i did the the check  via the green plug under the dash that checks on the computer activation of devices and the relays and the fans all worked fine. So it seems that it should work but it does not.

 

Is there a way to check the coolant temperature sending unit ...for instance by shorting or opening the the circuit via the plug that connects to it

 

what am I missing

 

I dn't want to buy and go thtough the install hassle for a plug tht has no problems

 

any help

 

 

 

 

See attachments.

 

Go to 2nd page of New Gen FAQ under my name, link for FSM.

 

Coolant temp sensors are not that expensive and in this case I would even grab one from a pick and pull

A scanner with live mode would read temps
