Vehicle make/model chevy chevy suburban
Year = 2003
Mileage = 224000
Engine size = 5.3
dash lights = yes after occurs the problem
codes = CO237
work done prior = transmition rebuilt
work done to repair = neutral safety swich speed sensor all
tech = jk
question = i have code CO237 this codes comes when i am driving arount
30 mph and i go over i bump the brake light abs and rear speed
sensor this has speed sensor on the transfer case you can drive the truck
in the hightway but as soon you go over i bump all this light comes
on any sugyestion i disconect all the spees sensor the abs module the
transmision module i move the pcm to a better place still the problem
there
JK:
There are 2 vehicle speed sensors (vss) on the transfer case. 1 on left, 1 on rt., furhtest to the
rear. Inspect those wires VERY carefully. Also inspect the wires all the way back to the pcm
under the hood. If all look ok, would suggest runnig new wires to both sensors. Have had a
couple trucks with similar concern, the wires test good, pulling on wires does not should a
broken wire, and had to run new wires to repair. Not sure why, but that is what fixed them.
