Well I'm at a complete loss. About a year ago all my sensors "pegged" on my 2000 Dakota. I pulled over and shut off the engine. When I restarted everything was OK, but my check engine light was on. I got the code, P1491 which pointed me to the electric cooling fan. I checked the fuse, OK, checked the relay and it was fried. Replaced the relay, but the light stayed on. I didn't worry about it since it was winter. Made it thru the summer OK so never gave it a second thought. I'm in St. Louis so I have to get emmisions inspection and I failed becasue of the code. If I jumper across the common and N.O contact, the fan runs fine. While running, I have 12 V on one side of the relay coil. I check continuity from the other side of the relay coil to the PCM plug and it's OK. That's all ther is to it, I think. I've reset the code, but it's back as soon as I start the truck. I've read about an AC condenser fan fuse, but don't think I have one on my 2000. Can anyone help me out?
Thanks,
