check engine light on with Code P1157

My cousin's 2003 Accord ran over a bump a little bit too fast and 20 minutes later he got a check engine light on with Code P1157. My first reaction is to check if the connection to the O2 sensor is loose from hitting the bump, anyone know where is the upstream sensor? Thanks
