Can anyone tell me where the ABS sensors are located ? The Haynes tech manual says they are in the transmission extension housing but I don't see them. Also are there sensors on the front wheels?
My problem is ABS light stays on but on rough terrain it goes off until I hit water then on it comes again, otherwise the van drives perfect.
Re: Location of ABS wheel sensor 96 Astro Dayvan 2WD
Most sensors are located at the wheel hub, you should see the reluctor gear mounted on the drive axles in the front, you may need to remove the wheel and rotor to get to it! is it all wheel drive or just front wheel drive, if front wheel drive you should follow the wire that goes to each wheel in the rear, if all wheel drive it may only have one sensor in the transphercase to monitor driveline speed. you really should have some one scan the abs and find out the code/s and diagnose it, just cuase the light comes on doesent mean its the wheel speed sensor, it could be the abs module ect ect..., check the fluid level and make shure its not low and or dirty.

There is an ABS wheel speed sensor located in the rear differential.
If this fails it affects the ABS and may cause your speedometer to read erroneously at speeds under 25-30 mph. There is also a VSS located in automatic transmission housing. Manual trans vehicles don't have this. They use engine rpm to determine speed as there is supposedly no slippage in the manual drive train.
Hello Keith ! Since you are using Haynes Manual Book and you can not locate the component you are looking for, I do not know whether anyone can help you having the autodata program just getting in the system putting the vehicle details and go to components location and surely you will locate it. I believe the speed sensor should be on the automatic transmission.
It could be one of two things. Either a loose/faulty speed sensor on one of the wheels or the ABS module itself. I would check/clean the connectors for the speed sensors first and if that doesnt work then head to a wrecking yard and grab a "new" ABS module.
If located and constructed like most; you can locate it by watching the accelerator linkage while someone slowly and methodically (don't pump) the gas pedal.The throttle position sensor is normally enclose in a round dome-like housing located off the end of a shaft that is part of the linkage. They often have three screws and are mounted to allow some rotary adjustment. There is also normally a voltage to be measured when replacing this to establish the range of the control which is a rotary resistor. Despite some criticisms of Haynes service manuals, I will continue to suggest buying them as I have rebuilt engines, transmissions and found electrical problems using them and I am NOT a professional mechanic. Look at Haynes.com to find if they offer a manual for your car; they cost ~$25.
Ther are more than one type of speed sensor for jeeps....I am chrysler jeep tech...there are 2 speed sensors on the trans and also speed sensors at the wheels (IF IT HAS ABS)...Normally the engine speed is done by an IAC Motor...If you are meaning idle...Can you send more information....
Also you may have a vacum leak..........You have an Input speed sensor and an output speed sensor ....Do you know exactly which it is ....Both are at transmission /If 4 wheel drive see transfer case also.I have the manual at my fingertips and will be glad to assist you with any problems............................I can help................metalpoet
