I have the check engine light on and code p1491(Malfunction control
auxillary emission control). I have found online where it is the Egr
valve that could be bad. I also found online where it can be the
radiator fan. I am going to change the radiator fan on the driver side
because it is dead and am hoping this fixes. Anyone experience this
code and a repair? Thanks:)
