ABS AND BRAKE LIGHT ON

[redcloud]

HI
I HAVE A SITUATION WITH MY TRUCK
ABS AND BRAKE LIGHTS ARE ONE, I ALREADY REPLACE ABS SENSOR AND PIGTAIL.
THE 4 TIRES ARE IN THE CORRECT PSI AND BRAKE FLUID IS FULL.
COULD YOU HELP ME?

The ABS light coming on will set a code.

Your first step is to read the codes.

Check Parking brake switch
If parking brake pedal is down even a little RED Brake light comes on and then ABS light
Pull release handle and lift pedal up with your foot, see if RED light goes off

If not look for the switch, if it or its wire is grounded you get what you have now

Its the white switch in this picture: https://farm4.static.flickr.com/3397/3593897441_bbfa91e6b4.jpg?v=1244094169
Unplugged
But I think that's a 1993 Ranger

Hi
As an update
The ABS and Brake light turn on until I put transmission in R
If I disconnect Master Cylinder, Brake light comes off
Every fuse is working
Emergency Brake is working but light still doesn't come on or off and Is correctly connected it
I check Differential Fluid and its a little low, I will refill it tomorrow

Your speedometer working?

My 97 F250 did this and it was the speed sensor on top of the rear axle. Or is that what youre calling an ABS sensor?
