Check the pipe between the secondary air combination valve and cylinder head.

QUESTION

Is there damage, clog or disconnection of the pipe?

Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

NOTE:

In this case, temporary poor contact of connector may be the cause.
