Visual Inspection

Note

• Because the ion sensor is integrated in the ignition coil, replacing the ion sensor includes replacement of the ignition coil/ion sensor.

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

2.Remove the ignition coil/ion sensor. (See IGNITION COIL/ION SENSOR REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

3.Verify that there is no damage to the ignition coil/ion sensor, and no corrosion and damage to the connector.

• If there is a malfunction, replace the ignition coil/ion sensor. (See IGNITION COIL/ION SENSOR REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
