P0642 points to ecm/pcm and/or 5v fault. P2122 points to throttle position sensor/throttle body and/or accelerator position fault. P1618 points to 5v sensor voltage varying too much, from the ecm/pcm. Most sensors in EFI systems use 5v. This may be difficult to diagnose and requires an expert in EFI systems familiar with advanced electronics. 5v is distributed everywhere and any one part or wiring may be shorting 5v creating false error codes for average mechanics to chase a problem with parts replacement instead of troubleshooting using advanced techniques like measuring for 5v or lack of.
