Check engine light is on?
My check engine light has been on since i hit a tree in my truck in January,but it only dented in the passanger front fender between the fender flare and headlight. It crushed what looks to be a vacum or something but the sensor is fine. Im wondering what it is and if it could cause my check engine light on. btw if i take the positve battery cable off it stays off for about a month or so. Any help would be great.
