Error Code 89

Hi Guys,
The Cruze 2013 got Error Code 89 after Automatic Transmission System repaired.
I also replaced the Thermostat housing, but the error did not resolve.


The repairer tore off a number of wire cars and did not tell me anything.
So I guess that the Thermostat sensor's cord has been cut off, I searched for a Thermostat sensor wiring system very much, I did not find anything.
Please guide me if you have a wiring diagram of this sensor.


with best Regards
Saeed
