19f fuse!!!!
i have a 2001 ML-320 and the check engine light came on, so i took it to my mechanic and he thinks its the oxygen sensors? So he disconnected the rear 2 oxygen sesors cleared the check engine light and told me to drive it for the day. I did the same process for the front oxygen sensors? He thinks there could be a short in the harness, But the 19f fuse controls the oxygen sensors,fuel tank ventilation and some others..can u guess help crack the case?? the truck runs fine but why is that damn fuse blowing out and should i worry for major problems???
