2006 Mercury Milan Question: How to fix coolant temp sensor?
Code can be set for many reasons besides temp sensor failure.Get service manual (consider that your treat $ , for doing the labor yourself!). then check the wires(circuit) and test the sensor before replacing it.You didn't give a specific code # , that's why I say there are many variables. A stuck-open thermostat can set a coolant temp 'out-of-range' reading etc.. - ziptie12
