Transmission Input RPM Sensor
The Transmission Input RPM sensor function is relevant to the RPM of either a Clutch or Torque Converter, depending on if the vehicle is manual and automatic. A Transmission Input RPM Sensors is used to monitor the speed of the clutch (or torque converter), and will signal an alert in the ESP software if the sensor detects an RPM above a predetermined RPM. This helps to reduce damage to the clutch, Torque Converter and drivetrain component caused at high RPM, or to alert the driver if the clutch or torque converter is slipping.

Wiring Tab
Connections
Transmission Input RPM Sensor Input
Select an appropriate input to use for the clutch or Torque Converter RPM sensor. An SPI/DPI (Synchronised/Digital Pulsed Input) should be used.
Connection Type
Edge Select
Select the edge of the signal to be used. Typically this will be Falling unless instructed otherwise.
Sensor Type
Select if the sensor being used is a digital Hall Effect or a reluctor sensor.
Pull Up
Some Hall Effect sensors require a Pull Up if it is not incorporated in the wiring or the sensor itself. Enable as required.
Calibration Tab
Number of Teeth
Indicate in this box the number of teeth per revolution.
Diagnostics Tab
The settings in this tab allow limits to the set for the detection of either fault conditions, or conditions that could be considered to cause engine damage.
Operating Max
When enabled allows detection of Transmission input RPM conditions that could cause concern. When the Transmission Input RPM exceeds this amount it will activate the DTC P1699. If the Engine Protection function is active a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
