P0340 CMP SENSOR (PHASE)
DescriptionINFOID:0000000001693299
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.

NOTE:
If DTC P0340 is displayed with DTC P1129, first perform the trouble diagnosis for DTC P1129. Refer to
EC-551, "

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
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.
>> 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.

2.CHECK INTERNAL FUEL TRANSFER PUMP
1. Turn ignition switch OFF.
2. Disconnect the return system connections at the fuel injectors and close off the return pipes so they are
leak-tight.
3. To authorise a 15 second cranking engine and carry out this test it is essential to carry out the following
procedure:
- Disconnect high pressure supply pump (volumetric control valve) harness connector
- Turn ignition switch ON.
- Perform “SAVE DATA FOR CPU REPLC” in WORK SUPPORT mode with CONSULT-III.
- Perform “PRGRM REINITIALIZE” in WORK SUPPORT mode with CONSULT-III.
- Cranking engine for at least 15 seconds (starting speed 250 rpm)
- Perform “WRT DATA AFTR REPLC CPU” in WORK SUPPORT mode with CONSULT-III.
Is the return volume at the fuel injectors more than 20 ml per fuel injector for the starting phase?
NOTE:
Do not repeat this procedure more than 3 times and wait 30 seconds between each 15 second cranking
engine.
Then wait 30 minutes before cranking the engine for 3 15 second cycles.
Follow this instruction so that the starter does not get damaged.
Does the flow measure more than 20ml?
Yes >> Replace malfunctioning fuel injector.
No >> GO TO 3.
3.CHECK FUEL INJECTOR-II
1. Turn ignition switch OFF.
2. Reconnect return pipes.
3. Start Engine.
4. Select “DATA MONITOR” mode with CONSULT-III.
5. Check “RAIL PRESSURE” and “RAIL PRES SET” indication.
6. Does “RAIL PRESSURE” follow “RAIL PRES SET” during the 3 second cranking engine?
Is the inspection result normal?
YES >> GO TO 5.
NO >> GO TO 4.
4.CHECK GLOW PLUG
1. Turn ignition switch OFF.
2. Remove the glow plugs and check for moisture.
3. If the glow plugs are wet with fuel, it is possible that the fuel injector is leaking.
Are the glow plugs wet with fuel?
Yes >> Replace malfunction fuel injector.
No >> Replace high pressure supply pump.
5.INSPECTION END
Fuel injector system OK.
