Location of IAT Sensor

04-21-2009, 12:15 PM
I am trying to locate the IAT sensor on my 2007 HHR LT 2.4L.
Someone told me it is located with the MA sensor and the wires are tan & blue. I found 2 tan wires and no blue wires.
Do you know what wires to connect Performance Chip to?

Welcome to AF!

Don't cut your wiring up installing one of those, they do nothing. Return the thing if you can, otherwise throw it on a shelf and forget about it. All they can do is make the engine run rich, so most people think "less MPG... must have more HP". Not true. You may possibly get a very small increase initially (but not even enough to feel it), but will lose it once the PCM learns what's going on, which is a matter of minutes of driving. The only lasting effect it will have is make you waste gas and plug up the cat. If you want more HP out of it, you need to get something that actually reprograms the PCM.
