Will the check engine light reset itself?

The check engine light on your Lexus IS 200t will usually shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your Lexus IS 200t light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Plaza Lexus so the light and code can be double-checked and reset.

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 imposing heat or extreme cold.

As a part of the engine management system, the mass airflow sensor helps adjust to conscientious changes, like altitude. If your Lexus IS 200t 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.
  • One of the most chummy and frequent cause is that your Lexus IS 200t gas cap is loose, damaged or missing. The gas cap for your Lexus IS 200t 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 own a bad fuel cap? If your gas cap is long-established or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on immediately after you put gas in your Lexus IS 200t, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the payment of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less dominant when it comes to fuel economy.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your Lexus IS 200t’s exhaust system. The catalytic converter's work is to turn the carbon monoxide created by the combustion process into carbon dioxide.

  • The battery is low or dead. The battery in you Lexus IS 200t every vital. Without a vehicle battery, your vehicle won’t start, light up the road ahead, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't really require maintenance. The price of a new one depends on the type of Lexus you travel to work, but check our current service coupons and specials.
  • New Spark Plugs or Plug Wires are decisive for your Lexus IS 200t. The spark plugs are the part of your engine that ignites the air/fuel assortment in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If you're spark plugs or spark plug wires are bad or long-established, you will experience poor performance and reduced power. In some extreme cases, your engine will own 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, big to more expensive repairs.

Check Engine Light Service Lexus IS 200t

What do you do when you’re driving along in your Lexus IS 200t and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Lexus owners, your heart sinks a little because you have little idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. 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 Lexus IS 200t checked as soon as possible. Ignoring that warning could end up causing major damage to expensive engine components.

When your Lexus IS 200t'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. 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 electronic scan tool that is used by our Lexus auto repair mechanics at Plaza Lexus. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the issue and repair it.
