Hi all. I know the Secondary Air Injection/0410/1411 problem has been covered here many times over the last 5 years or so, but I haven't found any posters who follow through with the end results. I'm currently having the same problem and am after some advice.
This is going to be a little long-winded, but I'm sure the technically qualified will appreciate the extra details when trying to come up with a solution.
History - I drive a 6 spd '02 Boxster S with 65k miles. About a year ago it started throwing the 0410/1411 codes every month or so, setting the CEL when the engine was cold. I cleaned the MAF sensor with CO2 cleaner and the problem went away. About the the same time I bought an SUV as my daily driver, so the Boxster only did about 8-10k miles in the next 12 months.
The Problem - About a month ago the car started throwing a 0410 code weekly, with a slight decrease in power and fuel economy. Freeze frame data from my Innova 3100a Code Reader was;
Fuel Sys 1 OL-Drive
Fuel Sys 2 OL-Drive
Calc Load (%) 9.80
ECT ('F) 118
STFT B1 (%) -5.47
This morning the CEL was set again, this time the 0410 was accompanied by the 1411 like last year. Over the last few days there has been a significant decrease in power and fuel economy (40m/quarter tank of gas). The following freeze frame data was also captured;
Fuel Sys 1 OL
Fuel Sys 2 OL
Calc Load (%) 15.69
ECT ('F) 118
STFT B1 (%) -6.25
I'm pretty sure the air injection pump is coming on when I first start up (have only checked it once so might be intermittent). I have also cleaned the MAF again (no change this time).
My Dilemma - My SUV is off the road with a cracked radiator and other problems. I can't afford to pull the Boxster apart to fault find it as I need it to get to work every day, plus I have very little spare time right now. I also live more than 2hrs from the nearest dealer and can't afford to have them fix it anyway. It's also due for it's smog/rego this Monday.
What I'm After - Can anyone with real qualifications and/or experience suggest with some confidence which is the most likely component I should look at first, given the limited time I have to spend fault finding and repairing (the air-change valve, electric change-over valve, the line between them or something else)?
What's In It For You? - If someone can nail this problem, I'm willing to offer some sort of remuneration. Depending on your location and amount of help offered, there could be a case/carton of one of the best beers in the world, Australia's James Boags Premium, or for the non-beer drinkers, a bottle of your favorite hard liqour headed your way. If you're not in the CA/NV area, or you're a non-drinker, I'm sure there's a giftcard out there with your name on it.
So, if you think you can help, or require extra info, please post here or email me at
saf_069@hotmail.com. I'm heading to NY for the next 5 days to celebrate (commiserate) my 40th birthday, so might take a day or two to get back to you.
Thanks in advance for any replies.
