On my MBII scanner when I run the o2 sensor test for bank 1 sensor 1 and bank 2 sensor 1, it says the vehical does not support. I'm new to mercedes, but I thought it has 4 sensors. 2008 S550. I'd appreciate any insights.

Comments

Your car has 4 sensors. Two upstream and two downstream of each cataltyic converter. There are two cataltyic converters. All it means is that the scanner does not support bidirectional function to test the oxygen sensor. What you can do is look at live sensor data from the oxygen sensors. Compare the two upstream. Compare the values from the two downstream as well. I think the scanner should also give recomandations as well.
