Transmission Input RPM Sensor

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)
