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.

KNOCK SENSOR (KS)
YAA1F320
The Knock Sensor (KS) detects abnormal knocking in the engine. The two KS are mounted in the engine block near
the cylinders. The sensors produce an output voltage which increases with the severity of the knock. This signal is sent
to the Engine Control Module (ECM) via a shielded cable. The ECM then adjusts the ignition timing to reduce the spark
knock.

DInspection the ECM
Circuit Description
The KS system is used to detect engine detonation, allowing the ECM to retard the ignition control spark timing based
on the KS signal being received. The KS signal’s amplitude and frequency depend upon the amount of knock being
experienced. The ECM monitors the KS signal and can diagnose the KS sensor and circuitry.
Knock Sensor Resistance Inspection
1. Disconnect the coupling from ECM while the ignition switch is in “OFF” position.
2. Measure the resistance between the coupling terminal pin No. 118 and No. 117 and terminal pin No. 115 and No.

Notice:Replace the KS if the measured values is out of the specified values. Check the connector and wire connec-
tion between ECM and the KS if the measured values are normal.

Circuit Description
The ECM monitors the crankshaft and camshaft positions to detect if the engine is misfiring. The ECM looks for a quick
drop in crankshaft speed. Misfire multiple cylinder is monitored by engine roughness measuring. The actual roughness
value is compared with the actual (emission and catalyst damage) threshold.

Intake Air Temperature
The Intake Air Temperature (IAT) sensor is a part of Hot Film Air Mass (HFM) sensor and is a thermistor, a resistor
which changes value based on the temperature of the air entering the engine. Low temperature produces a high resist-
ance, while high temperature causes a low resistance as the following table.
The ECM provides 5 volts to the IAT sensor through a resistor in the ECM and measures the change in voltage to
determine the IAT. The voltage will be high when the manifold air is cold and low when the air is hot. The ECM knows
the intake IAT by measuring the voltage.
The IAT sensor is also used to control spark timing when the manifold air is cold.
