F0: DATA LIST
Note: Via the 02 BLM PART THR. , learned deviations from the ideal mixture (e.g., caused by an air leak) are detected by the control unit and stored in the permanent memory. The learning process only occurs when oxygen control is active and the engine is operating normally. The 02 BLM PART THR. is effective in the entire characteristic curve range, but predominantly in the lower engine speed range. The correction values learned by the system are stored in a permanent memory and are thus always available, even if the supply voltage has been cut off and the engine has then been switched on again. Using the 02 BLM IDLE THR. , the values learnt by the system can be evaluated.
To evaluate a deviation of the 02 BLM PART THR. , the 02 INTEGRATOR must be observed.
If this is also outside the tolerance range, a statement about the engine mixture condition can be made.
