2002 Dodge Ram--P1491 fault code
Can anyone help me figure out what this code is and how to fix it wihtout paying big bucks? We took the truck to autozone and they scanned for the code. P1491 is what they came up with but said it was an OEM code and couldn't tell us anything else. All help is appreciated.

Re: 2002 Dodge Ram--P1491 fault code
Thanks for the replys. We had the Dodge dealer hook it up. It was the a/c fan and a fuse.

Re: 2002 Dodge Ram--P1491 fault code
it's in the pdc {fuse box} under the hood it's a 25 amp fuse at the centre row at the very end towards the engine

Re: 2002 Dodge Ram--P1491 fault code
OK, I replaced the fuse and disconnected the battery but I still have the check engine light on and the P1491 code, any suggestions. THe truck has almost 90K on it. If there is a tSB on this, wouldn't this be covered since it is a design flaw, and probably should have been a recall.
