ABS toubleshooting/help

[rustydawg]

Hello.

A couple of friends and I are trying to track down and repair an ABS fault. I replaced the front sensors and received the ABS light. The car is a 2/89 build date.

This is what we did:

* Removed the ABS computer.

* Measured resistance of each sensor at the computer connector - all 4 sensors returned a value of 1000 ohms. Which indicated a good connection to the computer.

* While driving,without the computer, took a voltage reading from each sensor at the computer connector, 3 sensors read 2 to 2.3 volts - the right front sensor read zero. (Pins 11/21).

* Took another reading at the computer connector of the right front sensor and it is still reading 1000 ohms.

* Verified that the exciter ring and sensor were correctly installed.

Any ideas are appreciated.

A speed sensor, like a crank position sensor, can ohm out okay, but not work. To start with replace the right front sensor.

Delete the ABS, it is a crap system

Delete the ABS, it is a crap system

Well, actually it isn't. On a street car having a working ABS can, in the right circumstances, be the difference in driving the car home with little or no damage or watching it head for a salvage yard on the back of a flat bed. On track it can be the difference between flat spotting a set of tires or meeting a wall.
