No public code list, bulletin or service manual assigns C0825, so its use by any carmaker cannot be shown. The title points at the torque sensor of electric power steering: a torsion bar in the column or pinion twists under the driver's hand force, and Hall elements read that twist as a torque value. A range or performance fault means the reading stays inside its electrical limits but does not make sense, for example when the main and backup channels disagree. A Mitsubishi Electric patent checks both channels against a torque estimated from the motor current and stops assistance when none of them agree. Makers that publish torque sensor faults use their own numbers, e.g. Honda C1423-14 for the sensor supply on the 2022 CR-V. Expect an EPS warning and heavier steering.

Likely causes

Torque sensor channel drifting or reading implausibly against the second channel
Unstable sensor supply or internal short in the sensor (as in Honda bulletin 22-011)
Poor contact at the sensor or steering module connector

Symptoms

  • Power steering warning lamp or message
  • Steering assist reduced or switched off, wheel feels heavy
  • Uneven assistance between left and right turns
