DTCP0340CAMSHAFT POSITION SENSOR ºAº CIRCUIT (BANK 1 OR SINGLE SENSOR)
CIRCUIT DESCRIPTION
Camshaft position sensor (G signal) consists of a magnet, iron core and pickup\
coil.
The G signal plate has one tooth on its outer circumference and is installe\
d on the camshaft timing pulley.
When the camshafts rotate, the protrusion on the signal plate and the air ga\
p on the pickup coil change,
causing fluctuations in the magnetic field and generating an electromoti\
ve force in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft timing pu\
lley. The NE signal sensor gen-
erates 34 signals at every engine revolution. The ECM detects the standard crankshaft angl\
e based on the
G signal and the actual crankshaft angle and the engine speed by the NE s\
ignal.

a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, etc. at the time of the malfu\

DTCP0200INJECTOR CIRCUIT / OPEN
HINT:

For more information on the EDU, see page 05±517.

If P0200 are present, Use the diagnostic trouble code matrix for fuel sy\
stem, see page 05±517.
CIRCUIT DESCRIPTION
The EDU has been adopted to drive the injector at high speeds. The EDU has \
realized high±speed driving
under high fuel pressure conditions using the DC/DC converter that provides a\
high±voltage, quick±charging
system.
Soon after the EDU receives an injection command signal (IJT) from the\
ECM, the EDU responds to the com-
mand with injector injection confirmation signal (IJF) when the current is\
applied to the injector.
