Use a digital multimeter to check resistance. Typical Nissan wheel speed sensors read between .
Unlike traditional engine-related codes (P0300 for misfire or P0420 for catalyst efficiency), belongs to the Network Communication family. Specifically, it translates to "Vehicle Speed Sensor – Invalid Data via CAN (Controller Area Network) Bus." nissan dtc u125c
To understand U125C, you must understand the CAN bus. Modern Nissans are not wired with individual analog wires for every sensor. Instead, modules (ABS, ECM, TCM, BCM, etc.) talk to each other over two twisted wires (CAN High and CAN Low).

is rarely a death sentence for your vehicle. While the code points to "invalid vehicle speed data," the problem is almost always a wiring fault, a corroded connector, a weak battery, or an internal ABS module failure. Specifically, it translates to "Vehicle Speed Sensor –
DTC in Nissan vehicles indicates a "Lost Communication with Telematics Control Unit" (TCU).

Try a battery reset by disconnecting the negative terminal for 15 minutes to force the modules to reboot.
