• 10154683Feb 18, 2019Fuel system. In a gasoline direct injection (GDI) engine, highly pressurized gasoline is injected via a common rail fuel line and injectors that deliver fuel directly into the combustion chamber of each cylinder. In comparison, in a conventional multi-point fuel injection (MPI) engine, relatively low pressure gasoline is injected into the intake port of each cylinder. Due to high fuel pressures in a GDI system, servicing the…
• 10154682Feb 15, 2019Engine. Applicable vehicles with 2.0L Turbo and 2.4L engines may experience the Check Engine warning lamp illuminated with DTC P1326.
