The U011A code is a Controller Area Network (CAN) fault code. CAN is a vehicle bus standard designed to interconnect automotive devices without a host computer.

CAN bus uses two dedicated wires for communication, CAN high and CAN low.

The U011A code sets when a periodic message from the Exhaust Gas Sensor Module has not been received. The Diagnostic Trouble Code (DTC) indicates that there is a lost communication with the Exhaust Gas Sensor Module. The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise.

What are the possible causes of the u011a automobile fault code?
