This is why it is amusing for someone who does not have a lot of automotive knowledge to not assume what a code means. Since there are hundreds of likely OBD codes, there are also hundreds of likely reasons for the light, including: Unfortunately, distinguishable and fundamental car symptoms do not always accompany an illuminated Check Engine Light. While that sounds daunting, with a microscopic patience, tackling necessary diagnostics will give you accessible knowledge about your car and will also allow that Check Engine Light to do what it is surely supposed to do: be your guide. There are hundreds of disparate codes that your check engine light can represent. These are automotive computer codes stored by the ECM, also known as the OBD (on-board computer diagnostic system) in your Sienna. If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. The check engine light turning on can be quite intimidating to see that microscopic light on your vehicle’s dashboard suddenly illuminates, but in reality, it is not something that should cause you to shut down in fear right away.

If your check engine light is on in your Toyota Sienna, contact Nalley Toyota Stonecrest. It can be as classic as your gas cap being loose or as active as engine knocking. With that being said, the check engine light can represent a variety of supplemental things. Some of these include shifting automatic transmissions ignition timing, controlling engine speed, and implementing stability control, just to name innumerable. Onboard computers increasingly have controlled and monitored vehicle performance since the 80s and do a variety of things for your Toyota Sienna. This light illuminates in either an amber or red color and is part of the diagnostics system found on your vehicle. It can say "Check Engine", it can be a symbol of an engine, it can even be a combination of both. The check engine light is part of the onboard diagnostics system, and displays in a few diversified ways. One of the most generally misunderstood lights or indicators in your Toyota Sienna is the check engine light. The safest bet is to decipher the code and then plan your strategy perfectly. It could be anything from a bad sensor to plug wires needing to be replaced. If you check engine light is glaring, we recommend that you pull over and contact Nalley Toyota Stonecrest to help choose if your vehicle is safe to drive in or if we recommend a tow truck. Since each check engine code has its own level of severity, it is difficult to predict how bountiful miles you can drive with the warning light on. How many miles can you drive with the check engine light? While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to find out the issue and repair it. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. This code is read with an electronic diagnose tool that is used by our Toyota auto repair mechanics at Nalley Toyota Stonecrest. 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 amber or yellow light is generally 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 your 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 correct, a computer turns on your check engine light. Ignoring that warning could end up causing big wear and tear to costly engine components. But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your Toyota Sienna checked as soon as functional. The fear of the unknown (or the price of the unknown) can be just as stressful. If you’re like most Toyota owners, your heart sinks a miniature because you have miniature idea about what that light is trying to tell you or how you should react. What do you do when you’re driving along in your Toyota Sienna and suddenly, a yellow light illuminates on your dash and says "Check Engine".
