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 (2 -- 3 or 1 -- 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 requires
very little of the available energy to fire the spark plug. The remaining energy is available to the spark plug in the cylin-
der 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
YAA1F920
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 1 and 4
T1/2: cylinder 2 and 3
The EI system ignition coil is not serviceable and must be replaced as an assembly.

DInspection the ECM
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
YAA1F940
This Electronic Ignition (EI) system uses inductive or pickup 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.

Injector Spray Pattern Check
1. Turn the ignition switch OFF.
2. Remove the fuel injector connectors.
3. Remove the fuel distributor and injector with a unit. At this time, do not remove the supply and return line.
Notice:Prepare the beaker for taking the fuel.
4. Connect the shop made cable to the injector with a firing order.
5. Connect the other end of shop made cable to the positive battery cable and negative battery cable.
6. Turn the ignition switch ON.
7. Check the injector for normal spray pattern as shown in the figure. Check injector for leaks or later drop
Injector Resistance Inspection
1. Turn the ignition switch OFF.
2. Remove the fuel injector connectors.
3. Measure the fuel injector coil resistance using a multimeter.
Specified Value
14 ~ 17Ω
Notice:Replace the fuel injector if the measured value is out of the specified values. Check the connector and wire
connection between the ECM and the injector if the measured values are normal.

Circuit Description
Ignition voltage is supplied directly to the cooling fan relay coil. The ECM controls the relay by grounding the control
circuit. When the ECM is commanding a command ON, the voltage of the control circuit should be low (near 0 volt).
When the ECM is commanding the control circuit should be high (near battery voltage). If the fault detection circuit
senses a voltage other than what is expected, the fault line status will change causing the fault code to set.
