Yes it can.
All of the engine sensors can affect fuel mileage.
Tires do not have oxygen sensors. They can have pressure sensors. The lack of pressure sensors would have no affect on fuel economy.
Yes, it can affect the oxygen sensors and catalytic converter.Yes, it can affect the oxygen sensors and catalytic converter.
Yes The computer that controls the transmission relies on these to decide when to shift.
Yes, a dead battery will affect the computer. The computer will go to factory default state and enter re-learn mode, recalibrating itself to the specifics of the car. During this time, the Check Engine or Service Engine Soon light might be on. Also, you will not pass an emissions test, as the computer will report that it is still in re-learn mode. Other things, such as the clock and the radio presets, will also need to be reset.
It shouldn't, but if your injectors were dirty, then the O2 sensors probably are too.
yes
Cold weather can decrease the tire pressure causing the tire pressure sensors to trip the low pressure light. Adjust tire pressure in all tires as soon as possible to put out the light. If you adjust the tire pressures and the light remains on after a short drive, you may have other issues such as a faulty sensor. The sensors are battery operated and the battery only last just so long.
There are sensors inside the trans, outside the trans, and on the engine that will all affect shifting.
High temperature shortens battery life.Freezing a battery can kill it.
No. It should not affect your computer files.
