C0237 GMC -

Question

My 2003 GMC Yukon SLT 4WD is acting weird. i hit a rough patch on the road while driving and the ABS light comes on, audio chimes, and the power door actuators unlock and the immidiately locks the doors there after.

i read my ABS codes and got C0237 erratic rear speed sensor. i measured the resistance of the VSS and got approxi 1.34 Kilo Ohms. what should be the expected resistance value??

replacements are going for 41$ canadian on Amazon.ca. i tempted to just replace the VSS.
