What could cause the check engine light to come on in a 2021 Lincoln Navigator?
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 still be a warning of a significant problem that could cause serious damage to your engine and come with a hefty and costly repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow ordinarily means something less serious but a flashing check engine light indicates that your vehicle’s engine is in significant trouble and helpful service is needed quickly. If your check engine light is flashing in your 2021 Lincoln Navigator, we tremendously propose not to drive the vehicle and schedule Lincoln service today. Below is a list of the most common reasons your check engine light can come on:
- Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2021 Lincoln Navigator’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 consistently neglected maintenance, which is why David McDavid Frisco Lincoln offers a free multi-point check with every Lincoln service. If you have an issue with your catalytic converter and don't get it repaired, your 2021 Lincoln Navigator 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.
- One of the most common and frequent cause is that your 2021 Lincoln Navigator gas cap is loose, damaged or missing. The gas cap for your 2021 Lincoln Navigator serves multiple purposes. It prevents perilous 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 costly. Luckily, to replace a gas cap isn't costly. If your check engine light turns on quickly after you put gas in your 2021 Lincoln Navigator, 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 2021 Lincoln Navigator has a vacuum leak. Every Lincoln Navigator has a vacuum system that performs a wide variety of functions. The vacuum system likewise 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.
- New Spark Plugs or Plug Wires are needed for your 2021 Lincoln Navigator. 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 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 mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lincoln Navigator 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 Lincoln Navigator is having trouble starting, idling rough or has a sudden fast change in the position of the throttle pedal, this could be a important sign of a damaged mass airflow sensor.
- 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 expeditiously 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 2021 Lincoln Navigator'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 likewise cause a car to fail an emissions test.
- Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2021 Lincoln Navigator 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.
