I'm new to the forum and apparently I'm blocked from uploading pictures until I've participated for a while. I will post the pics referenced below as soon as the system will allow...If this code has appeared on your smart and you live far from your smart center, you can buy the part from them (I paid $42 which included shipping) and install it yourself in less than 5 minutes. If you disconnect the battery for a while the code will reset, or better yet, go to Autozone and have them reset it for free with their code reader. The smart center would not send me the part under warranty (for free) because warranty work must be performed in their service area by one of their service techs...$42 was ok with me because it saved me gas expense and the hassle of taking a day off of work. See attached images of the part and its location in the engine compartment. The part only has two vacuum hoses and an electrical connection...replacement couldn't be easier! Best wishes!
