P1173 (Rotor Calibration Fault) code


AlfaDiag's detected a P1173 fault on my 1.8TS. Reading through previous posts, this could be the MAF or lambda sensor.

Does anyone have any more info on the code?

I changed the MAF recently, albeit for a used one, and the car's running pretty well. Not 100% though. Maybe a brand new MAF would be an idea.

I've just cleaned the old one, so I'll see how it runs with that...
