check engine light comes on for a few seconds and off following a big bump

[wlyh9101]

Driving 60 MPH when we hit a jarring bump with rear wheels and the ck. engine light came on turned off after a few seconds. It happened again with the next trip, same problem. Could we have a loose connection somewhere? any ideas where to start?
