REGULATING SOLENOID VALVE INSPECTION [SKYACTIV-D 2.2]

id0113z7265700


Resistance inspection

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

2.  Remove the regulating solenoid valve. (See REGULATING SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

3.  Measure the resistance between the regulating solenoid valve terminals A and B.

Regulating solenoid valve resistance (specification)
9.8—11.2 ohms [20 °C {68 °F}]
•  If not within the specification, replace the regulating solenoid valve. (See REGULATING SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)


Airflow Inspection

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

2.  Remove the regulating solenoid valve. (See REGULATING SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

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 regulating solenoid valve. (See REGULATING SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)


PID/DATA Monitor Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Start the engine.

3.  Access the PID/DATA monitor item REGV and simulation item REGV using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].)

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

•  If not as verified, replace the regulating solenoid valve. (See REGULATING SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
