California smog check failed

[Sean D]

Thank you all for your respnses. I also found some articles on Renntech and I think I've figured it out. Just need to drive the car a couple of weeks as my commuter to reset the OBD II. It was in hibration during the winter (past 4 months) untill I had to smog it for registration.

When trying to get monitors to run, remember that it's how you drive, not how long you drive that matters. Based on my experience with other (non-Porsche) vehicles, the once-per-trip monitors will not run at highway speeds. You could drive at 75 mph from LA to San Francisco and most likely no monitors will run. I don't have the Porsche factory service manuals, so I don't know if those documents even explain the parameters (road speed, load, engine rpm, etc) under which each monitor will run.

I'm a Smog Tech for California.... changing your battery will erase the monitor.... I encounter this all the time.... just drive it a bit and good luck
