HINT:
*: When cranking the engine, each cylinder measures the
engine rpm.
In this ACTIVE TEST, the fuel and ignition of all cylinders is
cut, and cranking occurs for approximately 10 seconds. Then,
each cylinder measures the engine rpm. If a cylinder's engine
rpm is higher than the others, that cylinder's compression
pressure is compared to the others, and whether or not the
compression pressure is low can be determined.
1. Warm up the engine.
2. Turn the ignition switch OFF.
3. Connect the intelligent tester to the DLC3.
4. Turn the ignition switch ON and turn the intelligent tester
ON.
5. Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / ACTIVE TEST / COMPRESS
CHECK.
HINT:
If the results are not displayed normally, select the display
items from the DATA LIST before performing the ACTIVE
TEST. Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DATA LIST / USER DATA / ENG
SPEED #1 and ENG SPEED #2, ENG SPEED #3, ENG
SPEED #4 (Press the YES button to change the ENG
SPEED #1 to #4 is YES) and then press the ENTER
button.
6. While the engine is not running, press the RIGHT or LEFT
button to change the COMPRESS CHECK to ON.
HINT:
After performing the above procedure, the ACTIVE TEST's
COMPRESS CHECK will start. Fuel injection for all
cylinders is prohibited, and the each cylinder's engine rpm
measurement will enter standby.
7. Fully open the throttle.
8. Crank the engine for about 10 seconds.
9. Monitor the engine speed (ENG SPEED #1 to #4)
displayed on the tester.
HINT:
At first, the tester's display will show each cylinder's
engine rpm measurement to be extremely high. After
approximately 10 seconds of engine cranking, each
cylinder's engine rpm measurement will change to the
actual engine rpm.
NOTICE:
• After the ACTIVE TEST's COMPRESS CHECK is
turned ON, it will automatically turn off after 255
seconds.

INSPECTION PROCEDURE
HINT:
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) Start the engine and turn the tester ON.
(c) Warm up the engine.
(d) On the tester, select the following menu items:
DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST /

MONITOR DESCRIPTION
The ECM optimizes the intake valve timing using the VVT (Variable Valve Timing) system to control the
intake camshaft. The VVT system includes the ECM, the Oil Control Valve (OCV) and the VVT controller.
The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil
pressure supplied to the VVT controller. The VVT controller can advance or retard the intake camshaft.
If the difference between the target and actual intake valve timings is large, and changes in the actual
intake valve timing are small, the ECM interprets this as the VVT controller stuck malfunction and sets a
DTC.
Example:
A DTC is set when the following conditions 1, 2 and 3 are met:
1. The difference between the target and actual intake valve timing is more than 5
CA (Crankshaft
Angle) and the condition continues for more than 4.5 seconds.
2. It takes 5 seconds or more to change the valve timing by 5
CA.
3. After above conditions 1 and 2 are met, the OCV is forcibly activated 63 times or more.
DTC P0011 (Advanced Cam Timing) is subject to 1 trip detection logic.
DTC P0012 (Retarded Cam Timing) is subject to 2 trip detection logic.
These DTCs indicate that the VVT controller cannot operate properly due to OCV malfunctions or the
presence of foreign objects in the OCV.
The monitor will run if all of the following conditions are met:
– The engine is warm (the engine coolant temperature is 75
C [167F] or more).
– The vehicle has been driven at more than 64 km/h (40 mph) for 3 minutes.
– The engine has idled for 3 minutes.

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.
