For the first time I got CEL. I have been running the Injen CAI and the Magnaflow CB for about 1-2 months now and I have never got CEL. Just yesterday I got it, so I hooked up the OB2 CodeReader and I got the code P2554. After looking it up on the website, the message was: P2445 Generic Secondary Air Injection System Pump Stuck Off Bank 1 ANDP2445 Toyota Secondary Air Injection System Switching Valve Stuck Closed Bank1for the Toyota one. Does anyone know where this valve is and what maybe caused the problem to show up?ThanksBrian
