- Interface with engine management system to retrieve fault codes and perform tests. Had codes P0491 and P0492 secondary air injection system fault. Looking into diagnostics there is a technical service bullion about possible secondary air injection system air ports being blocked and may be covered under warranty. There seemed to be excessive crank case pressure. There is also a P052E PCV valve malfunction that may be related to plugged air intake ports.
