Likewise, the check engine light could also be a warning of a relentless problem that could cause relentless damage to your engine and come with a enormous repair bill.

If your check engine light is flashing in your 2012 Lincoln Navigator, we extremely recommend not to drive the vehicle and schedule Lincoln service at this moment. Below is a list of the most normal reasons your check engine light can come on:

  • New Spark Plugs or Plug Wires are decisive for your 2012 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. 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 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, leading to more pricey repairs.
  • Your 2012 Lincoln Navigator has a vacuum leak. Every Lincoln Navigator has a vacuum system that performs a wide variety of functions. The vacuum system also 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 bare out and crack, especially if they’re exposed to accomplished heat or extreme pleasant.
  • One of the most known and countless cause is that your 2012 Lincoln Navigator gas cap is loose, damaged or missing. The gas cap for your 2012 Lincoln Navigator 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 pricey. If your check engine light turns on suddenly after you put gas in your 2012 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 catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 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 mostly caused by neglected maintenance, which is why David McDavid Plano Lincoln offers a complimentary multi-point inspection with every Lincoln service. If you have an issue with your catalytic converter and don't get it repaired, your 2012 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 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 faster and your vehicle will be less practical 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 2012 Lincoln Navigator's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to indicate the right mixture 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.
  • Issues with each aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2012 Lincoln Navigator if it’s not installed perfectly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even impede the vehicle from starting. If these issues sound attentive, bring your Navigator to Lincoln and have our department of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing each issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money 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 Lincoln Navigator is what determines how much fuel is decisive 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 aware changes, like altitude. If your Lincoln Navigator is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • The battery is low or dead. The battery in your 2012 Lincoln Navigator is every profound. 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 frequent decades ago, and they don't actually require maintenance.
