Code P0113 2003 Ford F150 Description

The Intake Air Temperature (IAT) sensor is built into Mass Air Flow (MAF) sensor. The sensor detects intake air temperature and transmits a signal to the Powertrain Control Module (PCM). The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle. It is used by the Powertrain Control Module to assist with the calculation of idle speed, fuel mixture, and spark advance. The Diagnostic Trouble Code (DTC) will set when the PCM detects an excessively high voltage from the sensor.

Discuss the causes and fixes for P0113 2003 Ford F150 OBDII Code

  • have a engine miss at idle until you get above 1000 on tach then smooth's out, the only code is P0113

  • The P0113 code is for the Intake Air Temperature (IAT) sensor, but that sensor usually won't cause a miss, but check for intake air leaks around the sensor. The IAT sensor is integrated in the Mass Air Flow (MAF) sensor. If no leaks are found, you could try cleaning the MAF and replacing the air filter.

  • So I had these codes come up do you think if I replaced the transmission control module it would remove both codes that come up at P0741 and P0700 on my 2010 chevy Silverado. I'm in desperate need and no I have not had any problems with the way the truck has been running
