2003 Chevy Trailblazer b0237 OBDII code

\015 Just had my codes read and the first one was easy but the second was a new code, B0237, most codes start with a P so this was a bit off for me, what Autozone said was that the Rear Wheel Speed Signal was Erratic. ? Never heard of this\015 Posted / edited by AnonymousUser on : 22-07-2019
