Selespeed ECU gives P1750
i m new here but anyway, i have a problem with my AR 156 2.0 TS Selespeed (2001).
Three weeks ago i drove a "crazy" street. At the end of this street, i suddenly could only use N and R.
After driving home in R ;o), i try to repair.
Some selespeed profis (especially Belli) gave me advise so i replaced a sensor and checked the ECU for Selespeed via FiatECUScan; but Error P1750 appears. I replaced the sensor again with a second new sensor but nothing changed.
I checked the System-Connector (20 Pin) via Ohm-device but all seemed to be ok.
I checked the connector to the ECU, but i believe i havent the right pin-out.
I checked the Selespee oil and gave additionally oil into the system.
I filled the battery over night.
After each step i checked the function, but always i got the Error P1750. Sometimes if i tried to switch to 1 some Error like P1746 appears.
Question: Does anybody have knowledgge about my problem?
Thank you in advance.
Btw. i apologize for my broken english.
