Re: 2002 Dodge Ram--P1491 fault code

Just wanted to let everyone know that this error must be very common because I’ve seen it twice now. Once at 75k miles and recently again at 96k. Both times I forgot to remove the battery cable after replacing the fuse and both times the check engine light failed to extinguish. Once I removed the battery cable and reconnected, the check engine light went out. Hope I can remember to do that next year, because I’m sure the fuse will blow again.
