C0050 — Right Rear Wheel Speed Sensor Circuit

System: Chassis  |  Type: Generic (OBD-II Standard)  |  Make: Infiniti

About C0050

C0050 is a generic (obd-ii standard) chassis diagnostic trouble code recorded for Infiniti vehicles. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C0050 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

Because C0050 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Anti-lock Braking System (ABS) control module continuously monitors the right rear wheel speed sensor circuit for a valid signal and correct electrical integrity. DTC C0050 is set when the module detects an electrical fault in the right rear wheel speed sensor circuit, such as an open circuit, short to ground, or short to battery, or when the sensor signal is implausible or absent compared to the other wheel speed signals during vehicle operation. This prevents accurate wheel speed calculation and compromises ABS, traction control, and stability control functions.
