Celica Forums General Discussion Exterior CEL came on

sup ppl...my CEL came on after installing my CAI.its been like 3 days since i put my CAI.i checked my maf sensor,gas lid,n all the hoses n it all seemed to be proper.i got rid of CEL by disconnecting my battery n reconnected it,but if it comes on again does it mean that something is really wrong with my car??maybe ive been running my car tooo much...

Running your car as in racing??, the CEL will come on at the service mileage point and when a sensor may be acting up.

Double check everything? How many miles are on your car?

get a readout and check the code

Get the code, could just be a loose hose.
