Yaw Rate
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
This diagnosis checks the yaw rate sensor in the audio-navigation unit. This device detects when the vehicle turns, and repositions the vehicle position icon on the map screen. For more detailed information, see the yaw rate sensor theory of operation under System Description (see YAW RATE SENSOR ).
- Sensor indicates the voltage output from the yaw rate sensor. It should indicate about 2.300 V-2.700 V when the vehicle is stopped.
- Offset is the reference voltage or standard within the yaw rate sensor. It also should indicate about 2.300 V -2.700 V when the vehicle is stopped.
- A sensor output voltage HIGHER than the Offset voltage indicates that the vehicle is turning to the right.
- A sensor output voltage LOWER than the Offset voltage indicates that the vehicle is turning to the left.
- The yaw rate offset, and sensor should both indicate about 2.300 V-2.700 V when the vehicle is stopped. If either reads below 2.300 V, or above 2.700 V, replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
- The yaw rate offset and sensor should be within +/-0.01 V of each other when the vehicle is stopped. The sensor value should change relative to the offset as the vehicle turns while driving. If not, replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
Example: Vehicle stopped
