Revision: June 20062007 Versa
DTC P0340 CMP SENSOR (PHASE)PFP:23731
Component DescriptionUBS00QHH
The camshaft position sensor (PHASE) senses the protrusion of
camshaft (INT) to identify a particular cylinder. The camshaft position
sensor (PHASE) senses the piston 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.
CONSULT-II Reference Value in Data Monitor ModeUBS00RWN
Specification data are reference values.
On Board Diagnosis LogicUBS00QHI
NOTE:
If DTC P0340 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.

DTC P0441 EVAP CONTROL SYSTEMPFP:14950
System DescriptionUBS00QHS
NOTE:
If DTC P0441 is displayed with other DTC such as P2122, P2123 P2127, P2128, P2138, first perform
trouble diagnosis for other DTC.
In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions.
Purge volume is related to air intake volume. Under normal purge conditions (non-closed throttle), the EVAP
canister purge volume control solenoid valve is open to admit purge flow. Purge flow exposes the EVAP con-
trol system pressure sensor to intake manifold vacuum.
On Board Diagnosis LogicUBS00QHT
Under normal conditions (non-closed throttle), sensor output voltage indicates if pressure drop and purge flow
are adequate. If not, a malfunction is determined.
