Fault codes

[A.stewart]

EML came on a year ago and thrown up several faults - my mechanic wasn’t 100% sure what was wrong as there was too many sensor faults and he said it was unusual for them to all go together. I’ve drove the car for a year and had no issues apart from the EML on. Today the car performance felt poor with speeds above 60mph. I don’t have up to date codes but the below codes show what flagged up last year.

I would get another scan as those codes may have been caused by sensors being disconnected during some work on the engine.
A fresh scan will at least show current faults since the historic ones were cleared....at least you'll know the current fault
