P0340 CMP SENSOR (PHASE)
P0340 CMP SENSOR (PHASE)
Description INFOID:0000000004780162
The camshaft position sensor (P HASE) 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.

If DTC P0340 is displayed with DTC P0643, first pe rform the trouble diagnosis for DTC P0643. Refer to

DTC CONFIRMATION PROCEDURE 1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conduc ted, 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 10.5 V with igni-
tion switch ON.
>> GO TO 2. 2.
PERFORM DTC CONFIRMATION PROCEDURE-I
1. Start engine and let it idle for at least 5 seconds. If engine does not start, crank engine for at least 2 seconds.
2. Check 1st trip DTC. PBIA9875J

DTC DETECTION LOGIC
NOTE:
If DTC P0442 is displayed with DTC P0456, first pe rform the trouble diagnosis for DTC P0456. Refer to
EC-335, " DTC Logic " .
This diagnosis detects leaks in the EVAP purge line using engine intake manifold vacuum.
If pressure does not increase, the ECM will check for l eaks in the line between the fuel tank and EVAP canister
purge volume control solenoid valve, under the following “Vacuum test” conditions.
The EVAP canister vent control valve is closed to s hut the EVAP purge line off. The EVAP canister purge vol-
ume control solenoid valve will then be opened to depressurize the EVAP purge line using intake manifold
vacuum. After this occurs, the EVAP canister purge volume control solenoid valve will be closed.
CAUTION:
• Use only a genuine NISSAN fuel filler cap as a replacemen t. If an incorrect fuel filler cap is used, the
MIL may come on. DTC No. Trouble diagnosis name DTC detecting condition Possible cause
