Default 1999 F-150 strange overheating problems

Hello Everyone,

I own a old 1999 F-150. I have taken it into ford dealer several times: to have them fix the odometer, which they never did. After awhile the temp gauge goes high,and then the truck runs rough.I took it into a guy named Robert last time when the truck did this, and he checked the temp of the engine, and it was not hot enough to overheat, he told me it was under 200.

Robert thinks there is something wrong with my dashboard, which is sending wrong codes to the ECM, which in return is putting it into some kinda safe mode, which makes it run rough.

I have also noticed it also only happens when I run my air conditioner.

So does anyone have any suggestions on how to fix this problem.

You may be able to pull some codes from the computer to point you in the right direction. This can be done for free at Auto Zone.

If you don't already own a Ford (or Ford owned product), get one.

Thanks for the idea Bullitt94,

But Robert has already done that. And he cant seem to figure it out either. He has one of those machines that hooks up to the truck and shows all the codes.

Any other Idea's?

Has your mechanic checked to see what the temp. sensor is reading? If it has failed closed, the ECM could be doing it. See if he can read the PIDs and post back. If you can get the readings of the sensors posted when it is showing the overheat condition, we can help you.

hello way2old,

I dont understand what your saying.Can I find this out if I go to a auto zone? I dont know a lot about trucks, I just drive them, and put gas in them. I leave the messing around with cars or trucks to people that are good at it. My body and skin doesnt do good with grease or oil on it.

No, it happened: then he looked at it.

To me it sounds electrical: because my odometer works sometimes, not always.

Because robert looked all over my engine, and everything looks fine: is what he said.

I even replaced the thermostate, with a new one from ford.

Well we took out the C.B. And so far it has happened, so it has nothing to do with the C.B. Next would like to see if it has anything to do with XM-Radio. Robert thinks its the display panel which has been acting strange lately anyways.

I remember the last time the truck said it over heated, well right after it happened, Robert told me to drive another 5 miles then pull over and pop open the hood, and check the temp, and see if anything was boiling. Well I did and nothing was boiling over, and the engine wasn't even hot.

So we think its something electrical
