Last time I change my oil I broke the speed sensor. I discovered this because my engine was cutting out we're going in limp mode after 10 miles an hour. I have replaced it twice and it's still in limp mode. I tested the sensor for the manual and it's working. If I unplug the ECU while it's running it does not cut the power at speed. any ideas on something else that could be causing this or a way to reset the ECU?
