If you did clear code, check for corrosion inside the connector. If that's not it, look for broken wires. Sometimes a wire can get yanked hard enough to break it inside the insulation and you can't see it. The only way to find it is by checking continuity with an ohmeter. You can push sewing pins through the wire at each end to attach the leads.
