Sent you a PM.

Thanks Paul for the follow-up.

The shop has worked its way through the entire flowchart and all things check out. Unless it's an intermittant electrical issue starting the air pump, it seems the only other thing to do is start replacing parts the computer says are working ok, i.e., the MAF and O2 sensors.

I would try cleaning your MAF first before replacing it. CRC makes a MAF spray cleaner. It's an easy job to do yourself. The MAF is easy to get at right next to your air filter.

Had the same exact codes. 2 cleanings of the MAF made it stop for a little while and then I finally got tired of it and replaced it. Voila. No more CEL.

Have you replaced your gas cap lately?

If for some reason you decide to replace your MAF sensor, send me a pm and I'll share with you my experience with finding one on the cheap .

I had the same problem. The trouble shooting list is quite long for the SAS and I got tired of taking the car back to the shop every time the P0410 and P1411 codes popped up.

My "fix" probably won't work for you in Cali due to more stringent test procedures, but it will work for others who have this problem of CEL with a car that has no other symptoms of poor running:

You can reset the DCM to ROW (rest of world) settings which makes a few changes to the car, one of which is ignoring the SAS system. Your CEL works normally at start-up, but wont throw a code for P0410 or P1411. It also gives you a few more HP and you can start the car in neutral without pushing in the clutch pedal.

I don't know if they plug into your OBD port and read your tune in Cali or not, but no one could visually tell you had this done by looking at your car when it starts and runs.

Assuming the error codes are the same, your issue is centered around the secondary air injection and not the MAF. Sounds like either clogged tubing or a vacuum leak. Keep digging. Changing out unrelated parts might be fun but it won't fix the problem. Whenever I get stumped I always ask "what am I missing". Sticking stubbornly to the process of elimination works.
