Ford Repair Questions? Ask a Mechanic for Answers ASAP
Most parts stores will scan for free. If you can get the vehicle scanned and let me know the code or codes we will have some diagnostic direction. It could be as simple as a evap emissions codes like a small leak(very common) loose/leaking gas cap
let me know what engine, 4 cylinder or 6 cylinder and how many miles
as long as the fluids are full and clean and the engine runs good you should be fine to drive to a parts store. They usually have basic function scanners that will pull engine and transmissions codes. I like the 4 cylinder in the fusion better than the 6 cylinder.
I will check for any TSB(technical service bulletins)
great, p0456,p0457 could lead to a bad gas cap in the diagnostic process. This would be the type of issue you would never know if not for the check engine light.
ok, code p0128 could be a thermostat or coolant temp sensor. Just make sure there are no leaks, low coolant could cause this code too.
I did see recently 2 fusions with 4 cylinders get the thermostat replaced for a code, not sure of the code but it did fix the issue.
I would go to the dealer anyway, you are out of basic 3/36.
I have also seen codes set for temp out of threshold on GM vehicles, seems common on newer vehicles for thermostats to set a code like this.
could be a sticking thermostat. I did also just see a fusion for a water pump noise.
This thermostat is a pain to do
The dealer could get 2-2.5 hrs labor for the thermostat. Let me know if this has manual or auto climate control. I would start with making sure the a/c system is full with freon. I have seen many with poor or no a/c due to leaks. with the R134a in the systems it does not take much to leak out. Sops can check with a black light, ford has installed dye in the systems for some time.
you are welcome
I checked for bulletins and did not see anything in regards to a sensor. I do see a evap discharge temp sensor that does require the dash to come off. I have not seen any sensor issues, have done a few compressors and O rings/seals.
