I have a 2002 ford RangerXLT extended cab fleet side 3.0 When i really step on the gas hard the ABS light comes on I replaced the Break booster pressure sensor and both front wheel sensors and the rear wheel sensor on the diff. and the light still comes on when i step hard on the gas hard. i dont what else to do can anyone help me?

 

Welcome to the forum

2002 should have 4 wheel ABS but only 3 speed/rpm sensors

I assume you are not getting rear wheel to spin, losing traction, under hard acceleration

You replace the fluid level sensor on the brake master cylinder?
Booster has no pressure sensor

Key off
Unplug the 4WABS module in engine bay drivers side
Then plug it back in, that will clean all the contacts
See if issue goes away, free but a longshot

Does the Red brake light on the dash work?
i.e. when you press Park brake pedal down does it come on with key on?
It should, and go off when pedal is released

Red brake light will also come on when Master brake cylinder sensor shows low fluid, and that will also cause yellow ABS light to come on, so both should light up, but if Red light is burned out......................only yellow light comes on

Specific issue doesn't ring any bells
Intermittent ABS light can be troublesome to diagnose
You can check if there are any C codes, those are ABS codes
P codes are engine and transmission
B codes are body, usually cab electrics
C codes are chassis, brakes mostly
U codes are data, module inter-connection issues

 

The break fluid level is full and the sensor i first replaced is in the break master cylinder

 

I have the same issue, and any time the code has come up, it says something to the effect of "brake pressure switch fault"

But it's only intermittent, and it only happens below 30mph, in 1st or 2nd.
