My Saturn LW200 (2.2L) 2002 shows a error code P0719, does anyone know the problem and how to fix it?
P0719 is brake switch voltage low, so,the PCM is not detecting any power from the brake light switch when the brakes are off, this seems backwards I know but that is a Saturn for you. So check the switch itself and the harness for broken wires right at the connector cause that is the usual spot they break.
