I am having trouble getting my 2001 Boxster S ready for a smog check in California. The rules have recently changed. Year 2000 and up vehicles are no longer driven on rollers with a sniffer in the tailpipe. The check is solely through interrogation of the EMU via the OBD II port. Also, whereas in the past one test readiness monitor could be not reset and the vehicle be tested and if clean, pass the emissions test, now only the evap readiness can be incomplete - no other. Although my vehicle has never thrown an SAI related code, nor pending code, the Secondary Air monitor will not set to ready. A little history. I initially had an illuminated CEL, the codes showing were P1128 and P1130. I discovered the vacuum hose feeding the SAI valve was pulled out from the port on the right rear intake rubber connector. (Wonder why this did not trigger an SAI code, since the vacuum needed to open the valve was not present). Upon connecting the hose and clearing the codes (I have a Lemur Blue Driver), neither the codes nor pending codes have reappeared after several hundred miles of driving. All of the monitors showed ready soon after restart and a small amount of driving except the catalyst, evap and SAI. After driving the prescribed setting cycle (cold idle, 20-30 mph, 40-60 mph, hot idle in gear) the evap and catalyst monitors showed ready. However, now even after a dozen or more 2 minute, 10 second cold start idles, the SAI test still shows incomplete. Does anyone know what the DME is looking for to set SAI ready? One post I found said 125 Mv or less from the pre-cat 02 sensors after 10 seconds of idle with the air pump on. True? BTW, my air pump is operating on cold start and runs for about one minute and 40 seconds. My cold idle is smooth and about 1k rpm in neutral, 800-900 in drive (tiptronic). Should the initial 2 minute, 10 second cold star idle be done in neutral or drive? (I’ve done both) Any suggestions? I’ve talked to the California Air Resources Board, and it appears the referee path is no longer an option.
