SKYACTIV-G 1.3, SKYACTIV-G 1.5 (With 4-1 Exhaust System)


Coil Resistance Inspection

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2.  Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

3.  Disconnect the OCV connector. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

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

OCV coil resistance
6.9—7.5 ohms [20 °C {68 °F}]
•  If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

5.  Install in the reverse order of removal.


Spool Valve Operation Inspection

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2.  Remove the plug hole plate. (See PLUG HOLE PLATE REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

3.  Remove the ignition coil. (See IGNITION COIL/ION SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

4.  Remove the cylinder head cover. (See TIMING CHAIN REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

5.  Remove the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

6.  Verify that the spool valve in the OCV is in the maximum valve timing retard position as indicated in the figure.

•  If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

7.  Verify that the battery is fully charged. (See BATTERY INSPECTION.)

•  If not as specified, recharge the battery. (See BATTERY RECHARGING.)

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 not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

9.  Stop applying battery positive voltage and verify that the spool valve returns to the maximum valve timing retard position.

•  If not as specified, replace the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

10.  Install the OCV. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)


SKYACTIV-G 1.5 (With 4-2-1 Exhaust System)


Coil Resistance Inspection
