Causes and Symptoms of a Bad Intake Air Temperature (IAT ...

+

Shake the IAT sensor connection to the mass air flow sensor, and check to see if there is any difference in reading. A change in the reading indicates a bad connector, which then has to be replaced. If the temperature reading displays 30 to 40°F, the dashboard light should show the code P0113, and if the reading displays 300°F, the ...

MAF, MAP, and IAT Sensors

+

The MAF or Mass Air Flow sensor (if present) is the main sensor used by the ECM to determine Fuel Delivery. MAF sensors usually consist of a tube that may or may not contain passages but all types contain some kind of sensing element.

MAF Sensor/Mass Air Flow Sensor

+

The MAF sensor is used to measure the mass flowrate of air entering the engine. This measurement is used by the car computer to establish the amount of fuel to add to provide an optimal combustion. MAF Sensor The MAF (Mass Air Flow) sensor is fitted to the inlet after the air filter box and before the throttle body.
