Frequently asked questions about U061C

What does U061C mean?

Lost Communication With Reductant Temperature Sensor A. The control module stopped receiving expected network messages from the Reductant Temperature Sensor A node on the vehicle communication bus.

Is U061C generic or manufacturer-specific?

U061C is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U061C 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 U061C is removable in your case.
