ABS light on after new struts, tires, alignment - HELPt

After installing new struts and tie rods my ABS and ESP light stay on constantly

VCDS reading codes 00283 front left, 003 mechanical failure


I checked the sensor by reading the OHMS and it showed it was still good condition so i dont think the sensor randomly went out...


I am going to try to take from the passenger sensor and plug in to the driver to see if it fixes it at all; any other ideas why this happened?

The sensors are right and left specific. The wiring may have been damaged during installation of the struts.

In vcds you can see the actual speed that the sensors are showing. I forget which module it is but you should be able to find it if you are reading the abs codes.

I have broken several ABS sensors while doing struts, calipers, etc. Easy replacement

how do i know the sensor itself is bad? It keeps showing me that the driver side is bad but it looks great and i tested the OHMS and it reads intact

Since the code is for an electrical fault, I assume it comes back immediately when cleared, as opposed to only coming back after driving the car. In that case clear the code and replace the sensor with a 1.2k resistor. If the code comes back, wiring is faulty. If it does not, sensor is faulty.

it will stay cleared until i drive the car and make the ESP activate or ABS triggered; then i need to clear it again for it to not constantly stay on

do i need to get an OEM sensor?

These two statements are inconsistent. Something else is going on.

I suggest following the steps here (posted by one of our trusted vendors):
