If the EML is not showing there is probably nothing to worry about. Did Carly list the DTC as "serious" or "non serious". I don't recognise the code but you could try this (a lambda failure would lead to emission codes, EML and performance issues)...

Turn ignition ON, start the vehicle and let it idle for at least 30 seconds.
Then drive the vehicle for at least five minutes at more than 25mph.
Finally let the vehicle idle for at least 30 seconds before shutting it OFF. The whole drive cycle must take at least 10 minutes and without turning off or on the ignition during the test.
This Drive Pattern should allow the computer to clear any permanent code, if the problem is fixed and not recurring.

Certain DTC codes are specified as permanent and can not be cleared by your scanning tools. They need a specified running cycle (above) to demonstrate to the ECU that the problem has disappeared.

Google 'Permanent DTCs' or 'PDTC'.

I obviously don't know but if it was my car and was driving OK, no warnings, I would be happy. I have ignored codes in the past. Sometimes it can be a spurious signal, or budget code reader, or just a bad connection in the OBD terminal.
