I'm receiving error code P0410. I check all of the fuses connected with this circuit but am not sure how to tell if a relay is bad or if it is the pump itself. I reset the service engine light and that seemed to work for about a day and then it came back on again. Where should I start in fixing this problem and where can I get a schematic of the entire system so I know I am checking it all.

thank you

Start by checking related fuses. after that use a scan tool and kick the air pump on. air pump and its relay are located on driver side frame rail below drivers door. if that option is not available on your scan tool then ground the brown wire on the air pump relay and turn key on. this will turn pump on if the relay is working and pump is working. once the air pump is on open up the air solenoid. you should hear difference in sound of the pump. if valve is not opening try tapping on it when you command it open. if scan tool can't do this either than jump the relay in under hood fuse box. before removing valve verify that yo u have power and ground when you are commanding the air solenoid open. the supply pipe from the air pump to the valve may be full of water. if it is then make sure you blow out the lines before replacing any parts.


If you still need further assistance just let me know.
