1997 Buick Park Avenue Ultra 3.8L SC with codes C1234 and c1223

Question

Hi

I get c1234 and c1223 DTC codes. How to check where the electrical wiring has short or how the wiring is routed. If I get little schematic appreciate.

Thanks in advance

Answer 1

C1234  LR wheel speed sensor circuit open or shorted

C1223 LR wheel speed sensor input signal = 0

The OHMs value 850 to 1350. just replace the wheel speed sensor,The wheel speed sensor generates its own voltage,
