ABSTRACT:
Fault detection in a feedback air/fuel ratio control system using an exhaust gas oxygen sensor compares the expected transport delay time to the time between exhaust gas oxygen sensor output level switching. A fuel system failure is determined when there is an inappropriate switching rate of the oxygen sensor output level.
