What could cause the check engine light to come on in a Chevy Tahoe?

When your check engine light comes on, this could be as plain as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a extraordinary problem that could cause extraordinary damage to your engine and come with a considerable repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less extraordinary but a flashing check engine light indicates that your vehicle’s engine is in extraordinary trouble and service is basic today. If your check engine light is flashing in your Chevy Tahoe, we notably advocate not to drive the vehicle and schedule Chevy service today. Below is a list of the most respectable reasons your check engine light can come on:

  • One of the most affable and frequent cause is that your Chevy Tahoe gas cap is loose, damaged or missing. The gas cap for your Chevy Tahoe 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 former 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 Chevy Tahoe, 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 Chevy Tahoe’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 usually caused by neglected maintenance, which is why Bill Estes Chevy Indianapolis offers a complimentary multi-point inspection with every Chevy service. If you have an issue with your catalytic converter and don't get it repaired, your Chevy Tahoe 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 distinct problems from overheating.
  • The battery is poor or dead. The battery in your Chevy Tahoe is every alluring. 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 Chevy you drive, but check our current service coupons and specials.
  • New Spark Plugs or Plug Wires are needed for your Chevy Tahoe. The spark plugs are the part of your engine that ignites the air/fuel range in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires bring the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or former, 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, best to more expensive repairs.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or distinct item can wreak havoc on your Chevy Tahoe if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound affable, bring your Tahoe to Chevy and have our team of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a slight bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the reward of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less suitable 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 Chevy Tahoe's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to suggest the right range 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.
  • Your Chevy Tahoe has a vacuum leak. Every Chevy Tahoe has a vacuum system that performs a wide range of functions. The vacuum system also helps decrease 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 bare out and crack, especially if they’re exposed to intense heat or extreme freezing.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Chevy Tahoe is what determines how much fuel is needed to run your engine efficiently by measuring the reward of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to actual changes, like altitude. If your Chevy Tahoe 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.
