Although generic, the specific repair steps may vary depending on make/model. I've mirrored the reference PDFs and guides shared online here for everyone: You must log in or register to reply here. However, if when unplugging the IAT, the reading doesn't change then turn off the ignition and disconnect the PCM connector. my guess is it's under the front bumper bar. temperature. In order to safely and efficiently replace your IAT sensor, you will need a couple of basic tools. November 2012. GM sends a 5 V reference signal and a ground signal from the computer. Hot air is less dense than cold air, so each type of environment requires a specific air/fuel mixture. If the engine is cold, the IAT reading should be the same as the CTS (Coolant temperature sensor) reading. The only thing that can cause the engine to start with Hi there.

There should be some resistance, so if it measures infinite resistance, replace the sensor. Just had another look at mine, as far as I can tell, the sensor on the end of the intercooler measures temperature after the air has passed through the intercooler as the hose leads towards the inlet manifold on the front of the engine which is where the throttle body is located. Racing & Performance Catalogue from Premier Auto Trade. Two wires feed the sensor a 5 V reference signal and ECM ground. Using the simple two wire set up found on most General Motors automobiles diagnosis is straightforward. The good news is diagnosing and repairing intake air temperature sensor issues is fun compared to some of the other automotive computer and sensor failures you could have.As an example, I just finished an article about fuel tank pressure sensor replacement on GM cars. Thankfully IAT sensors remain in the top five of the easiest computer input sensors to replace on any automobile.With that said, although this sensor most often becomes the cause of a check engine light complaint, there's a possibility of a wiring problem.
