Hi
Subaru outback 2005 2.5 L automatic
200,000 + miles eng coolant , temp sensor 1 , circuit low
In Alaska bought it five years ago.
it's a good car
For a week problem occuring. screen says 35 miles per gallon im only going 3 miles it's guzzling gas & when turn heat ON not as powerful used to be. check engines on & gauge on H. fans are always on and it has a hard time starting. Just installed a new starter I know that's not the problem.
Just sprayed MAF cleaner is still doing it.
Question is is a thermostat problem or MAF get a new sensor?
Someday I want to be a mechanic. I'm 32 yo woman . But now I'm a dishwasher at a local restaurant
Hope to hear from you!
P0117 idk!?
Here is information on the potential causes of that code and troubleshooting information. , The most common cause is a bad sensor but it could also be a wiring problem or a few other possibilities:

Thanks! 😊
What should I do?
Install air intake system?
Tune up?
The source of the problem needs to be diagnosed. Throwing parts at car problems rarely if ever works and just wastes time and money. Though certainly it's worth checking filters and spark plugs (tune-up) if you don't know when those items were last serviced. You did not mention what your actual gas mileage is under what conditions, or how much it has dropped from when you first bought the car. Those old Subarus with 4-speed automatic transmissions were not known for getting good mileage.
Other than that, for starters you know there's a problem with the coolant temperature sensor or its circuit so I would start troubleshooting in that area.
The worst case scenario would be if there's a blown head gasket which is a very common problem on those cars. You can find a shop manual online for your car here which may be helpful:

temp sensor 1 , circuit low
is this a trouble code you're getting? Sounds like you need to take a closer look at this sensor and its wiring
Given the age and mileage of the car there are a number of things that could be wrong. Be aware that vintage of Subaru is prone to blowing head gaskets.
What are the exact codes you are seeing? Is the car overheating? Coolant level dropping? Do you have access to a scan tool that can read live data?
Thank you so much for reaching out I really really appreciate this.
P0117 idk!?
I don't have the fancy tools to check I just have mechanics and a diagnosi I keep an eye out for the coolant reserver
Would you advise me to drive or not?
Not if it's overheating. Subarus of that time period have enough of a problem with head gaskets without bringing overheating into the picture.
What should I do?
Install air intake system?
Tune up?
Alright alright
Alright alright
Just had cts coolant temp sensor installed December
