I have a 2009 Polaris assault rmk 800 and it was flashing 5 times and putting it in limp mode indicating a egt sensor so I replaced it and ran it for 5 minutes over 4000 rpm and it wasn’t going away so I brought it into the dealer and they cleared all the codes and I brought it home and it was still putting it into the limp mode and flashing 5 times after a new egt sensor, any idea what it might be?
