CEL with P2440 Code
CEL with P2440 Code
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.
