The fear of the unknown (or the cost of the unknown) can be just as stressful.

When your 2020 Toyota Sienna's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t decent, a computer turns on your check engine light. This amber or yellow light is typically labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an computerized scan tool that is used by our Toyota auto repair mechanics at Nalley Toyota Stonecrest. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you elect for that route too.

A damaged catalytic converter is consistently caused by neglected maintenance, which is why Nalley Toyota Stonecrest offers a complimentary multi-point inspection with every Toyota service.

Your car may run at a higher temperature, too, which can cause distinct problems from overheating.
• Your 2020 Toyota Sienna has a vacuum leak. Every Toyota Sienna has a vacuum system that performs a wide variety of functions. The vacuum system also 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, especially if they’re exposed to exciting heat or extreme cold.
• New Spark Plugs or Plug Wires are imperative for your 2020 Toyota Sienna. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires bring the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are harmful or old, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, large to more expensive repairs.

These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting.

The mass airflow sensor in your Toyota Sienna is what determines how much fuel is imperative 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 actual changes, like altitude. If your Toyota Sienna is having trouble starting, idling rough or has a fast change in the position of the throttle pedal, this could be a sign of a harmful mass airflow sensor.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, acknowledged as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2020 Toyota Sienna's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to learn the right mixture of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a car to fail an emissions test.
• One of the most advantageous and countless cause is that your 2020 Toyota Sienna gas cap is loose, damaged or missing. The gas cap for your 2020 Toyota Sienna 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 harmful fuel cap?
