The ECM's task is to adjust different automotive systems based on temperatures. This is the reason why your ride is outfitted with a number of temperature sensors such as the Intake Air Temperature (IAT) sensor. The IAT sensor measures the temperature of the incoming air. If your ride has a MAP sensor, the IAT is positioned in the intake air passage. It becomes a part of the MAF system on automobiles with mass air flow sensor. Unlike other sensors, the IAT sensor is easy to remove and to install so replacing a damaged stock is such a breeze. All you need is to disconnect the negative battery cable and detach the wiring harness connector from the sensor. Take the sensor out of the air cleaner outlet tube and wipe it down. Clean the area where the new IAT sensor will be installed. Put the sensor back in the air cleaner outlet tube carefully and securely. Reconnect the wiring harness connector to the sensor and attach the negative battery cable. It's that easy. So if yours is already malfunctioning, don't think twice in getting a replacement from us. You can be sure that the automotive sensors you'll get here are in excellent, new condition. Sourced from world-class manufacturers, the IAT sensors available here at Car Stuff are guaranteed authentic. Browse our catalog now and get an IAT sensor that's worth your every penny.
