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.

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, "

Fuel Filter
DESCRIPTIONNJEC0623A water draining cock is on the lower side and a priming pump for
bleeding air is on the upper side.
SEF375Y
AIR BLEEDINGNJEC06241. After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.
2. To start the engine, rotate the starter for a maximum of 30
seconds. To start the engine more quickly, crank the engine
while pumping the priming pump (requires two workers).
3. If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.
4. Rotate the starter again until the engine starts running.
5. After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.
When air is bled completely, the pumping of the priming
pump suddenly becomes heavy. Stop the operation at that
time.
If it is difficult to bleed air by the pumping of the priming
pump (the pumping of the priming pump does not become
heavy), disconnect the fuel supply hose between the fuel
filter and the injection pump. Then, perform the operation
described above, and make sure that fuel comes out. (Use
a pan, etc. so as not to spill fuel. Do not let fuel get on
engine and other parts.) After that, connect the hose, then
bleed air again.
Start engine and let it idle for at least one minute after
performing air bleeding.
WATER DRAININGNJEC06251. Remove the fuel filter, filter bracket, protector assembly from
the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and
vacuum hose for brake booster (between the vacuum pump
and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape,
etc. to prevent foreign object from getting into the engine
during the operation.
b. Disconnect the water level warning sensor harness connector.
c. Remove the mounting nuts on the dash panel, then remove the
fuel filter, filter bracket, and protector assembly from the dash
panel.
It is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock
at the bottom of the water level warning sensor located under
the fuel filter.
