My engine light keeps coming on and I used freescan to check the codes and it says "low coolant temp" I forget the number of the code. I replaced both temp sensors and don't know how to get ride of it. Also on freescan my coolant temp is stuck on -40 degrees. I do have a 160 degree thermostat but I need some help.

 

You need to make sure the power and ground leads to the sensor in the water pump is good. Info
