Check Engine Light Service Toyota RAV4

What do you do when you’re driving along in your Toyota RAV4 and hastily, a yellow light illuminates 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 suggest 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 RAV4 checked as soon as possible. Ignoring that warning could end up causing large wear and tear to expensive engine components.

When your Toyota RAV4's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the computerized 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 Toyota auto repair mechanics at Nalley Toyota Union City. There are also a number of relatively economical code readers that are designed for do-it-yourselfers, should you opt for that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an skilled professional to learn the issue and repair it.

What could cause the check engine light to come on in a Toyota RAV4?

When your check engine light comes on, this could be as authentic as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a hazardous problem that could cause hazardous damage to your engine and come with a compelling repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something fewer hazardous but a flashing check engine light indicates that your vehicle’s engine is in hazardous trouble and service is needed expeditiously. If your check engine light is flashing in your Toyota RAV4, we highly advise not to drive the car and schedule Toyota service at this moment. Below is a list of the most respectable reasons your check engine light can come on:

  • New Spark Plugs or Plug Wires are mandatory for your Toyota RAV4. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your automobile. 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 detrimental 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 damage to ignition coils and O2 sensors, first-rate to more expensive repairs.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, accepted 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 automobile will be less convincing 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 RAV4's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to embrace the right mixture of air and fuel that enters the cylinders in your engine. A detrimental O2 sensor can also cause a car to fail an emissions test.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota RAV4 is what determines how much fuel is mandatory 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 exact changes, like altitude. If your Toyota RAV4 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 detrimental mass airflow sensor.
  • Issues with each aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your Toyota RAV4 if it’s not installed properly. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even prevent the automobile from starting. If these issues sound typical, bring your RAV4 to Toyota and have our squad of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing each issue. Getting accessories, notably aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor perform and damage caused by poor installation perform corrected.
  • The battery is low or dead. The battery in your Toyota RAV4 is every momentous. 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 various decades ago, and they don't truly require maintenance. The cost of a new one depends on the type of Toyota you drive, but check our ongoing service coupons and specials.
  • Your Toyota RAV4 has a vacuum leak. Every Toyota RAV4 has a vacuum system that performs a wide variety of functions. The vacuum system also helps reduction in cost 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 dry out and crack, notably if they’re exposed to active heat or extreme frigid.
  • Your catalytic converter is detrimental or going detrimental. The catalytic converter is a part of your Toyota RAV4’s exhaust system. The catalytic converter's perform 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 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 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 alternative problems from overheating.
  • One of the most sufficient and bountiful cause is that your Toyota RAV4 gas cap is loose, damaged or missing. The gas cap for your 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 detrimental 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 hastily after you put gas in your Toyota RAV4, 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.

Toyota RAV4 Check Engine Light Codes

The check engine light turning on can be quite intimidating to see that scant light on your vehicle’s dashboard suddenly illuminates, 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 legal as the OBD (on-board computer diagnostic system) in your RAV4. There are hundreds of distinctive codes that your check engine light can represent. While that sounds daunting, with a scant patience, tackling rare diagnostics will give you friendly knowledge about your vehicle and will also allow that Check Engine Light to do what it is really supposed to do: be your guide. Unfortunately, compelling and normal vehicle symptoms do not always accompany an illuminated Check Engine Light. Since there are hundreds of functional OBD codes, there are also hundreds of functional reasons for the light, including:

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

This is why it is decisive for someone who does not have a lot of automotive knowledge to not assume what a code means. If the engine light comes on due to a strict concern, you risk damaging your car further by not repairing the issue right away. When your check engine light comes on, you should get it checked out swiftly by a certified Toyota mechanic.

Will the check engine light reset itself?

The check engine light on your Toyota RAV4 will usually 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 effective, 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 Toyota RAV4 light will go off after about 20-40 miles. If you drive over that sum and the light is still on, you will need to bring it in to Nalley Toyota Union City so the light and code can be double-checked and reset.
