ABS sensor failures

Postby force44 » Tue Oct 24, 2017 6:13 pm

A few cars have had ABS sensor failures when the problem has turned out to be damaged wiring.

Diagnostic tools should locate which corner the sensor error is, but don't assume it's the sensor that has failed.

The best way to test is to jumper the pins on the ABS control module plug and test for continuity across the sensor plug at the wheel. This should be a first step before just replacing the sensor.

The pins are different for PSM/non PSM cars and years. If you get no continuity, then look for the damaged wire probably where the loom goes through the inner wing area or the front bulk heads.

In my case we spliced a new wire from the inner wing down to the sensor plug. Once sorted the ABS warning light should clear once you disconnect the battery a not re-appear.

Richard Hamilton - something of a Porsche expert - posted this recently on the BoXa.net forum - though it might be of interest:

I believe the 987 has both a yaw sensor (the above) and a steering angle sensor.
