  1. 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 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.
  2. For the 2001 cars there is a very difficult,obscure Secondary Air Injection ( or S.A.I.) "Not Ready" problem. This is also called "Inc" or "Incomplete". JFP has mentioned this in the past and we've had a few sagas here trying to resolve the issue but none as extreme as this one. The car shows no MIL/ Check Engine nor any Pending Codes. You won't fail a Smog Test even in California with this problem - your car will be "Declined". Which is nonsense because you won't get a Pass smog test certificate and you'll be unable to get tags for your car. But do pay the invoice !! You will be told by the smog tech to' just drive the car'. I have been ' just driving' mine for 2400 miles and 20 months. The SAI according to Durametric and Foxwell NT520Pro is still Not Ready or Incomplete. No codes, no pending codes. The S.A.I. system works perfectly by any diagnosis- O2 sensor voltage ahead of Cats at start up(thanks Ahsai). air flow of SAI pump,exhaust posts in head are clean,all SAI hoses and connectors are new/upgraded.Check valve receives strong vacuum while SAI pump operates. All 4 O2 sensors are new but I am open to replacing them all. Which are the fastest responding brands? NTk, Bosch ,Denso ? Using an emulator(for diagnostic purposes only) in the O2 sensor circuit makes no difference. The Referee refuses to test the car insisting it goes to the Porsche dealer for repair. That is a blank check because the Dealer speculates it might need a new ECU ,a new SAI system etc. Really the dealer doesn't want to attempt obscure repairs on an old car. The old techs who understood this problem have retired. The reflash with ROW option is eliminated because the new (DAD) smog machine will detect the abnormal code and your car will fail for 'equipment tampering" One option is to get a reflash to stock ,hoping that there may have been some bug fixes in the latest reflash . Is this reasonable ? The ECU is a 2001 original and unmolested. Another option is to get an Indie with PIWIS to 'force' a Ready status even temporarily and then Smog test immediately. Any recommendations in S.California ? I have done the Drive Cycle many times. What is unclear is how to prompt the SAI to operate during light load/cruise/2900 rpm - if that is even relevant ? I can do that because I have a plugged aux vacuum line via a Tee to the Check valve and a bypass switch to manually operate the SAI pump. This thread may be a good spot to document an effective solution to this problem. It affects very,very few 996 and 986 M96 engines so the usual Internet resources are unhelpful. Any ideas/solutions ? Thanks for any ideas.
  3. Hi all, 2000 Boxster Tiptronic with 113k mi. I recently removed the transmission to deal with another issue, but while doing so some of the brittle SAI hoses cracked and/or became disassembled. I have replaced the cracked lines (i.e. not all of the lines) and reconnected according to the following picture, with the exception that I have a Tiptronic and there is a hose that runs to a changeover valve on the transmission: I get the typical SAI codes, P0410 (80) and P1411 (208), about every 150mi driven. Otherwise the car drives great...SAI pump is running and holding air as usual. Presumably, I have something connected incorrectly, possibly with respect to connection to the transmission changeover valve. The one thing I notice different than before removing the transmission is that the car seems to be running cooler than before. I suspect this could be caused by the changeover valve for the transmission as I think it controls the flow of coolant to the ATF cooler (not sure about this and hoping for clarification). The other thing that I don't really suspect, is that the new hoses used do not have the small bulbed end to help with that snap-fit into the intake sleeves. I have not found a good image showing the SAI hose routing for a 986 Tiptronic, so if anyone knows of one I would be very grateful. I have the Bentley manual which also does not show a Tiptronic-specific diagram for SAI routing. Any other ideas or does this sound like simply incorrect hose connections? Many thanks for your input!
  4. Hey guys, So I'm having this issue that is driving me crazy. My SAI (Secondary AIr Injection) and Oxygen Sensor are not reaching "Ready Status" A little background about my car. 2006 Boxster S 3.2L FVD Exhaust system GMS Headers with 200 cell cats - has all 4 O2 sensors attached. 996 throttle body and distribution hose ECU Tuning Group tune I had the car up in BC Canada since 2009 (although it is a US car) and had no problems passing the sniffer and obdII tests - both before and after all the mods except for the ECU tune. I went to get my emissions testing done last week in Texas and failed due to the 2 systems being in not-ready status. I figured it might have to do with the cat delete (ROW) configured in the tune. I sent my ECU back to ETG in California and had them re-flash my ECU in order to re-enable the O2 sensors. I cleared all codes and figured I would start fresh. I drove the car about 120 miles and attempted to follow the drive cycle mentioned in the forums but it was really tough with the roads out here. Everything is in ready status except for the SAI, and the O2 sensor. I can manually start the SAI using the Durametric system so I would believe the pump is not bad; however, I'm not sure that I"m hearing the SAI start up when I cold start the engine. For testing purposes I unplugged my O2 sensors from both bank1 and bank2 and they both threw fault codes which confirms that the ECU tune re-activated my sensors. I've uploaded a few pictures with the results from a OBDII app as well as the Durametric Software to my Google Drive. I'm not quite sure how to interpret the Durametric Voltage results - especially the negative 50 V and -127V - seems quite odd. https://drive.google.com/open?id=0B4ncE-o5M02DeUlLZVlxRV9hX3c Any help or guidance will be appreciated as I'm out of ideas. Thanks, Joel
