Frequently asked questions about U061D

What does U061D mean?

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

Is U061D generic or manufacturer-specific?

U061D is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U061D 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 U061D is removable in your case.
