Oxygen Control

Check function:
[D] 100 - Prerequisite for this procedure is that the oxygen sensor is at operating temperature. The engine must run for 30...40 sec. before the control is implemented.

The control can compensate for wear-related deviations in the mixture compensation and therefore conceal other defects. If necessary, disconnect the oxygen sensor during troubleshooting of the mixture composition.
