Causes

Open, short, or high-resistance in torque sensor signal, reference, or ground circuit
Failed or degraded steering torque sensor (internal fault)
Damaged or contaminated connector or wiring in the steering column/clock spring area
Poor module power or ground (steering control/BCM/ABS/ESP control module)
Clock spring or slip ring wear/restriction affecting signal
Incorrect sensor calibration, software or ECU fault

Symptoms

Stability/ESP or steering warning lamp illuminated
Reduced or inconsistent power steering assist (EPS assist changes or hesitates)
Steering wheel feels heavy, inconsistent or erratic
Fault code stored (C0461) and possible related codes
Possible entry into reduced-assist (limp) mode for steering or traction systems

What to check

Retrieve trouble codes and freeze-frame data with a scan tool; record live torque sensor data while stationary and during low-speed steering
Visually inspect wiring and connectors at the torque sensor, clock spring, and steering control module for damage, corrosion or looseness
Check battery voltage and ground integrity before and during testing
Wiggle harness and clock spring with ignition on while monitoring live data to reproduce the fault
Confirm no recent collision/airbag deployment repairs or aftermarket installations that could affect steering wiring

Signal parameters

Reference supply: typically a stable 5 V reference (check vehicle spec)
Signal output: typically centered near mid-supply (≈2.5 V) with small deviation when torque applied; many systems expect ~2.5 V ±0.5 V at rest
Signal range under torque: varies by design (often within ~0.5–4.5 V depending on direction and magnitude)
Ground: near 0 V; low resistance path to chassis ground
Continuity: sensor signal and reference continuity to steering control module with low resistance; no intermittent opens

Diagnostic algorithm

Read and record all stored and pending codes and freeze-frame data. Note any network communication codes.
Confirm vehicle in a safe, stationary condition (wheels chocked, steering centered). Use correct procedures when working near airbags—disconnect battery and wait per manufacturer if required for connector work.
Clear the code, then, with a scan tool, monitor live torque sensor output and reference voltage with ignition ON (engine off). Observe steady reference (~5 V) and signal near mid-rail (≈2.5 V).
Perform a wiggle test: gently move the steering wheel/column and harness while watching live data for intermittent changes or loss of signal. Inspect connectors for intermittent contact.
Inspect wiring from torque sensor through clock spring to steering module for chafing, pinching or corrosion. Repair any damaged wiring or connectors; measure continuity to the module.
Measure resistance or bridge integrity if the sensor is a strain-gauge type (follow vehicle-specific service manual values). Replace sensor if out of specification.
If wiring and sensor check OK but signal level is offset or noisy, check module power and ground circuits and measure for voltage drop under load.
If harness, power and grounds are good but the signal remains out of range, replace the torque sensor or clock spring assembly as required.
After repairs or replacement, perform any required steering sensor calibrations/learn procedures with a scan tool (steering angle/torque sensor zeroing) and road-test to verify.
If fault persists after sensor and wiring replacement, consider steering/ABS/ESP control module internal fault and follow manufacturer procedures for module testing or replacement.

Likely causes

Broken wire or pinched harness in steering column (common at steering column swivel/clock spring)
Corroded or loose connector at torque sensor or steering control module
Defective torque sensor assembly (strain gauge/bridge failure)
Damaged clock spring assembly causing intermittent contact
Blown fuse or poor battery/ignition reference voltage to sensor
Faulty body/steering control module or internal input amplifier
