CIRCUIT
DTC P0339 CRANKSHAFT POSITION SENSOR ºAº
CIRCUIT INTERMITTENT
CIRCUIT DESCRIPTION
Crankshaft position sensor (NE signal) consists of a magnet, iron core and pickup coil.
The NE signal plate has 34 teeth and is installed the crankshaft timing pulley. The NE signal sensor gener-
ates 34 signals of every engine revolution. The ECM detects the standard crankshaft angle based on the
G signal, and the actual crankshaft angle and the engine speed by the NE signal.
DTC No.DTC Detection ConditionTrouble Area
P0335
No crankshaft position sensor signal to ECM during cranking
(2 trip detection logic)
P0335No crankshaft position sensor signal to ECM with engine
speed 650 rpm or more (2 trip detection logic)

INSPECTION PROCEDURE
HINT:

Perform troubleshooting of DTC P0335 first. If no trouble is found, troubleshoot the engine mechanical
systems.

Read freeze frame data using   
 . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle
was running or stopped, the engine was warmed up or not, etc. at the time of the malfunction.

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.
