today I did the oil change andchanged the air filter on my 02' Z, and forgot to plug the mass air flow sensor back onto the car. I had turned the car on for a sec. and noticed CEL was on. I replug the mass air flow sensor back into the intake, and check engine light is still on??
Have I done something bad to it??
I don't get it at all. Anyone knows?
Thanks

Check that you reconnected everything well and then leave if overnight.Sometimes the codes clear themselves after a while. If its still on read the code and find out what the problem is.

disconect the batt for 5 min,s

yeah i pull the code and it shows four code that are "H". From my understanding if it's an "H" then I shouldn't worry about it? But if it's "C", then I should take care of it? Anyways i just went ahead and reset those "H" code, and check engine light went away.
