Question Hi, my service engine soon light is on. i did the test and it showed the following error codes: E55 and E85. I cleared all the history and these codes are still there. No other ones. I looked it up and it has smth to do with throttle... I don't know much about cars. Is this smth I can fix myself pretty easy or do I have to take it in somewhere. And if I do, how expensive do you think this repair will be? Thank you very much for you help!
Answer E55 = Throttle position sensor misadjusted.
E85 = Throttle body needs to be serviced.
