Incorrect Temperature Readings from Bosch Oil Pressure/Temp Combo Sensor (0261230340) on EMU Black

[TFSI_a3]

Hi everyone,

I’m using a Bosch oil pressure and temperature combo sensor (part number 0261230340) with my ECUMaster EMU Black.

The oil pressure sensor is connected to Analog input 5 and configured using the Sensor Wizard – it works perfectly and matches the readings from an analog gauge.

The temperature sensor is connected to Analog input 4, but I’m getting either no readings or completely incorrect values when using the default settings provided by the Sensor Wizard.

Has anyone successfully used this sensor on the EMU Black and could share the correct calibration parameters or voltage curve for the temperature input?

Any help would be greatly appreciated!

Make sure correct pullup is selected on wizard

The Pullup in the wizard is 2200Ohm @Greg

Download the manual for the bosch dual sensor and follow the instructions,
with 330ohm pullup accuraricy is best in the temp range where you need it , also dont forget to change pullup value to 330 ohm in the wizard
