I have a 2010 RAM 2500 with 6.7L Cummins.

I don't know if this is just a coincidence, but the fuel filter has recently been changed, and it just seems unusual that this code popped up as soon as I programmed it.

Anyhow, plan to change the filter, do not know what else I can do; draining fluid in the filter did not help.

The light comes and goes and is on more often than it is off, though.

Any thoughts or suggestions?

Thanks
