P0340 CMP SENSOR (PHASE)
Component Description
INFOID:0000000005273195
The camshaft position sensor (PHASE) senses the retraction with
camshaft (intake) to identify a particular cylinder. The camshaft posi-
tion 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.

DTC Confirmation Procedure
INFOID:0000000005273197
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-III
1.
Crank engine for at least 2 seconds and run it for at least 5 seconds at idle speed.
2.
Check 1st trip DTC.
3.
If 1st trip DTC is detected, go to
If 1st trip DTC is not detected, go to next step.
4.
Maintaining engine speed at more than 800 rpm for at least 5 seconds.
5.
Check 1st trip DTC.
6.
If 1st trip DTC is detected, go to

Camshaft position sen-
sor (PHASE) circuit
• The cylinder No. signal is not sent to ECM for
the first few seconds during engine cranking.
• The cylinder No. signal is not set to ECM dur-
ing engine running.
• The cylinder No. signal is not in the normal
pattern during engine running.
• Harness or connectors
(The sensor circuit is open or shorted)
• Camshaft position sensor (PHASE)
• Camshaft (Intake)
• Starter motor (Refer to
• Starting system circuit (Refer to
.)
• Dead (Weak) battery
