This might be somewhat of a lame question; but, when a CEL is on, does the ECU adjust certain aspects of the engine's performance? I know that my friend's H22 Accord will be a turd when he throws a code because the motor disables VTEC. I'm just wondering if the Ecotec's have any kind of electronic fun police that make the motor make less power... The reason I ask is because my motor is throwing the P0113 code after my Intake install... Immediately after installing my AEM, I felt a good increase... however, it wasn't throwing a code at the time. About 20 mins after driving, it's now throwing a code and the motor seems to be running a little rough in high RPM's... is it because the sensor isn't getting enough voltage and therefore, the motor isn't dumping the correct fuel amount? (it's throwing the Intake Air Temperature High Circuit Input code) Or, is it just because it's throwing a CEL?
Let me know if that was completely incoherent...
are there alot of people that have this problem from just an intake? i figured this would be a very straightforward modification with very little problems or complications. are alot of people really having this problem?
the problem, Dan, is that the "pigtail connector" was poorly designed by GM... the connection that the wires make with the contacts inside the connector is very weak... the slightest tug on that connector (or even the constant tension put on it by stretching it out to install it in the intake) could loosen that connection which will cause the ECU to throw a code when the voltage drops...

No. If they put the IAT sensor inside the intake then they should be fine and throw no codes.

Well, problem solved... I replaced the "pigtail connector" for $23 from Chevy Dealer... didn't get a part number.... but it solved my problem. And actually, NJHK, I was throwing a code because AEM decided to put the hole on the intake too far from the wiring harness causing tension on the wire going to the IAT sensor... had AEM put the hole in the same area that the hole was on the stock intake tube, there wouldn't be a problem. Chevrolet made the length of wire going to the IAT sensor JUST long enough to make it and when installing the AEM, one has to pull it to get it to the AEM hole. Often, people pull too hard on the weak connection and loosen the wires going into the connector. simply replacing the connector and splicing the wires together solves the problem.
Just so you know, Dan, as long as you make sure there is SOME slack on the wires going from the harness to the sensor, you shouldn't have a problem... the problem arises when those wires are pulled tight and loosen from the connector...

Freakin' AEM!

Strange, normally you have enough wire to put it on the CAI...
