Default ECM 5A fault. Three way catalytic converter

Hi, just had the EML appear, red the codes on Vida, and the significant one was

ECM 5A Three way catalytic converter TWC efficiency - faulty signal

Has anyone had any experience of this? I have a few long trips in the next few days so keen to sort it ASAP. Thank you for your help.
