My spark goes out

Hi, for a few months and more and more frequently, the Spark 2005 is turned off . This happens when I am going to turn it on, once there is no problem, it also goes out when I am giving reverse. I have been told that it can be a sensor, the Scaner threw a sensor in the acceleration body. I would like someone to tell me if this can be serious and if expensive.

Seriously, expensive yes, new vehicle sensors are a bit expensive, but it only does it in reverse and when you turn it on or during the day too, see if you can give us a little more data because we are short of information.

Thanks for the answer. Look at the symptom is that it goes out at the start or when I reverse. Once in progress it has no problem, that is, I must be to be many times or accelerate Case in immediate synop I want me to go out. What they told me is that the Sacaner throws an error in the acceleration body, but I do not know if it can be a battery or thing. Just go out and I think that is normal.

Normal is not, but if the SCAner tells you a problem in the acceleration body, and your vehicle is equipped with electronic accelerator then it is not much what you can approach, because it also is responsible for regulating on a lower I erase the code see if it appears again, sometimes those codes in memory bother until you take them out and you should not buy anything
