i have 2 codes on my 2006 ford e450 with 6.0 engine . 0701 and 0301 what can this be ?

Question

This truk is very slow . Im only getting 40 km/h and the revs wont go more than 2200 rpm.

Answer 1

P0701 is not used by this car, in the service manual. Try to use a different OBD-II reader that is compatible with your car you might get different code

P0700 is most likely related to the transmission, you may have to take it to a transmission specialist

 

P0301 is a cylinder 1 misfire, could be from a bad spark plug, ignition coil, fuel injector and so on
