DTC P0335 CKP SENSOR (POS)
PFP:23731
Component DescriptionEBS00KHN
The crankshaft position sensor (POS) is located on the cylinder
block rear housing facing the gear teeth (cogs) of the signal plate at
the end of the crankshaft. It detects the fluctuation of the engine rev-
olution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

DTC P0340 CMP SENSOR (PHASE)PFP:23731
Component DescriptionEBS00KHV
The camshaft position sensor (PHASE) senses the retraction with
intake valve camshaft to identify a particular cylinder. The camshaft
position sensor (PHASE) senses the piston position.
When the crankshaft position sensor (POS) system becomes inoper-
ative, the camshaft position sensor (PHASE) provides various con-
trols of engine parts instead, utilizing timing of cylinder identification
signals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor changes.

COOLING FAN CONTROL
*1: The ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: These signals are sent to the ECM through CAN communication line.
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, refrigerant
pressure, and air conditioner ON signal. The control system has 2-step control [ON/OFF].
The ECM sends a cooling fan control signal to the smart entrance control unit through CAN communication
line, and the smart entrance control unit controls cooling fan relay.
