Location of ABS wheel sensor 96 Astro Dayvan 2WD

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.

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.

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.

ATI LOCK LIGHT ON BRAKES WORKING BUT DONT FEEL THE SAME AS NORMAL


Check Brake fluid level.

When the ABS light is on, the brakes should revert to standard braking.

The only time ABS should invoke is when the tires are slipping as sensed by the wheel speed sensors when the wheel locks up on any of the axles.

ANTI-LOCK BRAKE SYSTEMS General Information Fig. 1: RWAL brake system diagram
Fig. 2:4WAL Component locations — except 1996 models

Fig. 5: Four sensor 4WAL brake system diagram — Except 1996 models
There are two basic types of anti-lock systems available for this vehicle; a Rear Wheel Anti-Lock (RWAL) brake system and 4 Wheel Anti-Lock (4WAL) brake system. The 4WAL system has two variations; a 3 sensor system and a 4 sensor system. The 2WD vehicles will be equipped with the 3 sensor system, but the AWD vehicles can be equipped with either. The systems are easily identified by looking at the rear wheels for a sensor harness. If there is a sensor harness and thus, rear wheel sensors, it is the 4 sensor system. If the vehicle is not equipped with a harness, it is the 3 sensor system. The 4 sensor system takes it speed references from each of the wheels. The 3 sensor system takes its speed references from each of the front wheels and the vehicle speed sensor located in the transmission (2WD) or the transfer case (AWD). The RWAL system components consist of the Vehicle Speed Sensor (VSS), the Electronic Control Unit (ECU), the isolation/dump valve and the Vehicle Speed Sensor Buffer (also known as the Digital Ratio Adapter). The ECU also receives signals from various brake switches. The 4WAL system components consist of the Electro-Hydraulic Control Unit (ECHU) valve (also known as the Brake Pressure Modulator Valve or BPMV), the wheel speed sensors, Vehicle Speed Sensor (VSS) on 3 sensor systems and the VSS Buffer. prev.gif next.gif

They are not the sensors you want. The car uses the abs wheel sensors for vehicle speed. Your problem lies in the abs system , possibly the left front sensor, abs ecu or speedo cluster, Clear the code and see if it stay out otherwise you'll need to go to a trusted technician. .
