Bosch combo pressure/temp sensor issue

EMU BLACK / CLASSIC
1

Hey all,

I am having issues with the bosch pressure/temp sensor combo. Have replaced the sensor and i still have the same issues as before. Struggling to calibrate the temp side and also pressure side does not read anything. Have triple checked wiring and it is all correct as per supplied diagram from supplier. Currently have the pressure on AIN5 and temp on AIN6. Sensor is the genuine bosch not a copy.

There has to be something I am doing wrong. Hoping someone here has encountered the same issue as me and can guide us and tell me what they found and how they rectified the issue.

For me is working great this sensor, have installed for many ecus without any issue. Maybe you mirrored the wiring? Check with a tester between pin 3 and pin 4 is there +5v? The diagram must correspond to the connector from wire side!

There is an in-program wizard for the calibrations. You need to activate pull up 4k7 from the analog menu for the temperature reading…Thats it. otherwise sensor is bad or wiring wrong…
