So I recently picked up a 2007 ranger. 2.3 5 speed. I’ve been going over the truck. And I’ve discovered I’m getting a P1633 code “keep power alive voltage too low”. The pcm is seeing 14v at idle. I don’t have any blown fuses. All grounds are cleaned. Battery terminals and cables are replaced. Only thing I’ve noticed is the alternator doesn’t start to charge, unless you bring the rpm’s up a little. Then the regulator kicks in. I also notice the truck feels down on power.
thoughts on where I should be looking next?
