Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have a 2006 Cayman S and having trouble getting the Oxygen Sensor Monitor to come up for smog here in California. I have an OBD2 scanner that shows four entries in the "02 Monitor Test" B1S1 passed, B1S2 passed...however B3S1 and B3S2 say "the selected mode is not supported". How many O2 sensors does the Cayman have? Is this normal and I just need to drive it more? I already have a few hundred miles since last reset and it's driving me crazy that the monitor won't come up. I need to get it smogged Thanks for the help! Mike in San Diego.
