U05A0 Code - Invalid Data Received From Evaporative Emission System Leak Detection Control Module
Quick Answer
The Diagnostic Trouble Code (DTC) will set when a network concerns occur during module-to-module communication. Common causes include Faulty Evaporative Emission System Leak Detection Control Module, Evaporative Emission System Leak Detection Control Module harness is open or shorted, Evaporative Emission System Leak Detection Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U05A0 Description
- Invalid data network concerns are set when data is transferred within the normal inter-module message but contains known invalid data. The transmitting module logs a DTC related to the invalid data concern.
- Missing message network concerns are set when missing message concerns are logged by the module upon failure to receive a message from another module within a defined retry period.
What are the Possible Causes of the DTC U05A0?
- Faulty Evaporative Emission System Leak Detection Control Module
- Evaporative Emission System Leak Detection Control Module harness is open or shorted
- Evaporative Emission System Leak Detection Control Module circuit poor electrical connection
