This is my very first post so please bear with me.
I have this issue with my 2017 Hyundai Santa Fe XL V6 (204000 KMs) where if I idle for about 10-20 minutes the car’s RPM will rise for a very short moment and come back to normal. However, if I try to drive away after that the car goes in LIMP mode. The error codes that I get are P2106, P2110, P0638. It doesn’t happens when I keep driving. I could drive for literally hours without issues, however, the whenever I idle for more than 10 minutes this will happen.
These error codes do go away on their own without me clearing them after some time. But the next time I idle they’re back. I am not sure where to start so please help.
