Enable Conditions

ENABLE CONDITIONS

Secondary Parameters Enable Conditions
Battery voltage ≥ 10.9 V
Sub feedback In operation
Amount of intake air ≥ 8 g/s (0.28 oz/s) (CVT model)
≥ 8 g/s (0.28 oz/s) (MT model)
Estimated temperature of the rear oxygen sensor element ≥ 500 °C (932 °F) (CVT model)
≥ 500 °C (932 °F) (MT model)
Enable conditions at interrupt control are as follows
Air fuel ratio reduced from target air fuel ratio = Value of Map
Continuous time when rear oxygen sensor output voltage is less than 0.55 V ≥ 5000 ms (CVT model)
≥ 15000 ms (MT model)
