One sensor that will cause a problem is the MLPS. Another missing sensor is the transmission fluid temperature sensor (TFT.) The auto PCM is looking for those sensors and will set codes if they are missing.
Another problem is that the auto PCM is looking for two shift solenoids, one lockup solenoid, an electronic pressure control solenoid, and a coast clutch solenoid. Each one of those will set a code if they are missing.
