FUNCTION AND OPERATION PRICIPLE
Engine Coolant Temperature Sensor (ECTS) is located in the engine coolant passage of the cylinder head for
detecting the engine coolant temperature. The ECTS uses a thermistor whose resistance changes with the
temperature. The electrical resistance of the ECTS decreases as the temperature increases, and increases as the
temperature decreases. The reference 5 V in the PCM is supplied to the ECTS via a resistor in the PCM.That is, the
resistor in the PCM and the thermistor in the ECTS are connected in series. When the resistance value of the
thermistor in the ECTS changes according to the engine coolant temperature, the output voltage also changes. During
cold engine operation the PCM increases the fuel injection duration and controls the ignition timing using the
information of engine coolant temperature to avoid engine stalling and improve drivability.

FUNCTION AND OPERATION PRICIPLE
Knocking is a phenomenon characterized by undesirable vibration and noise and can cause engine damage. Knock
Sensor (KS) senses engine knocking and the two sensors are installed inside the V- valley of the cylinder block. When
knocking occurs, the vibration from the cylinder block is applied as pressure to the piezoelectric element. At this time,
this sensor transfers the voltage signal higher than the specified value to the PCM and the PCM retards the ignition
timing. If the knocking disappears after retarding the ignition timing, the PCM will advance the ignition timing. This
sequential control can improve engine power, torque and fuel economy.

FUNCTION AND OPERATION PRICIPLE
Camshaft Position Sensor (CMPS) is a hall sensor and detects the camshaft position by using a hall element. It is
related with Crankshaft Position Sensor (CKPS) and detects the piston position of each cylinder which the CKPS can't
detect. The two CMPS are installed on engine head cover of bank 1 and 2 and uses a target wheel installed on the
camshaft. This sensor has a hall - effect IC which output voltage changes when magnetic field is made on the IC with
current flow.

INSPECTION
FUNCTION AND OPERATION PRICIPLE
Based on information from various sensors, the PCM measures the fuel injection amount. The fuel injector is a
solenoid- operated valve and the fuel injection amount is controlled by length of time that the fuel injector is held open.
The PCM controls each injector by grounding the control circuit. When the PCM energizes the injector by grounding
the control circuit, the circuit voltage should be low (theoretically 0V) and the fuel is injected. When the PCM de-
energizes the injector by opening control circuit, the fuel injector is closed and circuit voltage should momentarily peak.
If an injector connector is disconnected for more than 46 seconds while the engine runs, the PCM will determine
that the cylinder is misfiring and cut fuel supply. So be careful not to exceed 46 seconds. But the engine runs
normally in 10 seconds after turning the ignition key off.

FUNCTION AND OPERATION PRICIPLE
Variable Intake manifold Solenoid (VIS) valves are installed on surge tank (VIS Valve #1) and intake manifold (VIS
Valve #2). These VIS valve #1 and #2 control vacuum modulators which activate valves in surge tank and intake
manifold. These valves are opened or closed by PCM according to engine condition (Refer to below table).
