U061FLost Communication With Exhaust Gas Temperature Sensor Bank 1 Sensor 1

U061F is a network communication code indicating that a control module has lost contact with the exhaust gas temperature sensor for bank 1 sensor 1, which is the sensor closest to the engine on the bank containing cylinder one. The computer detected that the expected serial data message from that sensor or its interface module is missing, so it cannot monitor exhaust temperature for that bank.
