Fuel temperature
 

I have another question. Other then tge p0093 code i was wondering why the code doesn't come up until the fuel temp reaches around 100°. It does seem to .aintain the same temperature as the coolant temp. Should it be lower? Does anyone know if there is a temp the fuel should run at. One more thing. My ambient outside temperature sensor does not work & and the display on the rear view mirror says OC.
Thank you
Have a great day.
