INSPECTION PROCEDURE
HINT
- If DTC P0011 or P0012 is displayed, check the intake camshaft circuit for the right bank VVT system (bank 1).
- Bank 1 refers to the bank that includes cylinder No. 1.
- If DTC P0021 or P0022 is displayed, check the intake camshaft circuit for the left bank VVT system (bank 2).
- Bank 2 refers to the bank that does not include cylinder No. 1.
- DTC P0011, P0012, P0021 or P0022 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.
- Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame
data the moment a DTC is stored. 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.
PROCEDURE
1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0011, P0012, P0021 OR P0022)

B -- GO TO DTC CHART See: Diagnostic Trouble Code Descriptions/SFI System
A -- Continue to next step.
2. PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE VVT SYSTEM (BANK 1 OR 2))
(a) Connect the Techstream to the DLC3.
