I have a 2013 Chevy Equinox 4 cylinders LT, I bought it a while ago. I bought it even though it had the check engine light on, it I didn't care about it. Then, I realized that if the check engine was on it wouldn't remote start. I checked the code and it was a p0411 By definition, the code is letting you know that the ECM has detected incorrect flow in the secondary air injection system. So, I changed the pump but the Check engine came back on. So I took it to the dealer and they told me that the engine that it has is the the correct, meaning that the one it has doesn't have the port where the valve for the air pump is suppose to go. Now I don't know what to do, because the engine is working fine and I don't want to change it. Any ideas of how to erase that code permanently?
