yaw sensor/anti block sensor

[ericinboca]

Part number 996.606.145.00 from a 2004 986S with PSM.

When I search online for this part, most places come back calling this part an "anti block sensor for the ABS system." I'm not sure what that is. I think it is the yaw sensor. Maybe that is the same thing as an anti block sensor.

First question -

Anyone know definitively what this part is and how it works (generally)? (For example, if it is the yaw sensor, it measures rotation around an axis, etc., etc.)

It shows on the part that it should be oriented front-to-back, meaning it says on the part which end should be pointing to the front of the vehicle. I believe it was located under the center console just forward of the shifter. I also believe it was mounted level.

Second question -

If mounted level and pointed toward the front correctly, can it be remounted higher? Say six inches higher, and can it move forward in the car about 6 - 8 inches - but still be on the middle tunnel?

The part is most likely an specifically calibrated accelerometer, and where it is located is actually critical as you would like it to be as close to the car’s actual center of gravity as possible, so moving it will have some impact on its level of sensitivity and response time…….

ABS stands for "Anti Blockier System". Basically, your search is giving you a bad translation. The part is a sensor which measures the wheel speed to make sure you aren't locking up your wheels.

Eric,

I believe JFP got it right. It is a sensor for your PSM and the location is important. If you are willing to ditch the PSM system entirely then you can remove it.

Caveat: my car does not have this PSM sensor and I have never removed one but I have seen similar sensors on other German cars. You are on your own as far as procedure or results.
