Functions
1. Firing order : 1 -- 5 -- 3 -- 6 -- 2 -- 4
2. The ignition cables are located on the cylinder head
cover. Each 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
3. The secondary output voltage (5a) is supplied to the
No.2 cylinder spark plug through the spark plug con-
nector. The secondary output voltage (5b) is supplied
to the No.5 cylinder spark plug through the ignition
cable. The guide pin (W) acts as a ground while the
ignition cable is operated.
Removal & Installation Procedure
1. Disconnect the negative battery cable (1).
2. Remove the ignition cable connector from the ignition
cable.
3. Disconnect the secondary spark plug connectors
from the each spark plugs and remove the ignition
cable bolt and ignition cable.
Installation Notice
Tightening Torque
9--11NSm (80 -- 97 lb-in)
DMake sure that the ignition cables are correctly
routed.
DExactly install the ignition cable guide pin into the
vehicle to be grounded.
4. Installation should follow the removal procedure in
the reverse order.

CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless other -
wise noted.

IGNITION SYSTEM
This ignition system does not use a conventional distributor andcoil. It uses a crankshaft position sensor input to the
Engine Control Module (ECM). The ECM then determines Electronic Spark Timing (EST) and triggers the electronic
ignition system ignition coil.
This type of distributorless ignition system uses a‘‘waste spark” method of spark distribution. Each cylinder is paired
with the cylinder that is opposite it (1 -- 6 or 2 -- 5 or 3 -- 4). The spark occurs simultaneously in the cylinder coming up on
the compression stroke and in the cylinder coming up on the exhaust stroke. The cylinder on the exhaust stroke re-
quires very little of the available energy to fire the spark plug. The remaining energy is available to the spark plug in the
cylinder on the compression stroke.
These systems use the EST signal from the ECM to control the EST. The ECM uses the following information:
DEngine load (mass air flow sensor).
DEngine temperature.
DIntake air temperature.
DCrankshaft position.
DEngine speed (rpm).

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.
