TURBOCHARGER SOLENOID VALVE INSPECTION [SKYACTIV-D 1.5]

id0113q2991900


Resistance inspection

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].)

2.  Remove the turbocharger solenoid valve. (See TURBOCHARGER SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

3.  Measure resistance between turbocharger solenoid valve terminals A and B.

Turbocharger solenoid valve resistance (specification)
9.8—11.2 ohms [20 °C {68 °F}]
•  If not within the specification, replace the turbocharger solenoid valve. (See TURBOCHARGER SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)


Airflow Inspection

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 1.5].)

2.  Remove the turbocharger solenoid valve. (See TURBOCHARGER SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)

3.  Inspect airflow between the ports under the following conditions.

Caution
•  If Mityvac is used to apply positive pressure to the port, the pressure may increase excessively and correct determination may not be possible. Inspect the airflow by directly blowing air with your mouth using a rubber hose inserted into the port.
•  When verifying the airflow by blowing air with your mouth into the port, be careful not to accidentally breathe in air.

Measured condition*1

Continuity between ports
While covering port A, apply pressure to port B
No airflow between ports B and C*2

*1  :Whether or not there is continuity between terminals A and B, the airflow condition listed in the table is always normal.
*2  :When the pressure of the air being blown from your mouth is too high, slight airflow may be detected.
•  If not as specified, replace the turbocharger solenoid valve. (See TURBOCHARGER SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)


PID/DATA Monitor Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Start the engine.

3.  Access the PID/DATA monitor item VGTURB_ACT and simulation item VGTURB_DSD using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].)

4.  Verify that the value of the conforming PID VGTURB_ACT increases when the simulation item VGTURB_DSD value is increased.

•  If not as verified, replace the turbocharger solenoid valve. (See TURBOCHARGER SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
