hello, your first code p2074 is set most likely cause of code p0122, po122 is on because there is a problem with your throttle postition sensor. its most likely going to need a new throttle position sensor installed. to accurately diagnose this will requre use of a scan tool to monitor voltages that the pcm is seeing from the sensor.
