Here's a thought though. I've disconnected my battery for as much as 5 minutes when I've gotten a CEL in the past. Sometimes it would stay off, but mostly it came back. Someone told me to actually disconnect the ECU caps so there is no residual power to the ECU. Every time I've done that, the CEL never comes back. I read somewhere that the ECU has some kind of wire that can get power even if the battery is disconnected...this sounds ludicrous, but...just to be safe, I did it.
Just my $.02
Bye bye 2g, hello 1g! Can I change my name to 91TSiORL??

I was just kidding I was thinking disconnecting the battery and not the ecu itself which I have read takes 10 minutes plus. If I understood the original post he was talking about dissconnecting the battery and not the ecu itself.
If resetting the ecu is all you want to do then you do not need to disconnect the batt at all. Go to TMO.com and look up how to reset the ecu. All you have to do is pull a fuse in the fuse box by your left foot for like 15 or 30 seconds (on 1G's...not sure if 2G's are the same or not). Has worked for me every time (now I have the pocketlogger to do it). It's the fuse on the lower right corner (I believe it also controls the lights that come on when you open the door).
well ive been recently getting the CEL for my air temp sensor in the MAS. I replaced it with a used one but i am still getting the CEL. I left it off for an hour (forgot about it. ) and it is still on. well ill have to try that ECU reset. I hope it works. Has any of u had this problem?

My 2G MAS throws code 13 (intake air temp sensor) all the time too. I am on my 3rd 2G MAS b/c I thought is was a bad MAS. But after 3 MAS's I do not think that that is the problem. I am in the process right now of making a custom CAI (cold air intake) for the filter. I'm thinking that the extremely hot air that is getting to my filter may be the problem (intake temps on my pocketlogger have at times gotten up to 115 deg. or more!).
Yeah, if you have'nt had a CEL in 6 years then you may have a burned out bulb. J/K. You may not, but I throw them all the time (mostly the MAS code and the EGR code). Oh well, I just cancel them out w/ the pocketlogger. They don't seem to cause any problems except the light.
