Received the P0411 and p2440 codes when getting a diagnostic.

Question

Can anyone tell me if this is something I could fix on my own and point me in the right direction? I need parts information and "how to" instructions.

Answer 1

P0411 Secondary air injection incorrect flow detected.

P2440 Air switching valve stuck open,

Lets start with P0411,this is about the secondary air pump which the catalytic needs for cold start,for a catalytic to work properly it needs to be at temperature where it can perform its job, P02440 this is a switch when the air injection needs to warm up the catalytic this opens and allow air to flow out,Satify this code first this is the cause of the other code to appear.make sure the air pump hose are disconnected. because it will set off this code a stuck open P2440 will set off P0411. If the air flow hoses are connected ,no breaks,the solution is replace air check valve
