      You don’t have to. I did because I was I was too cheap to fix it properly at the time. No ABS was far safer than unwanted activation. Sometimes, there is a bit of rust scale that builds up and lifts the sensor (rust jacking), changing the air gap and making the signal weaker and less reliable. Other times, the wheel hub begins to wear internally and can cover the sensor with metal filings, making the signal weaker. The sensors themselves can also go bad.  If your scanner is Bidirectional, then the odds of it being able to read ABS data is pretty good.

      Ah dang, so you just run without ABS then? My scanner is bi directional so I am going to try and drive it later maybe pin point a bad wheel speed sensor

      I seem to recall my Regal doing that as well sometimes. I always attributed it to a delay between an increased electrical demand and the PCM increasing the duty cycle of the alternator to compensate. If your scanner can read ABS codes, you should be able to monitor individual wheel speeds. If it's just a generic OBD2 scanner, those usually can't read ABS data.  That's how mine started.  The odd random ABS pulse, or the occasional ABS light coming on that would disappear after a restart.  Eventually, I had to pull the fuse because the ABS began activating randomly at lower speeds and made things dangerous.

      Also just remembered when I first picked the car up one morning the ABS light did come on. All I did was shut the car off and it went away. Definitely think youre onto something now
