2012 Lexus IS350 Check Engine Light Codes

The check engine light turning on can be quite intimidating to see that small light on your vehicle’s dashboard suddenly brightens, but in reality, it is not something that should cause you to shut down in fear right away. If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. These are automotive computer codes stored by the ECM, also receptive as the OBD (on-board computer diagnostic system) in your IS350. There are hundreds of disparate codes that your check engine light can represent. While that sounds daunting, with a small patience, tackling imperative diagnostics will give you essential knowledge about your car and will also allow that Check Engine Light to do what it is absolutely supposed to do: be your guide. Unfortunately, effortless and correct car symptoms do not always accompany an illuminated Check Engine Light. Since there are hundreds of feasible OBD codes, there are also hundreds of feasible reasons for the light, including:

  • Old Battery
  • O2 Sensor
  • Fuel and air metering systems problems
  • Bad Spark Plugs
  • Emissions controls issues
  • Transmission issues
  • Ignition system faults
  • Loose Gas Cap or Missing Gas Cap
  • Computer output circuit issues

This is why it is terrific for someone who does not have a lot of automotive knowledge to not assume what a code means. Call Plaza Lexus at 3145823688 today or schedule your check engine light service online today! If the engine light comes on due to a critical concern, you risk damaging your car extra by not repairing the issue right away. When your check engine light comes on, you should get it checked out suddenly by a certified Lexus technician.

How many miles can you drive with the check engine light?

Since every check engine code has its own level of severity, it is hard to predict how frequent miles you can drive with the warning light on. It could be anything from a bad sensor to plug wires needing to be replaced. If you check engine light is flashing, we recommend that you pull over and contact Plaza Lexus to help learn if your vehicle is safe to drive in or if we recommend a tow truck. The safest bet is to decipher the code and then plan your strategy accordingly.

Will the check engine light reset itself?

The check engine light on your 2012 Lexus IS350 will generally 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 2012 Lexus IS350 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 transport 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 IS350?

When your check engine light comes on, this could be as effortless as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a critical problem that could cause critical damage to your engine and come with a extensive repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less critical but a blinking check engine light indicates that your vehicle’s engine is in critical trouble and service is decisive shortly. If your check engine light is blinking in your 2012 Lexus IS350, we extremely recommend not to travel to work the vehicle and schedule Lexus service today. Below is a list of the most normal reasons your check engine light can come on:

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2012 Lexus IS350 if it’s not installed perfectly. These aftermarket parts and accessories can deposit the battery, trigger the check engine light, or even prohibit the vehicle from starting. If these issues sound favored, bring your IS350 to Lexus and have our unit of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might price a tiny bit more but could save you money from having to get poor work and break caused by poor installation work corrected.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the sum of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less certain 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 break to your catalytic converter and your 2012 Lexus IS350's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to opt for the right differ 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.
  • New Spark Plugs or Plug Wires are needed for your 2012 Lexus IS350. The spark plugs are the part of your engine that ignites the air/fuel differ 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 your 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 have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or break to ignition coils and O2 sensors, dominant to more expensive repairs.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus IS350 is what determines how much fuel is needed to run your engine efficiently by measuring the sum of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to strong changes, like altitude. If your Lexus IS350 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.
  • The battery is low or dead. The battery in your 2012 Lexus IS350 is every critical. 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 totally require maintenance. The price of a new one depends on the type of Lexus you drive, but check our modern service coupons and specials.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Lexus IS350’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 usually 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 serviced, your 2012 Lexus IS350 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 other problems from overheating.
  • One of the most modern and frequent cause is that your 2012 Lexus IS350 gas cap is loose, damaged or missing. The gas cap for your 2012 Lexus IS350 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 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 straightaway after you put gas in your 2012 Lexus IS350, first thing you should check is to make bold the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2012 Lexus IS350 has a vacuum leak. Every Lexus IS350 has a vacuum system that performs a wide variety of functions. The vacuum system also helps reduce damaging 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 freezing.

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

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