p0073= ambient temp. sensor high input
p0107= map senor circuit voltage low
could be dirty on the sensor, or the sensor could be going bad, u can clean it, and plug it back in and see what happens, is the truck running rough, idling low?
and the ambient temp sensor pics up the temp outside i believe, and correct me if im wrong, its located on the left side front, either by the headlight, or back in behind the bumper down on the bottom in the center, sometimes their faulty, check your overhead, and see if your getting a temp, or if it says something else... you can also try cleaning it, and plugging it back in to see what happens... just my .02 worth... glad if i helped...
i had a map sensor too high code a couple of days ago. i removed the quad fooler and i have been fine since. I figured i might have had too much fooling with the smarty and all, it only started when i put the smarty on, and i think the smarty boost fools also.
Ide try to clean up the map sensor and try again. as far as the p0073, clean it too and clear the codes, if it comes back on you might need a new sensor.
Well I forgot to mention that after installing the bhaf the cheack engine loght came on and then I checked the codes and they came up. now the motor light is off havent checked the codes again. could it be I forgot to plug in the sensor on the torque tube?? the truck is not running rough at all.
