10 months ago. Millie (my Volvo) got a new battery plugs and wires. Recently she shut off while driving. Had her towed to a garage. They said it was the alternator. Had a new one put in. A week later all of a sudden she didn't have any more power. I was told she likely needed the PCV replaced a gasket and an O2 sensor. However, when I look up all of the codes, the most common theme I see is circuit problems fuses and defective wiring. I can't afford to get ripped off and just keep throwing money I don't have at a problem no one seems to put the big picture together & there isn't a Volvo dealership in the area I live in.

Because most of these errors are electrical, i would confirm your battery is getting charged by your alternator. They could be false errors due to lack of voltage. A charged battery should show over 12 volts, and a alternator will bring that up to around 14.0 volts. Hopefully you have a voltmeter to check this. If not, you can get them fairly cheap and its always good to have one around the house.

 

Erase the codes, drive the car and recheck codes.


What codes come back? If any address the ones that come back first.

Did your new alternator come with a new overrun pulley? Or was the old pulley reused?
(and what "wires" were replaced?)

 

Hi

Did you end up getting to the bottom of this issue?
