Hi all! I haven't posted in a while because my 2001 S80 has been great! Here's my question. Having trouble with the front left speed sensor! This is the third one in there (all used) and it is still acting up! The last one I put in was from an S80 but it was from the right wheel! Is there a difference in sensors from the right to left- back to front! They all look the same! Check engine and ABS lights are on! Almost a pounding-shifting noise when I turn left! If I turn off the DTSC everything functions normally! Suggestions please!

The exciter wheel on the CV shaft might be dirty or missing a tooth.

The wire going back to the ABS module might be corroded or damaged.

The ABS module might be damaged or failing.

A good start would be to have the vehicle scanned with a proper tool for Volvos.
