IGNITION COIL
YAA1F240
The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover. The double ended coils receive
the signal for the Engine Control Module (ECM) which controls the spark advance.
Each EI system ignition coil provides the high voltage to two spark plugs simultaneously;
T1/1: cylinder 2 and 5
T1/2: cylinder 3 and 4
T1/3: cylinder 1 and 6
The EI system ignition coil is not serviceable and must be replaced as an assembly.

Circuit Description
The Electronic Ignition (EI) system uses a waste spark method of spark distribution. The Crankshaft Position (CKP)
sensor sends reference pulses to the ECM. The ECM then triggers the EI system ignition coils. Once the ECM triggers
the EI system ignition coils both of the connected spark plugs fire at the same time. One cylinder is on its compression
stroke at the same time that the other is on the exhaust stroke, resulting in lower energy needed to fire the spark plug in
the cylinder on its exhaust stroke.
This leaves the remainder of the high voltage to be used to fire the spark plug in the cylinder on its compression stroke.
Since the CKP sensor is in a fixed position, timing adjustments are not possible or needed.

CRANKSHAFT POSITION (CKP) SENSOR
YAA1F250
This Electronic Ignition (EI) system uses inductive or pick up type magnetic Crankshaft Position (CKP) sensor. The
CKP sensor is located in the opposite side of the crankshaft pulley and triggers the pick-up wheel teeth which is
equipped 60--2 teeth with a gap of 2 teeth at 360 degree spacing. This sensor protrudes through its mount to within 1.1
± 0.14 mm.
The output of the sensor is a sinusoidal signal. Each tooth of the pick-up 60 -- 2 wheel generates a positive half wave.
The Engine Control Module (ECM) uses this sensor signal to generate timed ignition and injection pulses that it sends
to the ignition coils and to the fuel injectors.
