I have a 2002 Dodge Ram 4.7L V8
I did the on off on off on trick with the key in the ignition and got two
codes for my check engine light
The first one is in my Haynes Manual -
EVAP system leak monitor, medium (0.40) leak detected
Question #1 - what does that mean? I was told it is something with my fuel
vapor recovery system and that it may be under a 7/70 warranty on my
emissions of my dodge. Anyone know?
Question #2 - the P1491 code is not in my manual. Anyone know what that
code is? I was told it might be a cooling fan fuse.
Thanks for any help
