    I read these all the time, hoping you guys can help me-

    I have done no mods to my Tacoma. Driving normal one day. Started up the car, and suddenly got several lights and messages at once- check brake system, pre collision malfunction, abs light, traction light. And just for fun, when I tried the cruise, it malfunctioned. When I read the codes, it told me I had an open circuit with the rear right speed sensor. I replaced the sensor, erased the codes. Then oddly enough, the lights stay off and the speedometer needle and digital speed display bounces up and down 3-5 mph.
    Yesterday I took a speed bump and lights came back on. I checked the new speed sensor. A little bit of grease got on it so I clean it off. The wires all seemed good and connected. I check all the fuses in and out were good.
    Essentially I have warning lights and good speedometer. Or I have no lights and a bouncing speedometer. I’m attaching screen shots of the warning light codes
