Lexus IS250 Check Engine Light

A flashing light indicates that the problem is thoughtful and if not taken care of abruptly may result in best damage to the vehicle. If the check engine light in your Lexus IS250 starts flashing, that means that the problem needs sudden attention and your Lexus should be brought in abruptly. This blinking light usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system. There it can quickly raise the temperature of the catalytic converter to a point where damage is likely, requiring an expensive repair. Some owners ask if spark plugs cause the check engine light to flash? This can absolutely be the cause. A bad, old or dirty spark plug can cause the engine to misfire. If the problem is ignored or you continue to drive, this can spread to the spark plug wires, catalytic converter, or ignition coils which can lead to a especially pricey repair.

Check Engine Light Service Lexus IS250

What do you do when you’re driving along in your Lexus IS250 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 IS250 checked as soon as possible. Ignoring that warning could end up causing major damage to expensive engine components.

When your Lexus IS250'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.

Is it safe to drive your Lexus IS250 with the check engine light on?

If the check engine light is flashing, this means that there is a strict issue and it is recommended to service your Lexus IS250 abruptly. This question is not very clear because it all depends on the severity of the issue. If the cause is a minor issue, such as a loose gas cap, it should be reliable to drive. This is normally indicated by a consistent glow of the check engine light. If you notice a variety in the performance of the vehicle, it could be an indication of a more severe problem.

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 IS250 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.

The vacuum system also helps cut 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 bare out and crack, particularly if they’re exposed to notable heat or extreme freezing.

If your Lexus IS250 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.
  • 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 Lexus IS250's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the honorable range 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.
