Why does the ABS, Brake and Check Engine Light stay on and Speedometer doesn't register till 25mph

Asked by May 22, 2013 at 01:10 PM about the Dodge Ram 1500

Question type: Maintenance & Repair

The ABS, Brake and Check Engine light all stay on and the speedometer doesn't register
till you get around 25mph and also drops out when approaching a stop. All was fine till I
shifted from 2 wheel to 4 wheel and also fueled up. The check engine code was P0138,
O2 sensor down stream. Any suggestions?
