Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. I will see if I can help you with these fault codes. Lets start with clearing all of them with either your scan tool or by disconnecting the negative battery cable for a few minutes. After they are cleared drive it and lets see which ones reset. Once you have them, post back with them and we can work from there to see if we can determine the cause.
