms and was still dropping. But it
had no wild fluctuations, so assumed it was ok. The computer temp
sending unit has a resistance of .26k ohms to .38k ohms. It was rock
solid at .24k.
Initially I had replaced the thermostat prior to finding this thread
regarding the CPU board problem. Now after checking the resistance, I
still wasn't confident that the gauge sending unit was ok (dropping
down to less than 50 and still dropping - who knew how the firmware was
programmed to translate that data?). Therefore, I went to Carquest and
got a new gauge sending unit. Put it in and as you can expect, the
problem is still occurring. However, the resistance value of the new
one is a rock solid 59.4 ohms. So I question the reliability of the
other unit, even though it didn't fix the problem.
AllDATAdiy also mentions a multi-function thermal sensor/switch.
Unfortunately, the site does not show where this sensor is located, so
I cannot even test.
At this point, I do not feel like taking it in to the dealership and
spending money to have my dashboard sent to Michigan (bad design in my
opinion that they can't reset/recalibrate at dealership), so I'm going
to just buy a separate temperature gauge to mount under the dash. At
least I will have peace of mind on the actual temperature. Although I
have a feeling at some point in the future I will be replacing the
circuit board in question since other gauges in the cluster will
probably begin flaking out as well.

try replaceing your temp sencer. some time they are near the goose neck or on the block ok . and see if your fan sencer is working. good luck

I HAD THE SAME PROBLEM. I TOOK THE AIR FILTER HOSE OFF THE CARBARATOR AND ADDED CARBARATOR CLEANER. PUT IT BACK ON, AND WORKED. TRY THAT.

2003 Mitsubishi Montero Limited. 97k miles. Temp gauge is erratic when actual temp is normal. How do I fix this?
