Just ran ECU daignosis?? Any answers??
I just ran my car's ECU Diagnosis because my check engine light was on? It just came on today and when I read the diagnosis it said 0304(knock sensor) and 0707(rear heated 02 sensor)??? I don't know really what these do but I was just wonderingdoes this mean that I need to replace them or they just had a fault? I am just confused about where to go from here?
