3) After above conditions 1) and 2) are met, the OCV is forcibly activated 63 times or more.
DTCs P0011 and P0021 (Advanced Cam Timing) are detected with 1 trip detection logic.
DTCs P0012 and P0022 (Retarded Cam Timing) are detected with 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 not run unless 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 40 mph (64 km/h) for 3 minutes.
- The engine has idled for 3 minutes.

INSPECTION PROCEDURE
HINT:
• If DTC P0013 is displayed, check the exhaust camshaft circuit for the bank 1 VVT system.
• Bank 1 refers to the bank that includes cylinder No. 1.
• If DTC P0023 is displayed, check the exhaust camshaft circuit for the bank 2 VVT system.
• Bank 2 refers to the bank that does not include cylinder No. 1.
• Read freeze frame data using an 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) 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.
