$8B Temp Sensor issue 2.3l HO Quad-4

I will try to find the deffinition but do u think code 15 coolant low is a low coolant level instead of low coolant temp? I do not have a coolant level sensor, not sure if there was one stock but some do have a oil level sensor.....

code 15 was never coolant level, it means the coolant temp sensor reads way too low or is unplugged

Ok so I just picked a reply button at random.

I may have fixed the SES when warm. I was comparing 1988-91 wiring diagrams and f7 was the "high fan" in 88, f7 was nothing in 89 and the coolant light in the dash in 1990-91 Grand am. I changed my high speed fan settings as a warning temp and wired low as high fan. No light when warm yet and the Idiot light doesn't either. Engine and wiring are from a 1990 Grand am, I will rewire that and see what happens. Ive been really busy so havent checked for broken wires. Ill c if i can try grounding today
