So my ABS and Traction control light came on pulled the code it says B1227 left rear excess wheel speed variation? So would this just be a bad speed sensor? Little confused because when I did my own research it said it was it was a fuel temp sensor #2 circuit open any suggestions?
The car does nor have a fuel temperature sensor and even if it did, it has nothing to do with the EBTCM.
C1227 - Left Rear Excessive Wheel Speed Variation
That generally means the wheel hub must be replaced, but first you make sure the connector to the left rear wheel is properly connected, clean and dry.
So I pulled my codes same as before so I pulled the tire off disconnected the cable and cleaned the connections and plugged it back up. No luck any idea where I go from here? If its telling me (left wheel speed variation) do I just go ahead and replace the bearing? The cable? Or both? I want to take the next step just need a push in the right direction.
