Had an intermittent stabilitrac message and ABS light for quite some time,until it finally was always there. No drive issues. A friend has HP Tuner program so we hooked up and gathered the stock Programming and ERROR code. C0045, left rear wheel speed sensor.
Ordered an AC Delco unit from Rockauto and installed.
Fixed. No light or error messages

Might be worth checking your grounds and the purple wire running to your gas pedal. A few years ago I had the same issue and it went into limp mode every so often. Showed up as wheel speed sensor but turns out that wasn’t the issue. One of the grounds in the back needed cleaning, the passenger side pillar ground was “meh...ok”, but I cleaned it anyways and adjusted the harness hack job running to the pedal. Been right as rain ever since.
