FUEL SYS #1
Fuel system status (Bank1):
OL or CL or OL DRIVE or
OL FAULT or CL FAULT
CL: Idling after warming up
OL (Open Loop): Has not yet sa-
tisfied conditions to go closed
loop
CL (Closed Loop): Using heated
oxygen sensor as feedback for
fuel control.
OL DRIVE: Open loop due to
driving conditions (fuel enrich-
ment)
OL FAULT: Open loop due to de-
tected system fault
CL FAULT: Closed loop but
heated oxygen sensor, which
used for fuel control malfunction-
ing
