Regenerative Braking Force Sensor Calibration Error
on 2012 Toyota Highlander 3.3L V6 Hybrid · AWD
What this code means
The sensor that measures regenerative braking force has drifted out of calibration.
Symptoms
- Inaccurate energy recovery display
- Inconsistent deceleration in regen mode
- One-pedal driving feels different
- Regen indicator inaccurate
- Uneven braking force
Common causes
- Sensor drift over time
- Sensor exposed to moisture
- Calibration data corrupted
- Temperature sensor error affecting calculation
- Sensor connector issue
Diagnostic steps
- Read regen force sensor raw values
- Perform sensor calibration procedure
- Compare sensor output at zero torque
- Check related temperature sensor readings
- Inspect sensor mounting and connector
Repair notes
Perform regenerative braking sensor calibration procedure per manufacturer instructions. Replace sensor if calibration fails.
