How To Replacement The Air Filter On 1998 Dodge Caravan 2.4l

The intake air temperature (IAT) sensor, otherwise known as the air accuse temperature sensor, is used by the powertrain control module (PCM) to make up one's mind the temperature (and therefore the density) of air entering the engine. Typically, the PCM sends a 5-volt reference to the IAT sensor. The IAT sensor then varies its internal resistance according to air temperature and sends a return signal dorsum to the PCM. The PCM and then uses this formation to determine fuel injector control and other outputs.

A bad IAT sensor can cause all kinds of drivability problems including a rough idle, surging, stalling, and poor fuel economic system. To supersede this part, you tin can follow the step-by-step guide below.
