DIAGNOSTIC TROUBLE CODE CHART
HINT:
The parameters listed in the chart may not confirm exactly to
those read during the DTC check due to the type of
instrument or other factors.
If a trouble code is displayed during the DTC check in the
check mode, check the circuit for the code listed in the table
below. For details of each code, refer to the "See page"
column in the DTC chart.

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.

tester on.
(c) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT CODES.
(d) Read the DTCs.

TYPICAL MALFUNCTION THRESHOLDS
Advanced camshaft timing:
Retarded 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.
