I got a 2000 Chevy blazer I scanned it and got codes c0237,c0236,c0235. It's saying it's the rear speed sensor but I'm having a hard time finding its location, can someone get me a pic of where it is and what you think is wrong with it. Thanks!

 

2WD it is located in the transmission tail shaft housing. 4WD it is located in the transfer case tail shaft housing. Keep in mind that DTC's never tell you that a particular part is bad, they tell you which circuit encountered a malfunction. In your case it could be a poor connection, broken wire, faulty VSS, or a problem with the PCM, EBCM or any of the associated network circuits. Without proper diagnosis, which can be time consuming and expensive, an educated guess would be the VSS is at fault. That's just a guess, and the guessing game can get expensive too

 

Haha I'll look into the wires first then the vss thanks cap!
