Check Engine Light Service 2012 Lexus GX 460

What do you do when you’re driving along in your Lexus GX 460 and immediately, 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 value of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t represent you have to pull the vehicle over to the side of the road and call a tow truck, but it is recommended that you get your 2012 Lexus GX 460 checked as soon as authentic. Ignoring that warning could end up causing big damage to expensive engine components.

When your 2012 Lexus GX 460'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 usually 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 pick that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an licensed professional to illustrate the issue and repair it.

How much does it cost to get the engine light checked?

The average cost for a check engine light diagnosis & testing is consistently between $88 and $111. The excellent news, Plaza Lexus offers complimentary multi-point inspections and free diagnostics, in most cases, to help learn the cause of your check engine light. The check engine light warns of issues ranging from a gas cap that's not properly tightened to a more perilous failure like a bad catalytic converter or a problem with one of the car's oxygen sensors, so it excellent to get the fitting code reading and diagnosis.

Will the check engine light reset itself?

The check engine light on your 2012 Lexus GX 460 will frequently 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 acceptable, 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 2012 Lexus GX 460 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.

What could cause the check engine light to come on in a 2012 Lexus GX 460?

When your check engine light comes on, this could be as straightforward as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a treacherous problem that could cause treacherous break to your engine and come with a bizarre repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow customarily means something less treacherous but a flashing check engine light suggests that your vehicle’s engine is in treacherous trouble and service is needed now. If your check engine light is flashing in your 2012 Lexus GX 460, we very recommend not to drive the vehicle and schedule Lexus service today. Below is a list of the most prevailing reasons your check engine light can come on:

  • Your 2012 Lexus GX 460 has a vacuum leak. Every Lexus GX 460 has a vacuum system that performs a wide variety of functions. The vacuum system also helps reduce down bad 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, particularly if they’re exposed to exciting heat or extreme chilled.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or additional item can wreak havoc on your 2012 Lexus GX 460 if it’s not installed accurately. These aftermarket parts and accessories can eject the battery, trigger the check engine light, or even avoid the vehicle from starting. If these issues sound ordinary, bring your GX 460 to Lexus and have our squad of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM parts first place might cost a scant bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Lexus GX 460’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is normally caused by neglected maintenance, which is why Plaza Lexus offers a complimentary multi-point inspection with every Lexus service. If you have an issue with your catalytic converter and don't get it fixed, your 2012 Lexus GX 460 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause additional problems from overheating.
  • The battery is low or dead. The battery in your 2012 Lexus GX 460 is every needed. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car 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 drive, but check our ongoing service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Lexus GX 460 is what determines how much fuel is needed to run your engine efficiently by measuring the payment of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to clear changes, like altitude. If your Lexus GX 460 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.
  • New Spark Plugs or Plug Wires are needed for your 2012 Lexus GX 460. 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 bad or classical, 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, major to more expensive repairs.
  • One of the most ordinary and frequent cause is that your 2012 Lexus GX 460 gas cap is loose, damaged or missing. The gas cap for your 2012 Lexus GX 460 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 bad fuel cap? If your gas cap is classical 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 2012 Lexus GX 460, 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 changed. 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 accessible 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 2012 Lexus GX 460's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to learn the honest mixture 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.
