Ignition System

2007 > 2.7L V6 GASOLINE >
DESCRITION
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. Remove the ignition coil (A).
3.Remove the ignition coil.
4. Installation is the reverse of removal.
REPLACEMENT
SPARK PLUG
1. Remove the ignition coil connector(A).
2.Remove the ignition coil.
3. Using a spark plug socket, remove the spark plug.
Be careful that no contaminates enter through the spark plug holes

ON-VEHICLE INSPECTION
SPARK TEST
1. Remove the ignition coil connector(A).
Disconnect the iguition coil connector while pulling up tre connector lock.
2. Remove the ignition coil.
3. Using a spark plug socket, remove the spark plug.
4. Install the spark plug to the ignition coil.
5. Ground the spark plug to the engine.
6.Check is spark occurs while engine is being cranked.
