Im having trouble with my 940 not starting when its cold. Its giving me the 1-2-3 code for false ect sensor or connection. I have changed the sensor and tried to look at every connection but im running out of knowledge and ideas on what it could be. Does anyone have anyidea on what it could be?

I figured out that theres no continuity to ECM from the ECT. I checked EZK and it had continuity to pin 2 as it should but the other pin of the ECT had continuity with pin 1 of EZK. Im wondering what pin 1 is supposed to be and where there could be a problem in the wires?

 

Also i tried clearing the codes on the obd and for ecu i was able to do it but for ezk i cant clear them at all
