Those codes are all throttle position sensor related. Could be as simple as a loose wire. Would also explain the issues after going through the carwash if an exposed clip got damp.
I would start checking the wires and connections before looking for other issues.


Edit: Too slow. So they checked the sensor itself did they check the wires leading to it? If it ran fine after they checked it then went again it could be a loose wire.
