2007 ENGINE PERFORMANCE On-Board Diagnostic (MZI-3.5) - CX-9
The fuel tank level should be between 1/2 and 3/4 full with 3/4 full being the
most desirable.
The evaporative emission system monitor can only operate during the first
30 min of the engine operation. When executing the procedure for the
evaporative emission system monitor, remain in part throttle position and
drive in a smooth fashion to minimize "fuel slosh".
When bypassing the EVAP soak times, the PCM must remain powered
(ignition switch to the ON position) after clearing the continuous DTCs and
relearning emission diagnostic information.
