Frequently asked questions about U05A0

What does U05A0 mean?

Invalid Data Received from Evaporative Emission System Leak Detection Control Module. The control module detected a condition consistent with a leak affecting the Invalid Data Received from Evaporative Emission System.

Is U05A0 generic or manufacturer-specific?

U05A0 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U05A0 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 U05A0 is removable in your case.
