Yaw Rate Sensor Bias/Offset
on 2014 Toyota 4Runner 4.0L V6 · 4WD
What this code means
The yaw rate sensor zero-point offset has drifted beyond acceptable limits.
Symptoms
- Stability control light on
- ESC activates unnecessarily
- Vehicle pulls to one side during ESC event
- ESC disabled warning
Common causes
- Sensor internal calibration drift
- Sensor mounting misaligned
- Aftermarket suspension modification affecting sensor plane
- Temperature-related sensor drift
Diagnostic steps
- Check yaw rate sensor output at standstill (should read zero)
- Perform yaw rate sensor calibration
- Verify sensor is mounted level and secure
- Check for aftermarket suspension modifications
- Inspect for related lateral acceleration sensor codes
Repair notes
Recalibrate yaw rate sensor. If bias returns, replace sensor assembly.
