This code indicates the ABS or electronic stability control module has detected an abnormal voltage, resistance, or signal pattern from the secondary (redundant) circuit of the steering wheel position sensor. The sensor reports steering wheel angle to enable stability control, traction control, and electric power steering functions; Signal B specifically refers to a redundant channel or secondary data line used for plausibility checks. A fault here typically means an open, short, or performance issue exists in that specific sensor circuit rather than the primary Signal A path.
Internal wear, corrosion, or damaged sensing elements cause the Signal B circuit to read out of range, intermittent, or static, failing the module's rationality checks.
Broken internal ribbon cables or worn contacts within the clockspring disrupt the signal path between the rotating steering wheel sensor and the stationary column harness.
Corroded, backed-out, or moisture-contaminated pins in the steering column connector, or chafed wires in the column harness causing open circuits or shorts to power/ground.
High resistance in the sensor ground circuit due to corrosion at the grounding point or splice pack, causing voltage drop and signal corruption on the B circuit.
Sensor installed physically off-center or not initialized after previous repairs, causing Signal B to disagree with Signal A or expected values during self-tests.
Rare internal fault in the receiving module causing misinterpretation of a valid sensor signal; verify only after confirming correct sensor output and intact wiring.
Generally yes for normal driving, but electronic stability control and possibly traction control will be disabled or limited. This reduces vehicle stability during emergency maneuvers on slippery surfaces, so drive conservatively until repaired.
Often yes. If the steering angle sensor was replaced, removed, or recalibrated, a professional alignment ensures the sensor reads true zero when the wheels are actually straight, preventing false stability control activation or steering pull.
Usually not. Most C0053 faults are caused by the sensor itself, clockspring, or wiring issues. Control module replacement should only be considered after thorough testing confirms the module is receiving correct signals but interpreting them incorrectly.
Clearing the code will likely extinguish the warning light temporarily, but the underlying circuit fault remains. The light will return once the module runs its self-test, usually within a few drive cycles, because the hardware defect persists.
