- Check the lambda probe voltage shown in
display block 3. The voltage must vary at
least 30 times a minute within the range

If the specifications are not achieved:
K - Unplug connector -1- from the coolant
temperature sender (G62) -2-. The probe
voltage must rise and drop again to the
former control range.
- Plug in connector again. Lambda probe
voltage must drop and rise again.
If the voltage change is slower, determine the
cause ⇒ 24-12.
Note:
The throttle valve must not be operated during
the test otherwise the control unit will detect the
unplugged connector as a fault.
