I have some problrem on my2002 S2000!
my car is only 2300 miles, engine light on code P0411, bring back to dealer, come back, engine light on again. I am so unhappy!
Please help THX!!!1

 

Did the dealership tell you what the Code P0411 meant? If the check engine light is on again, it's time to take the car back to the dealer. Does your receipt/invoice tell you what the P0411 means? Did they at least tell you what they did to "fix" the problem?

 

It's no big thing... just an emissions system that is not functioning right. This should not affect how the engine runs, just how long it takes the Catalytic Converter to heat up.

The OBD II codes are common for all cars, I believe. So you can check this link:

Funny thing you mention that code. I just got back from the dealership and they fixed a small leak in one of my vacuum tubes (wasnt on tight enough). P0411. Hopefully that solves my problem.

Talking to the tech he told me that it really nothing to worry about, just that my intake had to build up more pressure inorder to get the right vacuum pressure in the engine. (hissing sound from air stenoid valve)

P0411 can also be other problems too. He told me with a CAI the engine light may just come on also. Hopefully youre still covered under warranty, my bill came out to 74.80. (Thank god Im still within my warranty)

 

Thank you very much!
The dealership call me about car problem. They find out one "electronic control valve" is not working. I hope that will be it!!

But I have a problem! The first time I have this engine light come on is after I drove in the rainly day. I go back to dealership, they reset the computer and told me is ok. The same day after a car wash the engine light comes on again, that make me think that, can I drive in the rainly day or car wash!!

 

Man your S is a tough one. Do you have a CAI? Hopefully its that controller that screwing things up. Good luck...

 

I just pick up my car from dealership, the car seems ok now. But I did not try the car wash yet, hope is ok!!

Hey ytyper is your problem solved? I have been to and from the dealership 7 times and they are trying to track down a similar problem on my car. I am getting the same code. P0411 my car is 100% stock no intake, they have replaced the air control valve and ecu and it always comes on about 2 days after I get it back from the dealer.
