Here's a MANDATORY / NECESSARY fix for your P0122 and/or P1122 and P0342 DTC on Korean made cars. After replacing the TPS Throttle Position Sensor, you have to pull the TCM fuse with car key in ignition off position for 5 minutes, then replace TCM fuse, clear ECM codes, take a drive, leave in D gear only for 250 - 500 miles. Do not use the hold or do any sport shifting for 250-500 miles. Best to pull ECM fuse(s) too at same time for 5 minutes, as ECM and TCM work together.
