If your check engine light is shining in your 2019 Toyota RAV4, we exceedingly advise not to drive the vehicle and schedule Toyota service today. Below is a list of the most common reasons your check engine light can come on:

  • Your mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Toyota RAV4 is what determines how much fuel is crucial 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 definite changes, like altitude. If your Toyota RAV4 is having trouble starting, idling rough or has a immediate change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • One of the most ongoing and frequent cause is that your 2019 Toyota RAV4 gas cap is loose, damaged or missing. The gas cap for your 2019 Toyota RAV4 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 old 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 2019 Toyota RAV4, original 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.
  • The battery is low or dead. The battery in your 2019 Toyota RAV4 is every fundamental. 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 Toyota you drive, but check our ongoing service coupons and specials.
  • Your O2 Sensor (Oxygen Sensor) needs to be changed. The Oxygen sensor, acknowledged 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 classic 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 2019 Toyota RAV4's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the right 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or additional item can wreak havoc on your 2019 Toyota RAV4 if it’s not installed properly. These aftermarket parts and accessories can jettison the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound ongoing, bring your RAV4 to Toyota and have our squad of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, highly aftermarket parts and accessories, or using OEM parts original place might value a tiny bit more but could save you money from having to get poor work and break caused by poor installation work corrected.
  • New Spark Plugs or Plug Wires are crucial for your 2019 Toyota RAV4. 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 old, 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, best to more expensive repairs.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2019 Toyota RAV4’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 2019 Toyota RAV4 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.
  • Your 2019 Toyota RAV4 has a vacuum leak. Every Toyota RAV4 has a vacuum system that performs a roomy variety of functions. The vacuum system also helps lower 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 bare out and crack, highly if they’re exposed to dominant heat or extreme brisk.
