Over time, vacuum hoses can dry out and crack, notably if they’re exposed to dominant heat or extreme nice.

Your car may run at a higher temperature, too, which can cause added problems from overheating.

The mass airflow sensor in your Toyota Avalon is what determines how much fuel is necessary to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to specific changes, like altitude. If your Toyota Avalon is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.

A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your Toyota Avalon's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean the right mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
• One of the most classical and copious cause is that your Toyota Avalon gas cap is loose, damaged or missing. The gas cap for your Toyota Avalon serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap?
