coolant temp sensor issue

[Rob88]

Ok ive searched on the forums no one has seemed to have this exact problem. my coolant temp sensor reads -75 degrees at first when i go out and try to start my car in the morning. after about killing the battery everytime it might start. and then the temp sensor will slowly go up but never goes past about 112 degrees. it throws a CEL with the air temp sensor being bad and the barometric sensor being bad. i have replaced the temp sensor TWICE and cut and rewired the wires back about 6". any ideas? ECU maybe?

If your cooling system isn't full that will happen. Check it in the morning after sitting all night.
