i failed my test and was wondering if you can help me. the code p0719 ( torque converter / brake switch b circuit low). do i need to replace the switch ? someone told me that its a power or ground issue, does anyone know what i shoud do to correct this ? also where is the switch located ? thank you for you advice. jim

 

Try adjusting the cruise control release switch as it also controls the TCC.
Top switch on brake pedal.

 

thank you very much pete.
