DTC P0340, P0345 CMP SENSOR (PHASE)PFP:23731
Component DescriptionNBS004Z4
The camshaft position sensor (PHASE) senses the retraction 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 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.
ECM receives the signals as shown in the figure.
CONSULT-II Reference Value in Data Monitor ModeNBS004Z5
Specification data are reference values.
On Board Diagnosis LogicNBS004Z6
DTC Confirmation ProcedureNBS004Z7
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V with igni-
tion switch ON.
WITH CONSULT-II
1. Turn ignition switch ON.
