SES light on and code p102

**LS1 Trans am** · 02-25-2007, 06:04 PM

What would be wrong with my car possibly if I'm thowing the p102 or something like that code, It said something like Mass Air Flow: Low Voltage or something like that. What would cause that? I was thinking it could be my alternator, because when I start my car my tach and speedo go all the way up and down real slow and also it resets my trip, Any ideas?

P0102? See www.gearchatter.com/viewtopic8916.php

The gauge sweep/trip resetting to zero is from low battery voltage on the '99 cars. Here's the TSB on it: http://home.earthlink.net/~cetera/pics/aug99tsb.jpg

2001NBMZ28 has your information in his link. It is as stated in the Service Manual. I noticed you ported your Maf. Make sure you didn't damage the hot wires. They keep a fixed temperature above ambient temperature.

It was working and then I just had the voltage regulator replaced on the alternator, that's why I think it's the alternator messing with my voltage. It wasn't throwing this code until after the alternator was fixed. I'm about to go to o'reilys and get a new one with a lifetime warranty for $108 before it messes up something.

Ran the tests off that website provided (although all I have is a test light and a ohm meter) and I had 5 volts between the signal and a ground and had the test light go off when I tested the ignition+ to the ground and then I found the engine sensor fuse was blown. So I replaced the fuse and went for a ride and the service engine light never went off, then when I got back I found the fuse was blown again. Any ideas?

Again....did you check your wires in the MAF for damage or trash?

**LS1 Trans am** · 02-27-2007, 05:29 PM

Talking about taking the maf apart or the 3 wires that are in the opening? Those wires arn't broken. Anything else? What about my alternator, it never hummed when I just turn my key on.. Maybe it's doing something crazy? Like to much voltage or not enough.

I would maybe consider making this right with him. Think about how you would feel if someone sold you a part without telling you there was something wrong with it. Just ain't right.
