Diagnostic Note
Overall fuel compensation carried
out in long-term to compensate for
continual deviation of short-term
fuel trim from central value
• OL (Open Loop): Has not yet
satisfied conditions to go
closed loop
• CL (Closed Loop): Using A/F
sensor as feedback for fuel
control
• OL DRIVE: Open loop due to
driving conditions (fuel
enrichment)
• OL FAULT: Open loop due to
detected system fault
• CL FAULT: Closed loop but A/
F sensor, which used for fuel
control malfunctioning
• OL (Open Loop): Has not yet
satisfied conditions to go
closed loop
• CL (Closed Loop): Using A/F
sensor as feedback for fuel
control
• OL DRIVE: Open loop due to
driving conditions (fuel
enrichment)
• OL FAULT: Open loop due to
detected system fault
• CL FAULT: Closed loop but A/
F sensor, which used for fuel
control, malfunctioning
