Turbocharger Pressure Check

Disconnect pressure hose (Black hose) at lower fitting on turbocharger wastegate solenoid. Plug hose fitting on turbocharger wastegate solenoid. See Fig 1 . Turbocharger wastegate solenoid is located at passenger's side of engine compartment, just below air cleaner and contains a 2-pin Black electrical connector with Red and Red/Yellow wires in electrical connector.

Connect pressure gauge to disconnected pressure hose. Drive vehicle at full throttle in 2nd gear with engine RPM at more than 3500 RPM. Note turbocharger pressure once pressure stabilizes on pressure gauge. Turbocharger pressure should be 6.4-14.7 psi (.45-1.0 kg/cm² ).
If turbocharger pressure exceeds specification, check for a defective turbocharger wastegate actuator, turbocharger wastegate valve or turbocharger wastegate actuator hose. If turbocharger pressure is less than specified, check for a defective turbocharger wastegate actuator, pressure leaks or a defective turbocharger. Repair or replace components as necessary. Remove pressure gauge and reconnect pressure hose.
