Fault analysis method for a lambda probe
A fault analysis method for a lambda probe of an internal combustion engine, in particular for detecting a heater input, has the following steps: measurement of an air ratio in the exhaust gas of the internal combustion engine by a lambda probe, control of the air ratio in the exhaust gas of the int...

| description | A fault analysis method for a lambda probe of an internal combustion engine, in particular for detecting a heater input, has the following steps: measurement of an air ratio in the exhaust gas of the internal combustion engine by a lambda probe, control of the air ratio in the exhaust gas of the internal combustion engine by a lambda probe by a lambda controller intervention in accordance with the measured air ratio, and evaluation of the lambda controller intervention in order to detect a fault. |
