INSPECTION PROCEDURE
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.

Read freeze frame data using TOYOTA hand±held tester or OBD II scan tool. Because freeze frame
records the engine conditions when the malfunction is detected, when troubleshooting it is useful for
determining whether the vehicle was running or stopped, the engine warmed up or not, the air±fuel
ratio lean or rich, etc. at the time of the malfunction.

2 Check operation of OCV.
PREPARATION:
(a) Start the engine and warmed it up.
(b) Connect the TOYOTA hand±held tester and select VVT from ACTIVE TEST menu.
CHECK:
Check the engine speed when operate the OCV by the TOYOTA hand±held tester.
OK:
VVT system OFF to ON (OCV OFF to ON):
Engine speed increases.
VVT system ON to OFF (OCV ON to OFF):
Engine is stalled.
HINT:
The change of engine speed lasts only few seconds.
OK VVT system is OK.*
*: DTC P1349 is also output after the foreign object is caught
in some part of the system in the engine oil and the system re-
turns to normal in a short time. As ECM controls so that foreign
objects are ejected, there is no problem about VVT. There is
also no problem since the oil filter should get the foreign object
in the engine oil.

3 Check voltage between terminals OCV+ and OCV± of ECM connector.
Reference: INSPECTION USING OSCILLOSCOPE
Turn the ignition switch ON, check waveform between terminals
OCV+ and OCV± of the ECM connector.
HINT:

The correct waveform is as shown.

The waveform frequency (A) is lengthened as the engine
speed becomes higher.
NG Check and replace ECM (See page IN±41).
OK

7 Check whether or not DTC P1349 is stored.
PREPARATION:
(a) Clear the DTC (See page DI±3).
(b) Perform simulation test.
CHECK:
Check whether or not DTC P1349 is stored (See page DI±3).
OK:
DTC P1349 is not stored
OK VVT system is OK.*
