Sensor wheel learning value

NOTE:
- To monitor and/or record combustion misfiring, a sensor wheel is necessary. The flywheel (starter ring gear) is used as the sensor wheel. The flywheel is checked for mechanical damage after each start, i.e. specified tolerances must not be exceeded.
- Small malfunctions in the flywheel (e.g. teeth worn) are compensated by learning values. If greater damage is recognized, the malfunction "engine speed sensor wheel tooth error recognized" is stored in the DTC memory.
- The sensor wheel is tested during a deceleration fuel shut-off in the engine speed range from 2200-4000 RPM. In order to get a result, the length of the deceleration fuel shut off must be approx. 10 sec.
