Just for info.
Our Kodiak motorhome threw a CEL while it was running hot (240-250°) up a long steep hill. 4,700 mi. Air temp was about 110° F.
First code was P0495 Cooling Fan Speed. Engine data seemed normal.
Second code was P2563 Turbo Boost Control. 3 times it failed. Third time:
Fuel Temp 221° F???
EGT 899°
Desired vane pos 21%
Actual vane pos 45%
RPM 2114
Coolant 224°F
mm3 fuel 101.
Note: Kodiaks have Electronic Engine Exhaust Braking from the factory with a dash mounted switch to turn it on and off. I had it on. They also have manual DPF Regen via another switch on the dash. Regen was not active at the time.
Odd. 221 deg fuel temp?
Perhaps the fuel is being heated by the radiator water? Guess I have to learn about Kodiaks.
