Yaw Rate Sensor Inspection

WARNING: This page is about a different car, the 2007 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Connect the connector.
Turn ignition switch on, verify the voltage between terminals D and ground terminal E under the following conditions.
1. Measure combined sensor voltage under static condition.
  Voltage
  
  2.3-2.7 V

2. Measure voltage at output terminal D and ground terminal E when the combined sensor is rotated left and right.
  CAUTION:
  - Be careful when turning the combined sensor rotation position while it is in a reversed state because the rotation direction and voltage will be reversed.
  Voltage
  
  Right rotation: fluctuation between 2.5-4.62 V
  
  Left rotation: fluctuation between 2.5-0.33 V
