well last night i did some final touches on my CAI and forgot to put back in the MAF sensor and went to start it. it started weird, and i let it sit for about 3 secs when i noticed i left the sensor unplugged. well got back in the car and the SES light was on. now im freaked! when i first installed my Injen CAI it came on but eventually went off later that night. this isnt going off.

any ideas what it could be?

could the sensor be fried?

could it be something big?

now if the sensor were fried the car instelf wouldnt run or would start up akward right?

well she starts up fine, idles fine, and runs fine.

now when i installed the sensor back into the tube i did have the battery completely connected but in order for it to be fried it must first blow a fuse right?

i have a 2003, touring model so if there has been any recalls on this sensor please let me know. i want to be heavily knowledable when i go into the dealer tomarrow if something needs to be done.

thanks for your help everyone,

You just need to reset your ecu. Go here for instructions . Or just go to the dealer and have them reset it. Everything should be fine after that.

John,

Everything is fine. You didn't fry the sensor. Leaving it unplugged only trips the CEL because the engine does not know how much air is passing through the intake tube into the plenum and the ECU doesn't know how to compensate.

It will eventually go off or you can reset it but you didn't do any damage to the car. You can't drive it around like that, but idling for a few seconds won't hurt anything.

thanks everyone for your help. i managed to reset the ECU. on my way to entering my first practice into erasing it i managed to do it my first time. now knowing how confusing it is to reset it i dont think im going to be doing that again.

thanks everyone.
