DESCRIPTION
The Variable Valve Timing (VVT) system includes the ECM, Oil Control Valve (OCV) and 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. Camshaft timing control is performed according to engine
operating conditions such as intake air volume, throttle valve position and engine coolant temperature.
The ECM controls the OCV, based on the signals transmitted by several sensors. The VVT controller
regulates the intake camshaft angle using oil pressure through the OCV. As a result, the relative positions
of the camshaft and crankshaft are optimized, the engine torque and fuel economy improves, and the
exhaust emissions decrease under overall driving conditions. The ECM detects the actual intake valve
timing using signals from the camshaft and crankshaft position sensors, and performs feedback control.
This is how the target intake valve timing is verified by the ECM.

MONITOR DESCRIPTION
After the ECM sends the "target" duty-cycle signal to the OCV, the ECM monitors the OCV current to
establish an "actual" duty-cycle. The ECM detects a malfunction and sets a DTC when the actual duty-
cycle ratio varies from the target duty-cycle ratio.

INSPECTION PROCEDURE
HINT:
• If DTC P0010 is displayed, check the intake camshaft circuit for the right bank VVT system.
• Bank 1 refers to the bank that includes cylinder No. 1.
• If DTC P0020 is displayed, check the intake camshaft circuit for the left bank VVT system.
• Bank 2 refers to the bank that does not include cylinder No. 1.
• Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame
data can be helpful in determining whether the vehicle was running or stopped, whether the engine
was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the
time of a malfunction.
(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, enter the following menus: DIAGNOSIS /
ENHANCED OBD II / ACTIVE TEST / VVT CTRL B1 or
VVT CTRL B2.
(e) Check the engine speed while operating the Oil Control
Valve (OCV) using the tester.

HINT:
If DTC P0011, P0012, P0021 or P0022 is present, check the VVT (Variable Valve Timing) system.
DESCRIPTION
Refer to DTC P0010 (See page ES-75).
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 applied 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 actual intake
valve timing are small, the ECM interprets this as the VVT controller stuck malfunction and sets a DTC.
Example:
A DTC will be set when the following conditions 1), 2) and 3) are met:
1) The difference between the target and actual intake valve timings 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.
