SOURCE: the overhead outdoor temperature Gage reads 25-75

The outdoor temp sensor is just inside the grill when you opent the hood. The part cost around $76 and kind of looks like a electrical plug receptacle. There are little clips holding the old one in that need to be held apart to dislodge it, slip the new one in, and you're done. Took about 5 minutes.

Good luck!

The sensor is located near the hood latch area in front of the radiator. If the temp is reading incorrectly, chances are it is defective. You can purchase a new one, they relativly inexpensive.
Disconnect the electrical connector then remove the sensor.
Good luck, let me know.
Regards,

SOURCE: Outside temperature reading on my 2009 Chevy

the outside temperature sensor on vehicles takes the temperature of the air about 2-3 inches off the ground, that close to the ground it might be a couple degrees colder than the temperature on the thermometer you have mounted in the window of your house.

Coolant temperature sensor location on 97 ford expedition


I believe they are located in the intake manifold somewhere. Make sure the one that tells the computer the coolant temp is ACTUALLY giving out the correct temperature. I had a bad one one time in a 1993 Ford F-150, 5.8L....... no check engine light came on but hard to start. The bad sensor was telling the computer it was 32 degrees F when it was almost 80 degrees outside.!!
Garbage in=Garbage out.

Here is a video link from Youtube. There are 2 sensors, 1 for the guage and the other tells the on-board computer how hot/cold the coolant is. The one for the guage has 1-wire and the other one has 2 wires.
Hope this helps, ask more if you need to. What kind of problem are you having? No heat inside? Guage needle not getting into the normal area?

I have a mazda mpv 2002. Fans do not work unless the ac is on. Changed the cfm and still the same. Could cooling temp sensor be not signalling the module while still operating normal temperature readings


The fans will not come on till the temperature is above about 90 degrees so it sounds like yours is working ok! The fans will come on as soon as the AC is turned on!

A/c recharge what is thew psi for refrigerant


Below are normal car AC pressure readings with 134A.

Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI

Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI

Normal high side reading ranges from 200-350 PSI
Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience.

If normal gauge readings are obtained and the vent air is cold – STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system.

Thank you for using fixya and be safe.

2002 ford expedition


THIS IS DEPENDENT ON AMBIENT AIR TEMPERATURE , THAT IS TEMP OUTSIDE NEED TO GET TEMPERATURE PRESSURE CHART TO DETERMINE THIS NUMBER , ALSO LOW SIDE OR HIGH SIDE , LOW SIDE PRESSURE IS THE ONE I USUALLY USE TO ADJUST CHARGE , BUT AS I SAID IT IS DIRECTLY RELATED TO AMBIENT AIR SO THERE IS NOT A GIVEN NUMBER SHOULD BE ABLE TO GET CHART @ AUTO SUPPLIER OR JUST ASK ONE OF YOUR AC PEOPLE IF THEY CAN MAKE YOU A COPY OF ONE .
