Does anyone have the part number for the SAI valve? I can't seem to find it via a search here, on Robin's DIY site, or on Pelican.

Viper Bob, maybe you can help me answer this question. This is mainly for my 996 as I have the SAI issue which is setting off the CEL.

Sorry I have not been paying attention for the past couple of years.

What exactly sets of the CEL light when a SAI is bad?

Just guessing here, but I imagine when the SAI system is activated (during a cold start), the computer measures the values coming from the O2 sensors and, if too high, i.e., a rich condition, it's assumed the SAI system has failed.

Sound good???

P.S. - Did you get your check valve off???

planeguy: Have you considered adding your great write and pics to the p-car DIY site?

Your pics come in VEY handy when one must remove or replace the air box for the first time. Great job!

The front O2 sensors not reaching a low enough voltage when the air pump is run
during a cold start.
