Yaw Sensor
Yaw Sensors are used to monitor the twisting or oscillation of a moving vehicle about the vertical axis - or yaw. This function causes an alert or DTC in the ESP software if the yaw sensor exceeds a predetermined maximum or minimum yaw.

Connections
Yaw Input
Select an appropriate input to use for the yaw sensor. An AVI (Analogue Voltage Input) or an SPI (Synchronised Pulsed Input) should be used.
Connection Type
AVI
An AVI (Analogue Voltage Input) is suggested.
Pull up
Enables a 1k pull up resistor to 5V.
Typically the pull up should be enabled with any two-wire temperature sensor, and disabled for sensors with their own voltage supply. If the sensor is being shared with another ECU, such as with a piggyback installation with an OEM ECU, then the other ECU will generally include a necessary pull up and this setting should be set to Disabled.
SPI
An SPI (Synchronised Pulsed Input) can be used where there are no available AVIs.
Sensor Type
Set to Hall Effect for all analogue inputs
Pull up
Enables a weak 10k pull up resistor to 5V.
Typically the pull up should be enabled with any two-wire temperature sensor, and disabled for sensors with their own voltage supply. If the sensor is being shared with another ECU, such as with a piggyback installation with an OEM ECU, then the other ECU will generally include a necessary pull up and this setting should be set to Disabled.
Calibration Tab
This allows calibrations for a Yaw Sensor to be loaded or saved. A number of calibrations come pre-installed with the ESP Software package. If your sensor is not listed, a custom calibration can be created with the data provided by the sensor manufacturer.
From the image above:
1 – Selecting the yellow Open icon on the top left will allow the loading of a pre-configured calibration file.
2 – Selecting the blue Disk icon next to the open icon will allow the saving of your custom calibration file.
Diagnostics Tab
The settings in this tab allow limits to be set for the detection of either fault conditions, or conditions that could be considered to cause engine damage related to the yaw.
Raw Min
When enabled, this allows for the error code C1032 to be set when the voltage is below the set amount. This is used to detect a short or disconnection with the wiring. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
Raw Max
When enabled, this allows for the error code C1033 to be set when the voltage is above the set amount. This is used to detect a short or disconnection with the wiring. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
