ABS and traction lights always on

Hi Angelito,

I assume you are checking your speeds sensors and it is giving you this reading. If that is the case, do you have any DTCs? The fact that the light is on you will have some codes. The fact that you are checking your speed sensors, I assume you have codes for these. I just want to get caught up to where you are.

Let's start with what codes you have because that will help. However, if you measured resistance in the sensor itself (I assume you measured from the connector on the wheel well) then where did you measure your voltage? Same spot?

Let me know and we can go from there. Thanks

Most likely it is a speed sensor but there is one in each wheel so there is no way to know which one it is without those codes. If your scanner doesn't pull those codes it because it only pulls off of the main communication network. You need a scanner that can pull from all networks. If you stop by a parts store with the car, they should be able to pull these codes for you. If your ABS light and traction control light are on then there are codes to go along with it. If you don't have those then you are completely guessing.

I wouldn't recommend replacing anything without pulling those first because what you described about the engine reving up does not point to any issue. In fact, I wouldn't think that is abnormal because when there is no load on the tires, the RPM and speed can race very easily. They have a tendency to act crazy when the tires are off the ground and it is in gear.
