Causes

Failed or damaged steering gear (rack & pinion or steering box)
Faulty steering angle or torque sensor(s)
Wiring harness damage, poor connector(s) or corrosion to steering-related circuits
Faulty or miscalibrated steering control module / EPAS ECU
Hydraulic power steering fluid low, contaminated, or pump failure (if applicable)
Mechanical binding, excessive play, or damaged gear teeth in the steering assembly

Symptoms

Steering warning lamp or EPS/Power Steering warning illuminated
Reduced or loss of power steering assist; heavy steering effort at low speed
Intermittent or inconsistent steering effort or steering kickback
ABS/ESP warning or stability control intervention during steering events
Noise from steering gear (grinding, knocking) or excessive play in steering wheel
Possible inability to complete self-calibration of steering sensors

What to check

Read and record freeze-frame and live data from all steering-related modules; note any additional DTCs
Perform a full vehicle scan for related chassis, ABS, and communications (U) codes
Visual inspection of steering rack, boots, and tie-rods for damage, leaks or foreign obstruction
Inspect connectors and wiring at the steering rack, column, torque sensor and steering control module for corrosion, looseness or damage
Check power and ground at the steering control module and related sensors
Verify hydraulic power steering fluid level and condition (if hydraulic system)

Signal parameters

Steering angle sensor output (degrees)
Steering torque sensor output (Nm or voltage)
EPAS motor current draw (A)
Rack position or travel (mm or counts)
CAN bus messages and error counters for steering module
Power supply voltage to steering module (V)

Diagnostic algorithm

Retrieve all stored codes and live data from engine, ABS, EPS/steering module and gateway; record values and freeze frame.
Visually inspect steering rack, column, boots, tie-rod ends, connectors and harness for damage, chafing, or corrosion.
Verify battery voltage and main power/ground to steering control module; check fuses and relays related to EPS.
With ignition on, monitor steering angle and torque sensor outputs while turning wheel slowly; look for dropouts, unrealistic values or mismatch between sensors.
Check continuity and resistance of sensor harnesses (column to module, rack to module); repair any shorts/open circuits.
If hydraulic, measure fluid level/pressure and inspect for leaks; verify pump operation and pressure under load.
If signals and wiring are good, perform module self-tests and request/force diagnostic routines per service manual (relearn/calibration of steering angle sensor, torque sensor calibration).
If a specific component fails tests (sensor, rack, EPAS module), replace only the defective part and follow manufacturer post-repair calibration and bleed procedures.
After repair or replacement, clear codes, perform required calibrations, and road-test to confirm resolution; re-scan for stored or pending codes.
If intermittent or CAN communication faults persist, inspect vehicle network wiring and gateway modules or consult OEM technical bulletins.

Likely causes

Damaged/failed torque/steering angle sensor
Connector/cable chafing at rack or column
Faulty EPAS/steering control module
Mechanical damage or binding in the steering rack

Fault status

⚠️ Status

Steering system gear fault detected. The steering gear or associated sensors/electrical system is reporting abnormal operation. Steering assist and vehicle stability may be affected; inspect steering gear, sensors, wiring and control module.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1-4 hours
