Hi everyone! I just bought my first s2000 two days ago. It's a 2005 Rio Yellow Pearl in excellent condition. The car came with a check engine light and the code is P0411. After doing a lot of research (especially on this article https://www.s2ki.com/forums/s2000-un...e-help-818975/), I see that it is with the secondary air injection system. The car does NOT have a catalytic converter and instead has a berk test pipe. I believe the secondary O2 sensor is gone too. Could this be the culprit of the code? I need to pass emissions before I put the car away for the winter. Thanks!

 

My friend had this code. One of the vacuum hoses behind/under his intake was loose/kinked. He corrected it and the code went away.
