C1515Torque sensor zero point not set
- Toyota/Lexus code · Power steering
- Lights a warning lamp
- How the car detects it
- The torque sensor has no zero point stored. This is expected after the EPS unit or the steering column was replaced; a workshop sets it with a scan tool, with the wheels straight and the steering wheel untouched. When the power steering limits or stops its assistance, the steering becomes heavy but still works mechanically.
- What you may notice
