·     Engine running at idle speed

       Coolant temperature higher than 40 °C / 104 °F (C 18 XE) or higher than 31 °C / 88 °F (X 20 XEV)

       or

       Engine running in load range

       Coolant temperature higher than 45 °C / 113 °F (C 18 XE) or higher than 31 °C / 88 °F (X 20 XEV)

·     Control unit has recognized at least 30 lean - rich - lean changes (oxygen sensor jumps) at the oxygen sensor input

·     Difference between average maximum and average minimum oxygen sensor voltage is less than 1.0 V (oxygen sensor voltage variation too small)

·     Conditions must be fulfilled for at least 5.0 s

 

Effects:

·     The oxygen sensor control and tank vent valve control are blocked

·     The tank vent valve is actuated to a minimum value.
