INSPECTION
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.

INSPECTION
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).
