Map sensor has the biggest affect on fuel metering. When it goes out of range you will have a pretty severe running problem. The throttle position sensor is more forgiving. You might not even notice the little hiccups that the Engine Computer is detecting. Both of these sensors don't fail real often. They have a 5.0 volt feed circuit in common and the ground return circuit in common so you might consider a wiring problem, not a sensor problem. The Chrysler scanner will tell how many engine starts since the codes were set. If both set at the same time, suspect something related to both of them.
