My wife owns an 05 Tc. I installed an aftermarket cold air intake from ebay....you know the el-cheapo 60$ numbers. When I installed it I was pretty suprised at the hp gain and quality/fitment of the product. My problem is this. The check engine light now stays on you know (!) <---that one. Anyways my question is has anyone had this problem with the more expensive brand intakes and if so how was it resolved? The car runs fine but I just dont want that light on constantly. I took it to Auto Zone and they said it was the o2 which is in the header.....right? do I need to upgrade to aftermarket headers to fix this problem or is it simply a computer diagnostic issue? My next question is does anyone know where the sensor for the tire pressure light is located? I had Toyo Proxes put on a month or so ago and ever since the tire pressure light stays on. Unfortunately its no longer under warranty so Im on my own here. Last but not least my emergency brake light stays on at all times. When driving and everything but obviously the e-brake isnt up. Could this be a loose screw,bolt,washer,sensor etc.? Im not too good with these mechanics guys if you could help me out with a few pointers I would really appreciate it. Thanks again.

 

Its is the maf sencer on your intake more then less

 

you can reset your tire pressure light with a button in your glovebox. check the owner's guide for specific directions.

 

reddrumtc.....i saw that you just have the ram air intake on your tc. did you not have any problems with the o2 sensors or check engine light being on from that? i guess realistically i should proably go to the ram air for the sheer fact that it is a daily driven and im scared of it being water-bogged. ashiva....thanks hun but not being a smartass....i knew that one :-) i reset the tire pressure from the glovebox everytime i get in the car. i was just wondring if anyone knew where the actual sensor was located that is linked to the button in the glovebox so i can replace it accordingly. thank you though. im still struggling with e-brake though.....any thoughts?

 

No its just some of the ebay stuff u have to watch out for its not made well all the time. My intake is the weapon r with The weapon r ram air no check engine light has never came on no until I put the dc sport header on then I used spark plug defusers on it. Your e brake is lose to fix it its on the rear passenger area of the brake area. If I can help any other way I will try.

 

You should remove the negative battery terminal for over 30 seconds and let the car reset. If the CEL light returns, I'd probably get rid of the eBay intake and put the stock air box back in.

 

The tire pressure sensor on 05s are actually speed sensors. If they are rotating at different speeds, it assumes the tires must be at different PSI.

My Weapon R intake never provided any CELs. Did you make sure the MAF is snug on the pipe? Did you reset your car by unplugging the battery for 10 minutes?

 

thanks. i think im going to take that advice but the problem is that i got rid of the stock box. (buddy accidentally backed his gto over it after we installed intake). does anyone have the entire stock air intake syatem theyre willing to sell? thanks again.

I do, but not with the MAF sensor.

 

There is no o2 sensor on the intake, there is a MAF sensor. My car takes about 5 minutes for the CEL to clear itself. This symbol (!) is not your check engine light, it is your tire pressure light.
