What could cause the check engine light to come on in a 2012 Toyota Venza?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Also, the check engine light could again be a warning of a serious problem that could cause serious damage to your engine and come with a hefty and expensive repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow usually means something less serious but a flashing check engine light signifies that your vehicle’s engine is in serious trouble and useful service is required instantly. If your check engine light is flashing in your 2012 Toyota Venza, we tremendously 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:

  • Your 2012 Toyota Venza has a vacuum leak. Each Toyota Venza has a vacuum system that performs a wide variety of functions. The vacuum system again helps lower unhealthy 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, exceptionally if they’re exposed to intense heat or extreme cold.
  • The battery is low or dead. The battery in your 2012 Toyota Venza is each essential. Without a vehicle battery, your vehicle won’t start, light up the road in front, 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 absolutely 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 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 car will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A damaged sensor can not only affect your miles per gallon, but it can cause meaningful damage to your catalytic converter and your 2012 Toyota Venza's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the precisely correct mixture of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can again cause a vehicle to fail an emissions test.
  • One of the most common and frequent cause is that your 2012 Toyota Venza gas cap is loose, broken or missing. The gas cap for your 2012 Toyota Venza serves different purposes. It prevents unpredictable 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 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 expensive. Luckily, to replace a gas cap isn't costly. If your check engine light turns on promptly after you put gas in your 2012 Toyota Venza, 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.
  • New Spark Plugs or Plug Wires are needed for your 2012 Toyota Venza. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your car. 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 experience a noticeable 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 clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more costly repairs.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Toyota Venza’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 Toyota of Greenville offers a free multi-point inspection with each Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your 2012 Toyota Venza 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 dangerous problems from overheating.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2012 Toyota Venza if it’s not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound familiar, bring your Venza to Toyota and have our team of accomplished certified mechanics guarantee that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, exceptionally aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could help you save substantially from having to get poor work and damage caused by poor installation work corrected.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Venza 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 Venza is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a crucial sign of a damaged mass airflow sensor.
