C0055 on Jeep
Rear Wheel Speed Sensor Circuit
C0055 on Jeep vehicles indicates rear wheel speed sensor circuit. Au7o has documented this code across 1 Jeep model — most commonly on Wrangler. This chassis code means the ABS/control module detected a problem with the rear wheel-speed sensor signal circuit. Wheel-speed sensors tell the module how fast each wheel is turning so it can manage anti-lock braking, traction, and stability control; on many GM trucks and SUVs this code points to a single rear/output speed sensor at the transmission or transfer case. A lost or erratic signal typically disables ABS and traction control (warning lights on), affecting braking safety, so it should be addressed promptly. Typical repair costs on Jeep range from $150 to $600, depending on the specific model and root cause.
Common Causes of C0055
- •Faulty rear/vehicle speed sensor
- •Damaged, corroded, or open sensor wiring and connector
- •Debris or damage on the reluctor/tone ring
- •Excessive air gap or sensor mounting issue
- •Poor ground or shorted circuit
- •Faulty ABS/EBCM module (less common)

- Front Wheel Hub/Bearing Assembly Failure (Integrated ABS Sensor) — Grinding & ABS Light2007-2025
Front (and sometimes rear) sealed wheel hub/bearing assemblies are a high-wear item on JK and JL Wranglers, especially on lifted rigs running larger tires that load the bearing harder. As the bearing wears it produces a speed-dependent grinding, rumbling, or humming that changes when turning, and free play can be felt by rocking the tire at the 12-and-6 positions. Because the ABS wheel-speed sensor (tone ring/sensor) is integrated into the hub assembly on these models, a failing hub commonly damages the sensor and triggers ABS and traction-control (ESC) warning lights along with disabled stability control. The common service hub assembly for 2007-2016 5-lug JK with ABS is part 513272 (Mopar/MOOG/Timken/Spicer equivalents); note a JK hub part-number change around 2011, so the correct year-specific part must be used.
