This item is short−term fuel com-
pensation used to maintain air−fuel
ratio at stoichiometric air−fuel ratio
This item is overall, long−term fuel
compensation that helps to main-
tain air−fuel ratio at stoichiometric
air−fuel ratio (steadies long term
deviations of short−term fuel trim
from central value)

S OL: Open Loop−has not yet sa-
tisfied conditions to go closed
loop.
S CL: Closed Loop−using oxygen
sensor (s) as feed back for fuel
control.
S OL DRIVE: Open loop due to
driving conditions (Power enrich-
ment, deceleration enlargement).
S OL FAULT: Open loop due to de-
tected system fault.
S CL FAULT: Closed loop, but fault
with at least one oxygen sensor
may be using single oxygen sen-
sor for fuel control.
FC IDL = "ON" when throttle valve
fully closed and engine speed is
over 1,500 rpm.
