Check Engine!!

[RicanCelica]

Hey I got a Gen 6 Celica(2000 GT) and its coming out with the check engine ligth out of nowhere, somebody told me is the short ram intake I installed but that has been there for 2 months already and did not gave me any trouble before, do you guys think that is it or could it be something else common on this 6th Gen Celicas?

First of all, you have a gen 7 celica. Second I'd like to add that I have a gen 5 celica w/ a short ram intake also. I get a check engine light when driving highway speeds up hill only. then it turns back off. Are you having a similar problem?

[Noobified]

Getting a tune or stand alone ECU will solve the prob most likely. It has to do with the fact you are changing the diameter of the intake vs stock. Trust me, it caused the same thing on my mazda, off and on as you described. When you change the size of the intake, your changing what the maf sensor is set to detect maps for. adding air without changing certain perameters cause confusion, making the light come on. mine came on at idle though. usually at drive throughs where I idle for a long period of time.

One of the cures is to put a choke point, before the MAF sensor that was the same size as the stock intake tubing. It counters the full effects of the short/cold air intake though... If you want more details, pm or tell me.

Thank you all for your help and yes my bad I just realized is a 7th Gen because I have another account on other Forum and they had the 7th Gen with a pic of my car
Anyway I disconnected the battery from my car(reset the Computer) and the ligth is gone so lets see if it comes again.

if it was a clean install there should be no check engine.
what kind of intake?

[RicanCelica]

The intake is BOMZ short Ram Intake, and I only eliminated one sensor that is located on the actual box the rest is intact, I ask the seller before I purchased it and they told me that it was 100% good to go, so lets hope is not the intake.
