I noticed that my volt gauge hovers around 12.5V - 13V while I'm driving.

Also, I would get the PSM/ABS lights once in a while ... Durametric says Hot Film MAF ... although I just replaced the MAF about 3 weeks ago.

Is this the sign of the alternator going out the door or voltage regulator?

Also ... would a bad alternator kill a MAF in the long run?

I'd just like to know what everyone's experience before I replace the alternator ...

Thanks in Advance ...

 

The first symptom in my car of a bad alternator was a dead battery. Do alternators die a slow death?

 

Mine is about the same. Starts out about 13.5 just after starting and then drops to around 12.5 after driving for a while. I thought maybe it was load based charging like a lot of newer cars have.
