the value drops below 6.0 mV. The oxygen sensor should there‐
fore be replaced when this value is reached. An exact measure‐
ment is no longer possible if the probe voltage falls below the
minimum value of 5.0 mV (fault message "Sensitivity of O
sor too low").
• The reading (actual value) is the probe voltage measured on
the sensor during the last AUTOCAL.

sage is output when fallen below.
