I used to get this in the winter using the block heater, apparently the sensor activates the DTC because the fuel can gel on a diesel if its not cold enough. I was told to only use the heater is less than 20.

Thats probably my problem then. Weird thing is it doesnt cut my power until i drive home from work. So i will stop plugging it in and put my intake heater back in.

Incidentally, I have the full set of Helm service manuals for '05 which may be similar if I can look something up for you
