Warning

•  A hot engine can cause severe burns. Turn off the engine and wait until it is cool before servicing.

OCV for No.1 Cylinder Deactivation

Coil resistance inspection

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Disconnect the OCV for No.1 cylinder deactivation connector. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

3.  Measure the resistance between terminals A and B using an ohmmeter.

•  If not as specified, replace the OCV for No.1 cylinder deactivation. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

4.  Install in the reverse order of removal.

Operation inspection

Caution

•  Do not apply voltage of 16 V or more to the oil control valve for No. 1 cylinder deactivation because the oil control valve for No. 1 cylinder deactivation will be damaged.

1.  Remove the OCV for No.1 cylinder deactivation. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

2.   Verify that the battery voltage is between 12 and 16 V. (See BATTERY INSPECTION.)

3.  Connect the battery to the OCV for No.1 cylinder deactivation connector (2 terminals) as shown in the figure.

4.  Verify that there is an operation sound from the OCV for No.1 cylinder deactivation when applying battery voltage between OCV for No.1 cylinder deactivation connector terminals A and B.

Note

•   A click sound is heard when the OCV for No.1 cylinder deactivation operates normally.

•   If the operation sound cannot be heard, replace the OCV for No.1 cylinder deactivation. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

5.  Install the OCV for No.1 cylinder deactivation. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

OCV for No.4 Cylinder Deactivation

Coil resistance inspection

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Disconnect the OCV for No.4 cylinder deactivation connector. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

3.  Measure the resistance between terminals A and B using an ohmmeter.

•  If not as specified, replace the OCV for No.4 cylinder deactivation. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

4.  Install in the reverse order of removal.

Operation inspection

Caution

•  Do not apply voltage of 16 V or more to the oil control valve for No. 4 cylinder deactivation because the oil control valve for No. 4 cylinder deactivation will be damaged.

1.  Remove the OCV for No.4 cylinder deactivation. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

2.   Verify that the battery voltage is between 12 and 16 V. (See BATTERY INSPECTION.)

3.  Connect the battery to the OCV for No.4 cylinder deactivation connector (2 terminals) as shown in the figure.

4.  Verify that there is an operation sound from the OCV for No.4 cylinder deactivation when applying battery voltage between OCV for No.4 cylinder deactivation connector terminals A and B.

Note

•   A click sound is heard when the OCV for No.4 cylinder deactivation operates normally.

•   If the operation sound cannot be heard, replace the OCV for No.4 cylinder deactivation. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

5.  Install the OCV for No.4 cylinder deactivation. (See OIL CONTROL VALVE (OCV) FOR CYLINDER DEACTIVATION REMOVAL/INSTALLATION [WITH CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
