On your 2012 Hyundai Genesis Coupe 3.8, those codes point to issues with the throttle and accelerator pedal systems. P0122 and P0222 both indicate low voltage signals from the throttle position sensor circuits, while P2106 and P2110 are “limp mode” codes triggered when the ECU detects a problem with throttle control and limits engine power to protect the car. Together, these suggest a problem with either the throttle body assembly (dirty, sticking, or failing sensor), the accelerator pedal position sensor, or wiring/connectors between them. A good first step is to inspect and clean the throttle body, check for damaged wiring or loose connectors, and clear the codes. If the problem returns, testing the throttle body and pedal sensor voltages with a multimeter will help pinpoint which component needs replacement.
