04 2500 code issue help please
 

tonight my 04 displayed this code (P0073) help please?

Chilton says P0073 Ambient temperature sensor circuit, high voltage
P0072 Ambient temperature sensor circuit, low voltage
Chilton and Google= both great tools

could be....
Intake charge temp sensor:
it is a map sensor reads temp and pressure

If you get code P0107, then its almost def the sensor

hope this helps
