Question about 2005 Ford F-150

1 Answer

Onboard Temp gauge

My onboard temp gauge on my climate control starts off at like 90 degrees and then slowly goes down as you start driving. I know for a fact it's not 90 degrees outside right now. It's more like 20 degrees. Any ideas on how to fix this to get it working properly again. I have a 2005 Ford 500 if that helps.

Thanks!

This probably occurs when you start up after the engine has been off for a few hours. What is happening is that the module is taking a new temp reading however heat from the radiator is causing the sensor to read a warmer value than it really is. I suggest that you relocate the temp sensor further away from the radiator and closer to the grill opening in order to read actual ambient temp (approx 6" should work).

SOURCE: onboard temp gauge

you need to go to the parts house and purchase an ambient temperature sensor. that is the sensor that tells the car what the outside temp. is. I hope that helps you out.

I would check the thermostat first. Remove the thermostat and place it in a pan of water on the stove. Place a thermometer in the water with the thermostat and slowly increase the temperature until you have reached 194 degrees Fahrenheit or 90 degrees Celsius. Watch closely for the thermostat to open slightly. If it opens then the thermostat is good. If it does not open, replace it. Try that first and see what you come up with.

u have a problem with the BCM, (body control module), you will need to have the dealer scan the module for the fault, you can't just replace it because it must be programmed to your car built in security system and whatever accessories u have, also the temp gauge is ok as long as it updatede to within 2 degrees of outside temp.

My mechanic in our town did a quick computer check. Car computer indicated a low level of antifreeze, he topped it up, cleared all messages off the car computer and said to watch the the heat guage for any further irregularities. I'll keep an eye on it, love the car, great mileage fun to drive.

Does your direction work ok? I have seen that if you reset the compass then this will correct the temp problem. If not you can try disconnecting the battery for approx a min and this should reboot the system. If this don't work let me know and I can try to how you fine the fault.

Overheating when outside temp goes above 90 degrees F


on GM vehicles they still use clutch fans and when sitting at an idle for a while the fan is not pulling enough air through the radiator and condensor so therefor the a/c starts to put out warmer air and the coolant temp. will rise a little bit. You could try replaceing the fan clucth and see if that helps any.
