HELP,
I previously had a P1131 code and now have a P0113 without changing anything. This appeared the same time the alternator light came on and stayed on. There is no appreciable rise in voltage when checking at the battery with the engine off and on. I'm assuming that I need a new alternator (car only has 55,000 miles). What does that code mean and can these 2 things be related? Any unwritten tricks to replacing the alt. Looks a bit tricky.
Thanks to anyone who can help.
