This morning 14 deg (F) after about 1/2 hour of driving the engine coughed and the check engine light came on. I ran another 1/2 hour and shut if off for 2 hours, now the check light is off. I checked the codes and there are two.
P0251 - Inj Pump Fuel Metering Ctrl A Error
P0514 - Battery Temp Sensor Ctrl Rang/Perf

Should I be worried? What do they mean?

 

Are these codes from the Quad Race Box?
Should I take it to the dealer?

 

i get p0514 code in winter from plugging block heater in. posted in here couple mths ago. from what i understand its not a big deal. that code went away after a few starts not being plugged in. other code, i dunno

 

The 251 code is typically the FCA valve.

 

The dealer re-flashed and siad that he was suprised that it had never thrown a code before with 69K on it. Said the boost and rail pressure was fine, and that it was prop due to the temperature.

They did say that the valve body in the transmission has a small leak and they want me to bring it back next week. The tech was gone, they said it would cost the $100 deductable. How can you tell if the valve body is leaking? Don't you need to remove the pan?
