COMPONENTS
DLC3 Connector16 pin DLC 3 connector is there for connection of diagnostic kit e.g. launch, Carman, JBT etc. for diagnosis.
MIL Blinking may also be used for diagnosis by connecting 13 and 4 number pin of DLC Connector

MED
COMPONENTSCrankshaft Position SensorIt is a pickup coil type sensor which detects the engine speed and performs the cylinder identification
Camshaft Position Sensor It is a pickup coil type sensor which performs the cylinder identification and camshaft’s position
8
MED
COMPONENTSKnock Sensor It is a non-resonant flat type sensor which detects an occurrence of the engine knocking indirectly from the vibration of the cylinder block caused by the occurrence of engine knocking
Throttle Position Sensor It is a non-contact type sensor mounted on the throttle body to detect the opening angle of the throttle valve
9
MED
COMPONENTSEngine Coolant Temp SensorIt is a thermistor type sensor which detects the engine coolant temp
Mass Air Flow sensorIt is a Hot-wire Type sensor having a built-in hot-wire to directly detect the intake air mass and temp

MED
COMPONENTSAir Fuel Ratio Sensor (1st Oxygen)It is a Planar type with Heater sensor to detects the oxygen concentration in the exhaust emission. However, it detects the oxygen concentration in the exhaust emission linearly before catalytic convertor
2nd Oxygen sensorIt is a Cup Type with Heater to detect the oxygen concentration in the
exhaust emission by measuring the electromotive force which is generated in the sensor itself.

MED
COMPONENTSInjectorsFuel injector opens and sprays the pressurized fuel into the engine. The duration that the injector is open (called the pulse width) is proportional to the amount of fuel delivered.
Each cylinder is having separate fuel injector

MED
COMPONENTSIgnition CoilsA DIS (Direct Ignition System) is used in which one ignition coil for each cylinder. The DIS ensures the ignition timing accuracy, reduces high-voltage loss, and realizes the overall reliability of the ignition system by eliminating the distributor
Spark PlugsLong-reach type iridium-tipped spark plugs are used. Spark plug caps, which connect to the spark plugs, are integrated with the ignition coils for air fuel mixture combustion

MED
COMPONENTSIdle Speed Con ValveIt is placed on throttle body to sense and set engine idle speed. Cold engine with more idling and once engine comes to normal operating temperature idling at low RPM is set by ISC valve
