DTC P0340 CAMSHAFT POSITION (CMP) SENSOR (PHASE)
Revision: 2006 January2006 M35/M45
DTC P0340 CAMSHAFT POSITION (CMP) SENSOR (PHASE)PFP:23731
Component DescriptionNBS005GL
The camshaft position sensor (PHASE) senses the protrusion of
exhaust valve cam sprocket 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.

The cylinder No. signal is not sent to ECM
for the first few seconds during engine

DTC P1212 TCS COMMUNICATION LINE
Revision: 2006 January2006 M35/M45
DTC P1212 TCS COMMUNICATION LINEPFP:47850
DescriptionNBS005KM
NOTE:
If DTC P1212 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-886, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
If DTC P1212 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010.
Refer to EC-889, "
DTC U1010 CAN COMMUNICATION" .
This CAN communication line is used to control the smooth engine operation during the TCS operation. Pulse
signals are exchanged between ECM and “ABS actuator and electric unit (control unit)”.
Be sure to erase the malfunction information such as DTC not only for “ABS actuator and electric unit
(control unit)” but also for ECM after TCS related repair.
On Board Diagnosis LogicNBS005KN
Freeze frame data is not stored in the ECM for this self-diagnosis. The MIL will not light up for this self-
diagnosis.
DTC Confirmation ProcedureNBS005KO
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V at idle.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for at least 10 seconds.
4. If 1st trip DTC is detected, go to EC-1238, "
Diagnostic Proce-
dure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.
Diagnostic ProcedureNBS005KP
Go to BRC-11, "TROUBLE DIAGNOSIS" .
