P0118: Engine Coolant Temperature Sensor Circuit High

http://www.autocodes.com/p0118_ford.html

To begin, this year fusion had some issues with overheating problems which seem to be solved by 'bleeding' the coolant system of all air. Historically, an air bubble will become superheated and cause the temp needle on the dash to rise suddenly. This is often mis-diagnosed as a bad sensor, so initially be sure that the system is free of any air and is completely filled with coolant. http://www.fordfusionforum.com/topic/10969-engine-temp-gets-hot-sporadically/ If you do find that this does not solve the problem, and you determine that a sensor replacement is called for, it is always helpful to provide the engine size. The most popular engine was the 2.3 liter, 4 cylinder. If that is your motor, then it has two temp sensors. One is the cylinder head temp sensor and the other being the coolant temp sensor. If you have trouble code P0128, then this could be a result of a stuck thermostat, bad connection to the sensor or a bad sensor as you have determined. The reason I am providing all of this information is that you should eliminate other simple problems before replacing sensors. The temp sensor is located as an attachment to the water outlet adapter on the lower radiator hose. It is identified as part #19 in the attached diagram. http://www.autopartslib.com/2007-2-3l-ford-fusion-radiator-components-parts-diagram/ and is a threaded component. It sells for about $20. A pic of the part can be seen here: http://www.1aauto.com/coolant-temperature-sensor/i/1atsu00022?f=831037&y=2007&utm_campaign=gb_csv_br&utm_content=TSU&gclid=CPe2j_a7zr4CFdRj7AodJQoAvg. Again, I am guessing as to your motor size. Other sizes will have different applications. Good Luck!

This code is a system circuit not a sensor.
P0538 - A/C Evaporator Temperature Circuit High Input

Possible causes- A/C evaporator temperature sensor circuit is open or short
- Poor electrical connection at the evaporator temperature sensor circuit
- Faulty Evaporator Temperature sensor

That is the indicator for getting you to bring it into the shop. The equivalent of service engine soon.

P0128 is the fault code to check 1.the coolant level 2. thermostat defective 3. ECT (engine coolant temperature) sensor defective

For 1997 Pontiac Sunfire 2.2L SFI OHV 4cyl the Coolant Temperature Sensor is located under hood, driver side, upper engine area, below valve cover, mounted in cylinder head.

Hope helps (remember to rate this answer)..
