2008 ENGINE

Ignition System - Sedona

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.

REMOVAL

IGNITION COIL

1. Remove the engine cover.

2. Disconnect the ignition coil connector (A).
