HINT:
• *1: If no idling conditions are specified, the transmission
gear selector lever should be in the N or P position, and
the A/C switch and all accessory switches should be OFF.
• *2: DATA LIST values are only displayed when performing
the following ACTIVE TEST: VVT B1. For other ACTIVE
TESTs, the DATA LIST value will be 0.
2. ACTIVE TEST
HINT:
Performing an ACTIVE TEST enables components
including the relays, VSV (Vacuum Switching Valve) and
actuators, to be operated without removing any parts.
The ACTIVE TEST can be performed with the intelligent
tester. Performing the ACTIVE TEST as the first step of
troubleshooting is one method of shortening diagnostic
time.
DATA LIST can be displayed during ACTIVE TEST.
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON.

TYPICAL ENABLING CONDITIONS
TYPICAL MALFUNCTION THRESHOLDS
Advanced camshaft timing:
Retard camshaft timing:
If the difference between the target and actual camshaft timings is greater than the specified value, the
ECM operates the VVT actuator.
Then, the ECM monitors the camshaft timing change for 5 seconds.
WIRING DIAGRAM
Refer to DTC P0010 (see page ES-64).
INSPECTION PROCEDURE
NOTICE:
DTC P0011 or P0012 may be set when foreign objects in the engine oil are caught in some parts of
the system. The DTC will remain set even if the system returns to normal after a short time.
Foreign objects are filtered out by the oil filter.
HINT:
If DTC P0011 or P0012 is present, check the VVT (Variable Valve Timing) system.
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when
malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was
moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other
data from the time the malfunction occurred.
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON.
(c) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT CODES.
(d) Read DTCs.
