Komatsu FG 18-16:
Staying in limp mode with codes

Lift has code 1218 and code for open circuit on ECM temp sensor. Already repaired the temp sensor wiring and tried 3 OEM sensors. Replaced the ECM. Code's will not clear. Live stream always shows 104f but builds temp while running. Cut the machine off and restart. It shows 104f again and will start building temp again. Freeze frame data always shows temp at -40f. Any ideas? Thanks Trai
