Hi All!
I have a '84 Cadillac Fleetwood. It has trouble code 15. "Open Coolant Temperature Sensor circuit". The BCM test 0.4 show -38 celsius for the coolant temp.
Is it possible the car hitch during driving because of the CTS? The choke is working always. Off course the a car "think" is it cold. I stop the engine when it is warm, the restart is very difficult... Is it depends on the CTS???
Thanks! Sands
