OBD II Question on Code P0411
P0411
Secondary Air Injection System Incorrect Flow Detected
What is the Secondary Air Injection System? Where do I look to check it out?
I reset the code and it hasn't come on again, but if it does, I want to know
where to start looking. I formerly had an engine with a Pulse Air System
that shot fresh air into the exhaust stream to give the unburned fuel
something to react with in the CAT. Is the Secondary Air Injection System
roughly equivelent?
Thanks,
PS
I also had a P0455, but there is no gas cap on the car so this one is
expected. There's no relation between the Secondary Injection System and the
Evaporative Emission Control System, is there?
