OVERALL FUNCTION CHECK
Instead of performing the Diagnostic Trouble Code (DTC) Detecting Condition, the following method can be used for checking the function of the closed loop control. The "NG" of this check means the same as the DTC detection.
1) Start engine and warm it up sufficiently.




2) Select "FR O2 MNTR-B1 (B2)" in "DATA MONITOR" mode with CONSULT.
3) Maintaining engine at 2,000 rpm under no-load, check to make sure that the monitor fluctuates between "LEAN" and "RICH" more than 5 times during 10 seconds.
