cel came on after intake install

:
Mazda, Speed 2003.5
I put my injen cai intake on today and everything was running well. Once i turned my car off and then turned it back on my cel light came on. I'm not really to sure what could of happeded i checked all of the clamps and everything and it all seems to be intact. I reset the negative termial of the battery and it still comes on once i turn the car off and back on again. Please help! (boom07)
 
did you put the mass air flow in and hooked up? did you step on the brakes to ensure the charge was out of the system?
 
I never unplugged the maf sensor cause i was afraid of the cel light coming on. I just unhooked the tubes on each side of it and left the connecter attatched. What do you mean step on the breaks? I've drove it about 40 miles total today with normal driving
 
Check the mass air flow sensor. I'm almost willing to bet money that's it.

disconnect neg bat term. pump brakes for 10-15 sec. if you "reset" teh battery and the light came on immediately either its your MAF or you didnt actually reset.
 
what should i check for on the maf sensor? i didn't unhook the connector to it and the clamps are on tight around it. Unhook the negative terminal of the battery and step on the breaks for 10-15 seconds and then hook it back up?
 
no then try to drive it.

of course hook it back up and see what happens then :)
 
What does stepping on the breaks with the negative battery terminal unhooked do? I've never heard of it? I will surely give it a shot tho
 
releases the last of the electrical charge. it makes a difference trust me. if i dont do that my CEL wont clear.
 
double check your intake air temp sensor (though if that was ****** up it would throw a battery light, but maybe if it isnt hooked up and you have a gaping hole in your pipe that might do it) and mass air flow sensor. make sure you MAF isnt on backwards or whatever.
 
i've checked and rechecked the air temp senor. Did you have any problems with any of the little tubes getting kinked going to the blow off line?
 
i tried it and it worked the first time. but after i turn the car off and on a couple of times it comes back on. any more suggestions?
