Re: 2002 Dodge Ram--P1491 fault code

I found that P1491 related to a blown fuse (25A) for the A/C condenser fan. A/C fan would not engage when engine was warm and A/C on. My mechanic also noticed that my fan clutch was going out as it was turning really slow, it really should be roaring. It could be that the A/C condenser fan was having to work overtime to compensate for the engine fan, hence blowing the fuse. Both fans work great now, all in all, $160 for parts and labor.
