2004 ENGINE
Ignition System - Endeavor
GENERAL DESCRIPTION This system is provided with six ignition coils with built-in ignition power
transistors for each of the cylinders.
Interruption of the primary current flowing in the primary side of ignition coil
generates a high voltage in the secondary side of ignition coil.
The powertrain control module (PCM) controls the three ignition power transistors
to turn them alternately ON and OFF. This causes the primary currents in the
ignition coils to be alternately interrupted and allowed to flow to fire the cylinders
in the order 1-2-3-4-5-6.
The PCM determines which ignition coil should be controlled by means of the
signals from the camshaft position sensor which is incorporated in the camshaft and
from the crankshaft position sensor which is incorporated in the crankshaft.
It also detects the crankshaft position to provide ignition at the most appropriate
timing in response to the engine operation conditions.
When the engine is cold or operated at high altitudes, the ignition timing is slightly
advanced to
provide o
ptimum
performance.
