The vacuum system again helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, exceptionally if they’re exposed to intense heat or extreme cold.

A broken sensor can not only affect your miles per gallon, but it can cause meaningful damage to your catalytic converter and your 2022 Toyota Sienna's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the specifically correct combination of air and fuel that enters the cylinders in your engine. A broken O2 sensor can again cause a vehicle to fail an emissions test.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2022 Toyota Sienna if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting.
