All of the engine sensors can affect fuel mileage.
yes
Tires do not have oxygen sensors. They can have pressure sensors. The lack of pressure sensors would have no affect on fuel economy.
As much as the dealership was willing to give you. Value of the vehicle depends on options, mileage, overall condition, demand, and retention value. What you're trading it in towards will also affect it... you'll get more to trade it in for a new car than for a used car.
If this vehicle has high mileage I would start with the plug\wires and oxygen sensors. These would all affect fuel mileage on higher mileage vehicles. Hope this helps you.
To disable the all-wheel drive system in a 2000 Subaru Forester, you can remove the 15-amp fuse located in the fuse box under the hood, specifically the fuse labeled for the center differential. However, it's important to note that disabling the all-wheel drive can negatively affect vehicle performance and safety, so it should be done with caution and ideally only for diagnostic purposes.
any of the oxygen sensors could affect gas mileage but usually the first one in the exhaust pipe on either side causes the most driveabilty issues.
Yes, it can affect the oxygen sensors and catalytic converter.Yes, it can affect the oxygen sensors and catalytic converter.
The quick answer is "Yes, cold weather affects everything that moves." Your Subaru was designed to withstand the temperature extremes that this planet experiences. Componnents that are already close to failure are placed under increased stress at temperature extremes and failure may come more quickly at those times. Does this help? --Ken
To fix the auto-dimming mirror in a 2001 Subaru Forester, first, check the wiring and connections to ensure they are secure and free from corrosion. If the mirror is still not functioning, inspect the ambient light sensor, usually located on the front of the mirror, for damage or obstruction. If necessary, replace the mirror assembly, as these components can fail over time. Finally, ensure the vehicle's electrical system is functioning properly, as issues with the battery or fuses can also affect the mirror's operation.
If it is malfunctioning it can affect fuel mileage.
no.
