Hi, if your check engine light is on because of the fault code you will not pass emissions.
how can i fix the problem
A P0410 fault code is a fault in the secondary air injection system. You will need to have the system diagnosed to determine the problem. You could have a faulty air pump or one of the valves in the system could be faulty or it could be as simple as a broken vacuum line.
where should look for the vacuum lines
Click here for a description of how the system operates. It's a pretty complex system. You would just need to remove the engine cover and look under the hood for any broken vacuum lines.
The vacuum lines attach to the shut off valves. Just follow them along and see if any are broken.
If they are all good then you are going to need to have the pump and valves checked.
Let me know if you need anything else.
