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

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 again be a warning of a significant problem that could cause serious damage to your engine and come with a hefty and pricey repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow typically means something less serious but a flashing check engine light reveals that your vehicle’s engine is in meaningful trouble and useful service is required instantly. If your check engine light is flashing in your Toyota Tacoma, we very endorse 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:

  • One of the most common and frequent cause is that your Toyota Tacoma gas cap is loose, broken or missing. The gas cap for your Toyota Tacoma serves multiple purposes. It prevents dangerous gas fumes from being released when you aren't driving, it seals the fuel system and helps control pressure within the fuel tank. What occurs if you have a damaged 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 and be more costly. Luckily, to change a gas cap isn't pricey. If your check engine light turns on swiftly after you put gas in your Toyota Tacoma, 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 catalytic converter is bad or going bad. The catalytic converter is a part of your Toyota Tacoma’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is usually caused by regularly neglected maintenance, which is why Larry H. Miller Toyota Peoria offers a complimentary multi-point examination with each Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your Toyota Tacoma 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 other perilous problems from overheating.
  • 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 more instantly and your vehicle will be less efficient when it comes to fuel economy. So what occurs if I don’t change your O2 sensor? A damaged sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your Toyota Tacoma's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the specifically correct mixture of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can also cause a vehicle to fail an emissions test.
  • Your Toyota Tacoma has a vacuum leak. Each Toyota Tacoma has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower adverse 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 intense heat or extreme cold.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Toyota Tacoma if it’s not installed correctly. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even limit the vehicle from starting. If these issues sound familiar, bring your Tacoma to Toyota and have our team of accomplished certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could support you save substantially from having to get poor work and damage caused by poor installation work corrected.
  • New Spark Plugs or Plug Wires are needed for your Toyota Tacoma. 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 smooth. 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 undergo a evident poor performance and decreased power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause obstructed catalytic converter or damage to ignition coils and O2 sensors, leading to more pricey repairs.
  • The battery is low or dead. The battery in your Toyota Tacoma is each essential. 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 genuinely require maintenance. The price of a new one depends on the type of Toyota you drive, but check our current service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Tacoma 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 certain changes, like altitude. If your Toyota Tacoma is having trouble starting, idling rough or has a sudden fast change in the position of the throttle pedal, this could be a critical sign of a damaged mass airflow sensor.

Will the check engine light reset itself?

The check engine light on your Toyota Tacoma will ordinarily 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 swiftly turn itself off. Again, if your catalytic converter is working perfectly, 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 Tacoma 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 Larry H. Miller Toyota Peoria so the light and code can be double-checked and reset.

Miller Toyota Peoria to support determine if your vehicle is safe to drive in or if we recommend a tow truck.
