COMPONENT PARTS
Ignition Coil (With Power Transistor)
INFOID:0000000009462501
The ignition signal from the ECM is sent to and amplified by the
power transistor. The power transistor turns ON and OFF the ignition
coil primary circuit. This ON/OFF operation induces the proper high
voltage in the coil secondary circuit.
Intake Valve Timing Control Solenoid ValveINFOID:0000000009462502
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.
Knock SensorINFOID:0000000009462503
The knock sensor is attached to t he cylinder block. It senses engine
knocking using a piezoelectric element. A knocking vibration from
the cylinder block is sensed as vibrational pressure. This pressure is
converted into a voltage signal and sent to the ECM.
Malfunction Indicator lamp (MIL)INFOID:0000000009462504
Malfunction Indicator lamp (MIL) is located on the combination
meter.
MIL will illuminate when the ignition switch is turned ON without the
engine running. This is a bulb check.
When the engine is started, MIL should turn OFF. If the MIL remains
illuminated, the on board diagnosti c system has detected an engine
system malfunction.

M with the lighting of MIL when a DTC is confirmed.
DIAGNOSIS DESCRIPTION : Malfunction Indicator Lamp (MIL)INFOID:0000000009462539
• When detecting a DTC that affects exhaust gas, the exhaust emis-
sion-related control module transmits a malfunction indicator lamp
signal to ECM via CAN communication line.
ECM prioritizes (MIL: ON/blink) the signal received from the
exhaust emission-related control module and the ECM-stored DTC
that affects exhaust gas and transmits a malfunction indicator lamp
signal to the combination meter via CAN communication line.
The combination meter turns ON or blinks the MIL, according to
the signal transmitted from ECM, and alerts the driver of malfunc-
tion detection.
• Control modules that a DTC of MIL ON/Blink is stored (Control module varies among DTCs.):
-ECM
-TCM
1. The MIL illuminates when ignition switch is turned ON (engine is not running). NOTE:
Check the MIL circuit if MIL does not illuminate. Refer to EC-973, "Component Function Check"
.
2. When the engine is started, the MIL should go off. NOTE:
If MIL remains ON or continues blinking, a DTC(s) t hat affects exhaust gas is detected. In this case, Self
diagnosis is required for performing inspection and repair.
