DTC P0335 CKP SENSOR (POS)
Component Description INFOID:0000000004500150
The crankshaft position sensor (POS) is located on the cylinder
block rear housing facing the gear t eeth (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 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. The ECM
receives the voltage signal and detects the fluctuation of the engine
revolution.
ECM receives the signals as shown in the figure.

DTC P0340 CMP SENSOR (PHASE)
Component Description INFOID:0000000004500158
The camshaft position sensor (PHASE) senses the protrusion of
camshaft (INT) to identify a particular cylinder. The camshaft position
sensor (PHASE) senses the pist on position. When the crankshaft
position sensor (POS) system becomes inoperative, the camshaft
position sensor (PHASE) provides various controls of engine parts
instead, utilizing timing of cylinder identification signals. The sensor
consists of a permanent magnet and Hall IC. When engine is run-
ning, the high and low parts of the teeth cause the gap with the sen-
sor 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.
ECM receives the signals as shown in the figure.
