Frequently asked questions about U067E

What does U067E mean?

Lost Communication With Exhaust Pressure Control Valve B Sensor/Switch. The control module stopped receiving expected network messages from the Exhaust Pressure Control Valve B Sensor/Switch node on the vehicle communication bus.

Is U067E generic or manufacturer-specific?

U067E is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U067E 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 U067E is removable in your case.
