Coil Resistance Inspection

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

2.  Remove the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

3.  Remove the battery. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

4.  Remove the air inlet pipe and turbocharger air inlet hose as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

5.  Disconnect the OCV connector.

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

•  If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

7.  Install in the reverse order of removal.

Spool Valve Operation Inspection

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

2.  Remove the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

3.  Remove the battery. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

4.  Remove the air inlet pipe and turbocharger air inlet hose as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

5.  Remove the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

6.  Visually inspect from the oil passage and verify that the spool valve inside the OCV is at the position shown in the figure.

•  If there is any malfunction, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

7.  Verify that the battery is fully charged. (See BATTERY INSPECTION [SKYACTIV-D 2.2].)

•  If not as specified, recharge the battery. (See BATTERY RECHARGING [SKYACTIV-D 2.2].)

Note

•  When applying battery positive voltage between the OCV terminals, the connection can be either of the following:

―  Positive battery cable to terminal A, negative battery cable to terminal B

―  Positive battery cable to terminal B, negative battery cable to terminal A

•  If there is any malfunction, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

9.  Stop applying battery positive voltage and verify that the spool valve returns to its original position.

•  If there is any malfunction, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

10.  Install the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

11.  Install in the reverse order of removal.
