Had a bunch of maintenance and repairs done on 2002 Dakota SLT Quad cab with 4.7 engine. New fuel pump solved p0300, 0301 and 0302 codes. Brake fluid replaced and brakes bled trans fluid/filter, transfer case and differential fluid, coolant flush and fill, PCV valve. Brakes feel great, but now abs light and brake warning lights come on occasionally and don't return for a while. Never happened before. Could the mechanic accidentally knocked off or damaged a sensor somewhere? Brake fluid is full. Any ideas?

there is a speed sensor in the rear end that probably needs to be replaced. I had the same problem as you and bought one but i flushed my brake fluid 1st and the light never came back on.
