Kia Sportage: Ignition System

Kia Sportage Third generation (SL) - (2011-2016) - Service and Repair Manual / Engine Electrical System / Ignition System

Description and Operation

 Description

Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data for the engine operating conditions are preprogrammed in the memory of the ECM (Engine Control Module).

The engine operating conditions (speed, load, warm-up condition, etc.) are detected by the various sensors. Based on these sensor signals and the ignition timing data, signals to interrupt the primary current are sent to the ECM. The ignition coil is activated, and timing is controlled.
