DTC P0113 IAT sensor 1 circuit high input

trouble code P0113= Intake Air temperature sensor 1 circuit high input.
can anybody tell me what is this mean and how to fix it. Also, my car is running really hot right now like it's going to overheat. The cooling fan turns on like it's supposed to but it turns off after a few seconds. It's supposed to stay on after the car is turned off but it does not...

by end of this week or begining of next i will get my service manual, once i get i'll let you know how to fix your problem.

as far overheating; check coolant level, you may need to replace thermostat.
to bring temperature down (temporary solution) you can run AC with heat on.
when AC on, you'll force cooling fan to stay on.
with heat on, you'll open additional cooling loop, coolant will go thru heat exchanger and discharge heat into cabin. i know it'll be hot in there, but its livable, for short period of time.

Thanks bro i will get my thermostat replaced sometime this week but in the meantime, i'll have my AC with heater running until i get this fixed....

coolant levet seems to be right at the MAX line and coolant temp sensor has been replaced a week ago....once again thanks for your help..

i just found out how to test IAT sensor.
sensor itself nothing but resistor that changes resistance with temperature. at room temperature (70 F) resistance of sensor should be 2500-3500 Ohms, at normal engine operating temperature (180 F) resistance should be 250-350 Ohms, if reading isn't within those numbers sensor needs to be replaced.

i still need to find out if there are any test for IAT wiring circuit.

One more thing;
Check if tube in coolant expansion reservoir is attached to the cap.
I heard story when that tube felt off and that caused overheating.

i just replaced the thermostat a minute ago but now my car won't start. It makes a clicking noise but nothing happen. Only the AC and cooling fan are running at the time....on the hand, i did spray intake cleaner inside the throttle body after replacing the thermostat...

may be your battery is weak, try to jump start it.

na i don't think it's the battery. The car doesn't crank up at all, it just making a click on the pass side of the car. All of the fuses are good to go..
