Check Engine Light Service Toyota 4Runner

What do you do when you’re driving along in your Toyota 4Runner and promptly, a yellow light flashes on your dash and says "Check Engine". If you’re like most Toyota 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 find out 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 4Runner checked as soon as accurate. Ignoring that warning could end up causing major damage to costly engine parts.

When your Toyota 4Runner's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t reasonable, a computer turns on your check engine light. This amber or yellow light is normally 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 Toyota auto repair mechanics at Nalley Toyota Union City. There are also a number of relatively bargain code readers that are designed for do-it-yourselfers, should you choose that route too.

What could cause the check engine light to come on in a Toyota 4Runner?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a relentless problem that could cause relentless wear and tear to your engine and come with a large repair bill. Depending on your make and model, the check engine light will illuminate or blink. A prudent glow naturally means something less relentless but a flashing check engine light indicates that your vehicle’s engine is in relentless trouble and service is basic quickly. If your check engine light is flashing in your Toyota 4Runner, we chiefly recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most prevalent reasons your check engine light can come on:

  • One of the most pure and frequent cause is that your Toyota 4Runner gas cap is loose, damaged or missing. The gas cap for your Toyota 4Runner 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 common 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 Toyota 4Runner, authentic thing you should check is to make confident 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 amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less reasonable 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 Toyota 4Runner's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the right mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a vehicle to fail an emissions test.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your Toyota 4Runner’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 frequently caused by neglected maintenance, which is why Nalley Toyota Union City offers a complimentary multi-point inspection with every Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your Toyota 4Runner will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause distinct problems from overheating.
  • Your Toyota 4Runner has a vacuum leak. Every Toyota 4Runner has a vacuum system that performs a extensive variety of functions. The vacuum system also helps discount detrimental 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, highly if they’re exposed to exciting heat or extreme cold.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota 4Runner is what determines how much fuel is needed to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to convenient changes, like altitude. If your Toyota 4Runner is having trouble starting, idling rough or has a fast change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or distinct item can wreak havoc on your Toyota 4Runner if it’s not installed subsequently. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound established, deliver your 4Runner to Toyota and have our unit of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, highly aftermarket parts and accessories, or using OEM parts authentic place might cost a small bit more but could save you money from having to get cheap work and damage caused by cheap installation work corrected.
  • The battery is cheap or dead. The battery in your Toyota 4Runner is 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 truly require maintenance. The price of a new one depends on the type of Toyota you drive, but check our extant service coupons and specials.
  • New Spark Plugs or Plug Wires are needed for your Toyota 4Runner. 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 deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or common, you will experience cheap 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, leading to more expensive repairs.
