DTCP1349VVT SYSTEM MALFUNCTION (BANK 1)
CIRCUIT DESCRIPTION
VVT system controls the intake valve timing to proper timing in response to\
driving condition.
The ECM controls the oil control valve (OCV) to make the intake valve timing properly, oil pressure regulated
by the OCV is supplied to the valiable valve timing (VVT) controller, and then the VVT controller changes
relative position between the camshaft and the crankshaft.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using \f \b\f\f
 Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.

2PERFORM ACTIVE TEST BY HAND±HELD TESTER(OPERATE OF OCV)
(a)Start the engine and warm it up.
(b)Connect the hand±held tester and select VVT from the ACTIVE TEST menu\
.
(c)Check the engine speed while operating the OCV by the hand±held teste\
r.
OCV is OFF: Normal engine speed
OCV is ON: Rough idle or engine stall
HINT:
DTC P1349 is also output when a foreign object is detected in some parts\
of the system in engine oil, and
then the system returns to normal in a short time. There is also no problem \
on the VVT as the oil filter should
catch the foreign object in engine oil.

3INSPECT ECM(CHECK VOLTAGE)
(a)Turn the ignition switch ON.
(b)Check the waveform between terminals OCV+ and OCV± of the E13 ECM connector.
HINT:

The correct waveform is as shown on the left.

The waveform frequency (A) becomes longer as the en-
gine speed becomes higher.

CIRCUIT DESCRIPTION
HINT:

If DTC P1300 is displayed, check No.1 ignition coil with igniter circuit.

If DTC P1305 is displayed, check No.2 ignition coil with igniter circuit.

If DTC P1310 is displayed, check No.3 ignition coil with igniter circuit.

If DTC P1315 is displayed, check No.4 ignition coil with igniter circuit.
A Direct Ignition System (DIS) has been adopted. The DIS improves the ignition timing accuracy, reduces
the high±voltage loss, and enhances overall reliability of the ignition system by eliminating the distributor.
The DIS is a 1±cylinder ignition system which ignites one cylinder with one ignition coil. In the 1±cylinder
ignition system, the spark plug is connected to the end of the secondary coil. High voltage generated in the
secondary coil is applied directly to the spark plug. The spark of the spark plug passes through from the cen-
ter electrode to the ground electrode.
The ECM determines ignition timing and outputs the ignition (IGT) signals of each cylinder. Based on IGT
signals, the power transistors cut off the current to the primary coil in the ignition coil. At the same time, the
igniter also sends an ignition confirmation (IGF) signal as a fail±safe measurement to the ECM.
