i dont know what wrong wit my tc... when i drive the car the check indicator is on
is it because of changing to trd muffler???? do there any solution for that??? thank alot pal for d answer...

 

My brain hurts from reading some of that..

Anyway, I'm assuming you mean the CEL? Did you buy the car used? Did you put anything other than the TRD exhaust on? Need a little more info before anyone can help you with your problem...

 

yes... i buy used car..... i don't know what's wrong... after i change to trd exhaust the check engine indicator turned on.... what do i have to do???? i called one of my friend, and he said that i have to put some kind of sensor... but i'm not sure bout dat... i change trd exhaust and avic d3.... thx

 

A sensor because of the TRD exhaust? eh? Sorry but your friend doesn't sound like he really knows what he's talking about and the only sensor I can think of him reffering to is an o2 sensor but the TRD exhaust doesn't go anywhere near either of our o2 sensors so there shouldn't have been a reason for messing with it, unless it was already gone when you bought the car which I highly doubt if the CEL came on AFTER you installed the exhaust.

I doubt the Avic D3 can cause a CEL (I may be wrong but unless you seriously somehow screwed up something in your electrical system I don't see it throwing a code like that..)

I say take it to auto zone and have them use a scan tool to see what code it's throwing. The TRD exhaust shouldn't cause anything like that especially since it's just an axle-back. Make sure you check the quality of your install and that everything is bolted up properly.
