Re: fault codes
Hi and welcome.
P0054 can indicate that the downstream oxygen sensor electrical harness or the sensor is faulty, but I may be able to be more specific if you pop the VIN up.
Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.
