HN16 CHECK TURBOCHARGER PRESSURE WASTEGATE ACTUATOR OPERATION
NOTICE: Do not exceed 103.4 kPa (15 psi) of pressure applied to the turbocharger actuators, excessive pressure will damage the actuators.
• Disconnect the turbocharger wastegate control hose from the turbocharger wastegate actuator.
• Record each of the turbocharger wastegate actuator linkage positions.
• Using a suitable hand pump with pressure gauge, pressurize the turbocharger wastegate actuator to 82.7 kPa (12 psi).
Does each turbocharger wastegate actuator linkage move from the starting position and does the pressure remain steady?
Yes | No |

HN17 CHECK PRESSURE SYSTEM TO THE TURBOCHARGER WASTEGATE ACTUATOR
NOTICE: Do not exceed 103.4 kPa (15 psi) of pressure applied to the turbocharger actuators, excessive pressure will damage the actuators.
• Disconnect the pressure supply hose from the inlet of the turbocharger wastegate regulating valve solenoid.
• Disconnect the pressure control hose from the outlet of the turbocharger wastegate regulating valve solenoid.
• Using a suitable adaptor, connect the pressure supply hose to the pressure control hose.
• Disconnect the turbocharger wastegate pressure supply hose from the high pressure tube.
• Using a suitable hand pump with pressure gauge, pressurize the turbocharger wastegate pressure supply hose to 48.3 kPa (7 psi).
Does each turbocharger wastegate actuator linkage move from the starting position and does the pressure remain steady?
Yes | No |
|---|---|
INSTALL a new Turbocharger Wastegate Regulating Valve solenoid. | A pressure system leak or restriction is the cause of the concern. DIAGNOSE the turbocharger wastegate pressure system leak |
