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?

If your engine light is on and you’re seeing the u011a fault code, it could be due to a faulty Exhaust Gas Sensor Module, an open or shorted harness, or poor electrical connection. To fix the issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the u011a fault code?

If you’re experiencing the u011a fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few things you can do to fix it. The cause of this issue could be a faulty exhaust gas sensor module, an open or shorted harness, or a poor electrical connection in the module circuit. To address this problem, you should visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

What are the consequences of ignoring the u011a fault code?
