Tests
If the O2 calibration is possible despite the expired O2 sensor cell, the O2
measurement will continue to be available. With an expired O
2 sensor cell, a yellow
test result (operational with limitations) can be achieved at best.
Replace the sensor cell when the O
2 sensor can no longer be calibrated, see
page 55.
