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. -
I recently had to replace the water pump on my 2001 Boxster. This all went fine, however, the red light to the right of the temperature gauge is blinking at 1 Hz. I've read this indicates low coolant level. I followed the factory procedure to bleed the system and it is filled to the max, but the light still blinks. Also, the gauge is flatlined to the left. I replaced the temperature sensor near the #4 cylinder head without improvement, and the wires "look" ok. All the fuses are good. Does anyone know the procedure to troubleshoot this wiring? Or the pin and socket numbers for the wiring diagram? The temperature gauge worked fine before the water pump blew up. I did recover most of the impeller, but a few small pieces are in there.
