Abstract:
Disclosed is a method for diagnosis of an oxygen probe for a combustion engine, with the steps: When an engine's fuel injection is inactive, measuring the output electric voltage from the oxygen probe; If the measured output electrical voltage of the oxygen probe is greater than a predetermined minimum voltage threshold, measuring a pressure prevailing in an intake distributor of the engine; If the measured pressure in the intake distributor is less than a predetermined minimum pressure threshold, increasing the pressure to a value greater than the predetermined minimum pressure threshold; Determining the time period between the time when the output electrical voltage of the probe falls below a second predetermined voltage threshold and the time when the output electrical voltage of the probe falls below a third predetermined voltage threshold; and diagnosing the oxygen probe depending on elapsed the time period.

Claim (Index 1):
Method for diagnosing an oxygen probe ( 14 ) of a combustion engine ( 1 ) including the following steps:\n When an engine's fuel injection ( 1 ) is inactive, measuring the output electric voltage from the oxygen probe ( 14 ) (step  51 ), If the measured output electrical voltage of the oxygen probe ( 14 ) is greater than a predetermined minimum voltage threshold (V 1 ), measuring a pressure prevailing in an intake distributor ( 8 ) of the engine ( 1 ) (step  52 ), If the measured pressure in the intake distributor ( 8 ) is less than a predetermined minimum pressure threshold (Pmini), increasing the pressure to a value greater than the predetermined minimum pressure threshold (Pmini) (step  53 ), Determining the time period (T) between the time when the output electrical voltage of the probe falls below a second predetermined voltage threshold (V 2 ) and the time when the output electrical voltage of the probe falls below a third predetermined voltage threshold (V 3 ) (step  54 ), and diagnosing the oxygen probe ( 14 ) depending on elapsed the time period (T) (step  55 ).
