I recently bought an AEM cold air intake from a member on this forum for my 03 corolla le. The intake is supposed to fit an 03-04 corolla but for some reason I got a check engine light. I tried switching the mass air flow sensor for the one that came with my stock air box but nothing happened. I then removed my battery for 10 minutes and put it back on. It got ride of my check engine light for a couple of days but then the light came back on. Anyone else on here ever experience this problem? My car is running perfectly fine but ill go & get it diagnosed just for peace of mind.

Not the original adapter or filter but as far as I know that shouldn't cause a problem.

Pull the code? Do you mean to program the ecu?
I'm pretty sure. What color is it?

When the CEL comes on its best to use a OBDII reader to get the CEL code. So it can be easier to pinpoint the issue
the EVAP is where the green cap is on the first pic.

My friend plugged in his diagnostic machine to check what was wrong but it wouldn't work. Not sure why but it did not active at all.
yeah that tube is connected to the intake. I'll check it to see if its on tight though.

Are you certain that the intake isn't for an xrs? because we can run the xrs intakes but it will cause a check engine light to go of, happened to me so it's possible

Get some MAF Sensor Cleaner and clean your MAF
Get some Throttle Body Cleaner and clean your throttle body

make sure the intake tube it attached tightly to the intake manifold with the rubber coupler, even a slight gap can cause a CEL

Without the code from the ECU it's hard to say what the problem is. More than likely you have an air/vac leak somewhere. Installing CAIs/SRIs seems to expose these issues especially with the intake mainfold gasket that has been a problem with the 03-05 1zz engines.

Get a can of CARB cleaner, with the engine idling, spray around your CAI, TB, and VAC connections then the Intake Mainfold gasket. When you hear the engine idle change you found the leak. The mainfold gasket is a $30 part, and will take about 1 hour to replace.

It shouldn't be the intake man. I installed an Xrs intake on a 04 CE and it worked perfectly. Good luck... Make sure to clean the MAF.

I tried diagnosing it but when I plugged in the OBDII it would not read my ecu. Think I might have a blown fuse or something?

Was the car running? Or at least have the ignition in the ON position?

there are several issues witht he AEM intake provided every thing is hooked up properly. one being loose or leaking vacuum hose on the nipple. there is also if there is excess vibrations that shows a leaking gasket on the IM. there is also gasket issues with MAF while in the maf holder on the intake. If i had to bet money it would be the o-ring on the maf needing to be replaced.

I will check for all of the thing mentioned on the intake.
As far as the ecu. I tried it all and the OBDII would not read it.
