Customer Question

Just bought a 2001 Dodge Neon and check engine light coming on. (wasn't on when I test drove it, of course!) got codes P0171 and P1684 when I turned key 3 times
JA: Thanks. Can you give me any more details about your issue?
Customer: runs fine, after a short trip engine smelt hot but temp gauge ok
JA: OK got it. Last thing — Dodge Mechanics generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

Hello, my name is***** usually means the front oxygen sensor has failed and P1684 means battery has been recently disconnected so nothing to worry about. This would be about a $200 repair to have done at a shop. Let me known if you have more questions or if there is anything else I can do to help. Thanks.
