Frequently asked questions about U069C
What does U069C mean?
Lost Communication With Exhaust Gas Temperature Sensor Bank 2 Sensor 3. The control module stopped receiving expected network messages from the Exhaust Gas Temperature Sensor Bank 2 Sensor 3 node on the vehicle communication bus.
Is U069C generic or manufacturer-specific?
U069C is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove U069C at file level?
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U069C is removable in your case.
