DTC P0340 CMP SENSOR (PHASE)
DTC P0340 CMP SENSOR (PHASE)
PFP:23731
Component DescriptionEBS00K8C
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.
On Board Diagnosis LogicEBS00K8D
DTC Confirmation ProcedureEBS00K8E
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”.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Crank engine for at least 2 seconds and run it for at least 5 sec-
onds at idle speed.
4. If 1st trip DTC is detected, go to EC-242, "
Diagnostic Procedure"
.
If 1st trip DTC is not detected, go to next step.
5. Maintain engine speed at more than 800 rpm for at least 5 sec-
onds.
6. If 1st trip DTC is detected, go to EC-242, "
Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

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.
