2000 Ford Windstar abs

Yes you can read and clear code for your abs with a scan tool. However you need a get one that will do it. Not all scanners will. So talk to you parts pro at you local parts store and let them know what you need the scanner to do. As for the wheel speed sensors I will have to look in my books at home and find out so I will get back to you.

I asked if THERE IS A WAY WITHOUT USING A SCANNER TO CHECK AND CLEAR THE ABS CODES???????????? like jumping the wires?

In short no there is no other way on an OBD II computer system. Sorry you will need a scanner or have a shop scan it.

how to check wheel sensors using a ohm/volt meter? I asked last week you never replied

I am trying to find the answer for you on this one. I have many books to look through and mitchel 1 (which costs me money) to look at and sometimes it just takes a bit of digging. I have not forgot you so don't worry just need a bit more time.

ok

Ok now the speed sensors generate an electromagnetic field so with the sensor ring which interrupts the the field as each wheel turns it will generate a low voltage analog (continuous) signal. This signal rises and falls in proportion to the wheel rotation speed. So if you where to back probe the wire that sends the signal (which I do not have any information on the wire colors anywhere that I can find looked) and turned on the key engine off and spun the wheel then the sensor would increase voltage the faster the wheel spun and less the slower it spun. I hope this answers you question if you need anything else just ask ok.

Yes you can check your wheel sensors with a ohm meter.. Unplug from the harness near each wheel put a probe on each prong. They should read around 200 ohms if they are good

Hi, a few questions of clarification:

Bad74Charger mentions that a "good" sensor will read around 200 ohms if good.

I'm trying to figure out the "active" test for the sensor would look. Are these sensors:

* Producing "open/short" pulses based on the rotation of the notched wheel, tested by a frequency meter (or OHM meter on notch & out of notch), or

* Producing DC voltage based on variable reluctance, tested with a DC volt meter where the DC volts will change depending on speed, or

* Providing resistance based on the notched wheel, tested with a ohm meter where the resistance will change as the wheel spins different speeds, or

* Something else entirely?

Thanks,
