FUNCTION AND OPERATION PRICIPLE
The CVVT Oil Temperature Sensor (OTS) is a negative coefficient thermistor used by the PCM tl measure engine oil
temperature for the purpose of adjusting CVVT calculations.

INSPECTION
FUNCTION AND OPERATION PRICIPLE
Crankshaft Position Sensor (CKPS) detects the crankshaft position and is one of the most important sensors of the
engine control system. If there is no CKPS signal input, fuel is not supplied and the main relay does not operate. That
is, vehicle can't run without CKPS signal. This sensor is installed on transaxle housing and generates alternating
current by magnetic flux field which is made by the sensor and the target wheel when engine runs. The target wheel
consists of 58 slots and 2 missing slots on 360 CA (Crank Angle).

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.

INSTALLATION
If the OCVs are installed incorrectly, the vehicle may be damaged.
So when installing them, ensure the OCV and harness connector colors match(Components and harness side).

INSPECTION
FUNCTION AND OPERATION PRICIPLE
The Continuously Variable Valve Timing (CVVT) system controls the amount of valve overlap by varying the amount of
oil flow into an assembly mounted on each intake camshaft through PCM control of an oil control valve. This system
uses two oil control valves, one on each bank. An Oil Temperature Sensor (OTS) is used to allow PCM monitoring of
engine oil temperature. As oil is directed into the chambers of the CVVT assembly, the cam phase is changed to suit
various performance and emissions requirements.. 1. When camshaft rotates engine rotation- wise: Intake- Advance / Exhaust- Retard
2. When camshaft rotates counter engine rotation- wise: Intake- Retard / Exhaust- Advance

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).
