I have a 2007 saturn ion2 . i keep getiing po411 engine code, i have replaced the air check valve and the air pump and i am still getting the code. will the engine clear itself , and if so how long will it take? or is there something else i need to do? like disconnect the battery so that the computer will reset or is there a sensor that is faulty?

SOURCE: door wont open

yes this happens from time to time,take it to the dealer,they are a pain the in,,,,,to open even for us techs who have done it before,youre gonna need a new door latch assembly,so make sure they have it in stock cuz once they get that door open there is no way to close it till that part is replaced

SOURCE: 2006 Saturn ION2 won't start. Happens every few

This is a very common problem with the Saturn. It's a bad ignition switch. You need to replace it.

Google on common saturn problems and you'll see that hundred of Saturn owners have had this very problem.

It's really amusing how each dealer prances around it and doesn't tell their customers that it's a common problem. If you bring it to them they will know right away what the problem is but they may pretend not to know right away...EVERY Saturn dealer has fixed this on dozens and dozens of their vehicles...

Testimonial: "thanks"
