Check Engine Light Service Chevy Tahoe

What do you do when you’re driving along in your Chevy Tahoe and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Chevy owners, your heart sinks drastically because you may have explicitly 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, tranquil breath and realize the light coming on doesn’t mean you have to pull the vehicle over to the side of the road and call a tow truck, but it is suggested that you get your Chevy Tahoe checked instantly. Ignoring that warning could end up causing major, major damage to pricey engine components.

When your Chevy Tahoe's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic 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 can promptly identify 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 Chevy auto repair mechanics at Bill Estes Chevy Buick GMC Lebanon. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you pick that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the definitely correct issue and repair it.

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 simple as tightening or replacing your gas cap. Also, the check engine light could again be a warning of a meaningful 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 reveals that your vehicle’s engine is in meaningful trouble and helpful service is required promptly. If your check engine light is flashing in your Chevy Tahoe, we very propose not to drive the vehicle and schedule Chevy service today. Below is a list of the most common reasons your check engine light can come on:

  • Your Chevy Tahoe has a vacuum leak. Every Chevy Tahoe has a vacuum system that performs a wide variety of functions. The vacuum system again helps lower 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, exceptionally if they’re exposed to intense heat or extreme cold.
  • 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 necessary 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 Chevy Tahoe is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a vital sign of a damaged mass airflow sensor.
  • 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 broken catalytic converter is frequently caused by constantly neglected maintenance, which is why Bill Estes Chevy Buick GMC Lebanon offers a free multi-point check 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 other delicate problems from overheating.
  • New Spark Plugs or Plug Wires are necessary for your Chevy Tahoe. 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 experience a evident 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, leading to more costly repairs.
  • 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 quickly and your vehicle 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 significant damage to your catalytic converter and your Chevy Tahoe's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the absolutely correct mixture of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can again cause a car to fail an emissions test.
  • One of the most common and frequent cause is that your Chevy Tahoe gas cap is loose, broken or missing. The gas cap for your Chevy Tahoe serves multiple purposes. It prevents hazardous 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 pricey. Luckily, to replace a gas cap isn't costly. If your check engine light turns on quickly 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.
  • The battery is low or dead. The battery in your Chevy Tahoe is every important. Without a car battery, your car won’t start, light up the road in front, 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 absolutely require maintenance. The price of a new one depends on the type of Chevy you drive, but check our current service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your Chevy Tahoe if it’s not installed accurately. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound familiar, bring your Tahoe to Chevy and have our team of accomplished certified mechanics assure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, exceptionally aftermarket parts and accessories, or utilizing OEM components first place might cost a little bit more but could help you save considerably from having to get poor work and damage caused by poor installation work corrected.

Will the check engine light reset itself?

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. Also, 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 Chevy Tahoe 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 Bill Estes Chevy Buick GMC Lebanon so the light and code can be double-checked and reset.
