Frequently asked questions about U0685
What does U0685 mean?
Lost Communication With Catalyst Temperature Bank 1 Sensor 2. The control module stopped receiving expected network messages from the Catalyst Temperature Bank 1 Sensor 2 node on the vehicle communication bus.
Is U0685 generic or manufacturer-specific?
U0685 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove U0685 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 U0685 is removable in your case.
