Why does it need to be fixed? As I understand it this system only works on start-up. If the car is running well otherwise, what harm is being done to the engine? IIRC it is possible to turn off this "feature" by reprogramming the ECU/DME to a Euro Mode as other countries do not monitor this.
I could see if there was some sort of vacuum leak leading to rough running or lean condition, but I feel that I am wasting too much time trying to trouble shoot this code. I want to turn off the monitoring of the Secondary Air Pump and cap the vacuum fitting in the system so there can't be a leak in the future.
My car runes perfect, but I have had the car in the shop 3 times to fix this issue and each time the CEL lights-up after driving the car for 3-4 days. They have checked the hoses and replaced the solenoid but the problem comes back. They have checked and the air pump turns on. Since the CEL does not come on right away, it is hard to trouble shoot and frustrating to have to take the car back after each attempt. Its a pain to drop the car off and arrange a ride back home.
I have asked that when I take the car in for its next oil change that the shop reset the ECU/DME to the EURO NORM 3 setting which is supposed to stop the monitoring of the function of the P0410 & P1411 codes...
