re ABS sensor problem *******I need Help *******

["Smith, Kirby A" <kirby.a.smith@lmco.com>]

AQUATTRO4U@aol.com complained (message snipped) about recurring ABS
problems.  I had similar problems with my wife's 88 90q, and eventually
found one corner had some teeth missing in the axel part that the sensor
reads.  This can happen from rust, and possibly from jamming them with a
misadjusted sensor.  The best check is with a scope connected to the sensor
output, available on 90qs in the engine compartment and below the rear seat
cushion.  Else, pull the axel and look at it.
