check engine light with PRM intake

[sheller]

My check engine light has been coming on and when I had it hooked up to the computer it said the cause was too warm of air coming into the intake. I have a PRM intake with the metal tube directed into the fender area. The thing that baffles me is that the light comes on not only after the car is warm but when the rpm's are consistently over 3000...generally on the freeway at cruising speed (55-65). Why would then be the time that the air gets too warm? It seems like there would be more than enough airflow to keep it cool. Has anyone encountered this before? I need to take my car through DEQ and they won't test it if there is a warning light on.

did you try resetting your ECU? When ever you get an aftermarket intake you have to reset your ECU. This may or may not help, but my friend who has a 2003 Lancer put a AEM intake on and it sucked *ss at first, but then we just disconnected the ground from the battery for 30 seconds and then cranked the car up and she ran like a beauty! Its something to do with the MAF. Hope this helps.

Well, I have the code reset according to the instructions. I've also had some stereo work done since then (an amp as well as a powered sub...both done at different times) so I believe the battery has been disconnected for more than 30 seconds. Is there something else that has to be done to reset the ECU?

Not always necessary, but this makes sure: With the battery disconnected, hold the brake pedal down for 30 sec, to ensure the ECU is fully discharged.

However, if you're getting Code 10, it could be a problem with the connector or the wiring to the thermosensor (built into the VAF) or the sensor itself. If it always happens with the revs above 3000 it could be either vibration, or engine movement on the mounts putting strain on the connections.
