DIAGNOSTIC NOTE
Air-fuel ratio feedback learning is
divided up according to the
engine operating range (engine
speed x load), and separate
values are stored for each
operating range. "Long FT #2"
indicates the learned value for the
current operating range. [A/F
Learn Value Idle #2], [A/F Learn
Value Low #2], [A/F Learn Value
Mid1 #2], [A/F Learn Value Mid2
#2] and [A/F Learn Value High
#2] indicate the leaned values for
the different operating ranges.
The learned value that is the
same as "Long FT #2" indicates
the current engine operating
range.
