C1234Yaw rate sensor fault

  • Toyota/Lexus code · ABS / stability control
  • Lights a warning lamp
How the car detects it
The sensor that tells the stability control how fast the car is turning gives a faulty signal. A bad yaw rate signal can make VSC brake a wheel when it shouldn't, so it is switched off. While this fault is stored, the skid control unit may switch off VSC (stability control) and traction control, and sometimes ABS; normal braking still works. Drive gently and have it checked.
