<<Left Rear Speed Sensor Issues>>

Lights That Came On In Dash

- traction control
- abs
- parking break

My Left Rear Speed Sensor Was Throwing These Codes

-C0215 Left Rear Wheel Speed Sensor Signal Fault

-U0123 Lost Communication With Yaw Rate Sensor Module

-U0124 Lost Communication With Lateral Acceleration Sensor Module

-So I ordered a new sensor plugged it in and the lights didn't go off. So then I unplugged the battery to reset everything, that didn't work. So then I reset the ECU, that didn't work.

-My mechanic scanned the codes again and he thinks it has something to do with wiring. Or a dirty connection somewhere else.

My Questions Are

- How many ohm's should a good tacoma speed sensor read?
- How many volts should be running through the wire to power the speed senor?
- Where to find a speed sensor wiring diagram? Already tried google images.

 

this might help

 

Thank you this is perfect.

 

Just had this same problem. Got a bunch of snow here and maybe I was losing traction for a long period of time and that screwed something up? It’s also -5° and maybe something’s frozen.

 

I have the same problem. I replaced the wheel bearing and abs sensor. The light stayed on even after I tried to clear it. Tested the work I did with the opposite abs wiring (plugged the right side into the lift sensor)it read the sensor. Bought a new harness for the rear ABS, still saying it’s c0215 code. I’m lost on what to do now
