Gearbox Torque Converter Pressure Sensor

Gearbox Torque Converter Pressure Sensor

The Gearbox Torque Converter Pressure Sensor is used to monitor the fluid pressure within the torque converter.

Connections

Gearbox Torque Converter Pressure Input

Select an appropriate input to use for the Gearbox Torque Converter Pressure sensor. An AVI (Analogue Voltage Input) or an SPI (Synchronised Pulsed Input) must 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 Gearbox Torque Converter Pressure 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. The default calibration will be for the Haltech 150psi Pressure Sensor.

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.

Display Tab

Warning Minimum

When the Gearbox Torque Converter Pressure reads below this amount, any Gearbox Torque Converter pressure items on the ESP software will flash Red as a warning of low Gearbox Torque Converter pressure.

Warning Maximum

When the Gearbox Torque Converter Pressure reads above this amount, any Gearbox Torque Converter pressure items on the ESP software will flash Red as a warning of high Gearbox Torque Converter pressure.

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 Gearbox Torque Converter Pressure Sensor.

Raw Min

When enabled, this allows for the error code P0847 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 P0848 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)

Operating Min

When enabled, this allows for the error code P0846 to be set when the Gearbox Torque Converter Pressure is below the set amount. If the Engine Protection function is active, a DTC Severity level can be selected for this condition if desired. (Default = Disabled)

Operating Max

When enabled, this allows for the error code P0849 to be set when the Gearbox Torque Converter Pressure is above the set amount. If the Engine Protection function is active, a DTC Severity level can be selected for this condition if desired. (Default = Disabled)
