Hydralulic pump for ABS keeps running after vehicle turned off.

There is a problem in the electrics of the vehicle. First place to start is to check the alternator drive belt for condition and tension. Next place is the battery terminals and condition and tension . Third place is to have a load test done on the battery as it may have an internal short and drawing all the current from the alternator. In effect when you add power requirements ( park lights then brake lights then headlights) you are actually using more current than the alternator can supply to keep the engine system running.

Where is the ABS use on a 2000 Expedition it keeps running while it is off

Safety feature on this vehicle, only way to disable it is to either pull the abs relay out from the fuse block under neith the hood or even pull out the abs fuse, however the abs light will stay illuminated because of this..

I'm probably not going to be able to give you a proper diagnosis without knowing which codes are setting the check engine light. There are about 300 problems that can set the light. Most common thing for your vehicle with not running bad is what they call the DPFE (differential pressure feedback) sensor. It's basically a vacuum/pressure monitor for the EGR system and they get stopped up or corrode as they have exhaust gases running through them and are made from aluminum or plastic. If you post code numbers (go to advance or autozone and they will read them for free) and I can give you a better idea of what the problem is.

Where do u unplug abs module on 2000 ford expedition

abs motor bad or sensor making it run

Sounds like a battery, charging system, serpentine belt slipping problem. Just drive the vehicle to a Auto Zone and have them check the battery and charging system. Please let me know if this helps.

The noise is a clicking noise which means the abs is engaged due to a bad sensor, which runs the battery down after it runs for a while. A shop can read abs codes with a scanner.

abs warning light is on and is also making a continuous sound in the engine and remains on making sound even when car is off. what is this

The brake fluid is on top of the master cylinder in a reservoir. Yes the level being low cause light to come on but so could many other reasons.
