DESCRIPTION AND OPERATION
Ignition Components, Electronic
The electronic ignition (EI) system for the 4.6L (2V)
engine consists of the following components:
•
crankshaft position sensor (CKP sensor)(6C3 15)
•
ignition coil ( 12029)
Crankshaft Position (CKP) Sensor
NOTE: Initial engine ignition timing is set at 10 degrees
± 2 degrees before top dead center (BTDC) and is not
adjustable.
The crankshaft position sensor (CKP sensor)(6C31 5)
is a variable reluctance sensor triggered by a
36-minus- 1 tooth trigger pulse wheel located on the
crankshaft (6303) inside the engine front cover
(6019).
The signal generated from the crankshaft position
sensor provides two types of information:
•
One is the position of the crankshaft in 10 degree
increments.
•
The other is the crankshaft speed (rpm).
- The powertrain control module (PCM)( 12A650)
uses this information to determine ignition coil
turn on arid turn off times.
