New to working on these cars. What are the functions of the power module? Do they measure airflow? I know the turbo intake hose goes through the module.
What is the function of the power module?

Turbo dodge does not have MAF (Mass Air Flow) sensor. They have MAP (Manifold Absoute Pressure) sensor.

Click on power module and look at the wiring diagram and you'd know what it controls.

pm supplies and switches power for different things in the car like ignation , fuel pump etc
it switches power on to things through the asd - automatic shutdown relay
it also contains your voltage regulater for the chargeing system
there are a couple common things that affect it
if the pick up or wireing for the pick up in the distribuator is bad - the asd will not send power from the module to the ign or fuel pump
if the voltage reg goes bad you don't need to replace the module - just disconect the field wires going to the pm from the alternator and add in an old style voltage reg that bolts to the firewall or inner fender
usually a much cheeper fix than replaceing the module
