I've had several years of trouble free driving but the other day my CEL came on, the 1st time since it came and went when I installed the CAI about 3 yrs ago. I just got back from Autozone where they read the code. It came back with P2440 which is defined as:Secondary Air Injection System Switching Valve Stuck Open Bank1 and has 4 probable causes:1 - Open or short circuit condition2 - Failed VSV3 - Failed pressure sensor4 - Failed air switching valve I think I have #4, but I don't know how "serious" this is. The car seems to run fine and I don't notice any performance differences. Still, this light is irritating and I want to get it fixed. Anyone have any idea what I can do to fix this?Thanks in advance.
