2005 Buick Century Help
I have a 2005 Buick Century with the 3.1L V6. I have a BlueDriver scan tool and I am getting the C1234 code when I scan the vehicle. The ABS, Traction Control, and service vehicle dash lights are on. The scan report shows the left rear wheel speed sensor wiring harness replacement as a frequently reported fix. Can anyone give me any more specifics about this code? I'd like to know if it'* the left rear, or another area (RR,LF,RF). Any help would be greatly appreciated. Thanks

Well, I just want to follow up with what I found today. I tackled the ABS problem, starting with the RF wheel speed sensor and wiring harness. I checked the WSS and the resistance was around 970 ohms, within the specs called for. I then spun the wheel and read AC voltage with my meter, Voltage was read and increased as wheel speed increased, so I then proceeded to the wiring harness. I checked continuity from the plug at the WSS to the wiring harness connector at the ABS control. Continuity was good. I then moved to the LR and proceeded to make the same checks. WSS showed no AC voltage when spun and wiring harness continuity checked good. WSS also had no resistance reading with the meter, so, I began the process of removing the hub assembly. Really not a major ordeal. I purchased a new hub assembly with WSS and installed it. I then drove the car about 3 miles and the ABS and Trac Off light was still on. I hooked up my BluDriver OBD II scanner and erased the codes. I then drove the car about another 3 miles and afterwards performed a scan on the car. No dash lights came back on and the scan showed no codes. Maybe (fingers crossed) this fixed the problem. Thanks for all the help.
