After disconnecting and connecting G62 sensor I can't erase 16502 fault code, also cooling fans are working all the time. Maybe I damaged ect sensor while disconnecting it... Engine coolant temperature on dash panel don't rise above 50, and in mvb ecu temperature rises to about 60. I don't understand why cooling fans are working, is it limp mode when ect sensor don't have signal? What to do?

You sure it's plugged back in correctly?

Unplug again, inspect wiring in the area where you unplugged it, inspect connector pins, measure resistance of sensor and compare to spec.

It's plugged back correctly. Resistance is very difficult to measure because there's very little space.
