I have a 1999.5 F250 7.3 diesel and on my Y pipe there is no hole for air intake heater but I am throwing a code P0541 for intake heater a circuit low . I've read online people remove them and put something on there to trick the computer but if my truck never had one why am I throwing this code

 

if it isnt a hard code and setting a CEL i wouldnt worry about it

 

Check the air box. Thats where mine is.
