Tester OperationSpecified Condition
OCV is OFFNormal engine speed
OCV is ONRough idle or engine stall
OK VVT system is OK.*
*: DTC P0011, P0012, P0021 or P0022 is also output when a
foreign object is detected in some parts of the system in the en-
gine oil, and then the system returns to normal in a short time.
As ECM is controlled to eject a foreign object, there is no prob-
lem on the VVT. There is also no problem on the VVT as the oil
filter should catch the foreign object in the engine oil.
