INSPECTION PROCEDURE
HINT:
Abnormal bank
Bank 1
Bank 2
• If DTC P0011 or P0012 is displayed, check the right bank VVT system for intake camshaft circuit (bank
1).
ES
• 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.
• 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 (See page ES-45).
