new coolant sensor not working ign. test pin3 2 vlts in pin 4 2 vlts out? I know I need 5 vlts.what regulates the 5 vlt delivery is it the ECM? I have checked every fuse relay re doing connections ect.. Thank you!
What is your question?
My temp sensor problem started when the connector broke from being brittle lcan you please verify the pin wire location. I haved pin 1=brown&yellow pin2=brown&white pin3red&grey pin4=brown&blue. I have 2 volts in on pin 1 2 volts out on pin 4 so i'm guessing pin 1&2 from ECM & pin 2&4`````to gauge? the connector was mis wired first would that fry the gauge or ECM?
