CEL on. Codes:P0410 & P1411

[Dave928]

it also could be just the vac lines to the combi valve are bad...

So I have had it checked out and they told me that the air pump is bad and cost around $1,200 for this part. Does anyone know where to get one of these cheaper? Also, they said to change the air inject check valve and air pump cut off valve. Anyone have these parts that work and they want to sell or know where to find cheap???

I had my mechanic replace the air pump and my cel problems went away. Light is off. Got the part used at a great price from. Waiting to see if I need the other parts.

My CEL came on yesterday. Does anyone know if it is ok to drive my Boxster with the CEL on, code p1411. I read on here that most people are not to concerned and continue to drive for months till fixing. Will this damage other parts? Is it going to effect gas millage? I have to drive to Nashville, Tn from Bowling Green, Ky today its about 3 hrs round trip. Thanks CP711

It's fine to drive with the CEL (assuming it's not flashing).
The SAI (Secondary Air Injection) system faults can be "ignored" for some time without too much problems (fuel efficiency is a bit reduced).

I fought the same exact thing for about a year and a half.. cleaning MAF, checking vacuum leaks, the whole nine...

just last week, i got tired of the CEL coming on every time I "stepped on it" so I broke down and bought a new MAF before taking it to the show to get smoke tested again...

well.. 400 miles later, still no CEL and cold starts are MUCH better.

it's rare that the air pump itself dies, but I suppose it's possible. the two valves are suspect as well, but if you want an easy DIY and one thing to cross off the list (especially since you stated you had cleaned the MAF, this tells me it's probably dirty/not working), you might just try replacing the MAF sensor.

others will say, "it's not cheap and you're just throwing parts at it", to which I agree with to some extent, but it's nice to "cross it off the list as a possible suspect" and in my case, it solved the problem. 10mins and no more CEL's!

Thank you for the reply, I made the trip everything seemed fine. I have to make the trip again today. CEL is still on. Thanks for the info it is a relief to here it isn't much of an issue.
