If you’re driving down the road and suddenly your Jeep’s check engine light starts flashing, you may be inclined to think the worst. However, there are actually several common reasons why this light might turn on while you’re driving your Jeep, and only one of them has to do with an actual problem with your vehicle’s engine. 

Check out these common reasons why your check engine light might be flashing and how to figure out if it’s something serious or not.

Why Is My Check Engine Light Flashing?

The check engine light is an important indicator in your car, and it’s one you should never ignore. If you see it blinking, that’s a sign that something is wrong and you should get to a service station as soon as possible. 

There are many potential causes for a flashing check engine light, but some of the most common include: 

  1. A problem with the spark plugs or wires;
  2. A vacuum leak;
  3. A faulty oxygen sensor;
  4. A misfire in the engine;
  5. A problem with the catalytic converter;
  6. If you see your check engine light blinking, don’t panic. But do take it as a warning sign and get your car checked out as soon as possible. A simple repair could save you from paying much more money later on down the line;
  7.  A flickering check engine light means there may be a loose electrical connection somewhere in the vehicle;
  8.  An illuminated check engine light motor indicates there may be an issue with the computer system.

A steady check engine light means that one of these problems has been detected by the computer system and your mechanic will be able to diagnose it from there – It’s always best to keep up with regular maintenance of your vehicle so you can stay on top of any issues like this before they become a major inconvenience. 

Be sure to have your mechanic check the following things during your next visit: tire pressure, air filter, battery connections, brake fluid levels, and make sure that nothing looks unusual under the hood (such as coolant leaking). These are all easy things you can do yourself with a little research beforehand – just be sure not to attempt anything too difficult without first consulting a professional. 

The Dreaded Check Engine Light

If your check engine light is flashing while driving, you need to have it checked out. It’s not just a matter of convenience — it’s a matter of safety.

The flashing check engine light alerts you that there’s something wrong with your car, and it needs to be fixed right away. If ignored, the problem could get worse and lead to more expensive repairs later on.

So if your check engine light is flashing, what should you do? Here’s what you need to know about the flashing check engine light and what to do when you see it.

The check engine light is designed to alert drivers when something is wrong with their vehicle’s emissions system or powertrain — usually immediately before an emission control device fails. When this happens, it can cause poor performance or fuel economy, as well as increase harmful tailpipe emissions (which are typically controlled by these devices).

The most common reason for seeing a flashing check engine light is when there’s a misfire in one or more of your spark plugs or coils. This means one or more cylinders aren’t firing properly — either because they’re not getting enough fuel or too much air (or both). In most cases though, there are other symptoms besides just the check engine light.

The first thing you should do when your check engine light comes on is to take your car to a mechanic. They’ll be able to run a diagnostic test and tell you exactly what’s wrong with your car and whether or not it’s safe to drive.

If the mechanic tells you that your car needs repairs, ask them how long it will take so that you can plan accordingly. If they say they don’t know yet, ask them what they would recommend doing in the meantime (such as driving around town or parking at home).

Minor Issues That Can Cause The Check Engine Light To Appear

There are some minor issues that can be the reason for a flashing check engine light.

Minor issues that can result in a check engine light include:

  • Loose gas cap. This is the most common cause of the check engine light coming on, and it is easily resolved by tightening the gas cap or replacing it if it is damaged or cracked. If you have recently purchased a used car, check to see if the previous owner may have left the gas cap loose.
  • Incomplete software updates. Some vehicles require periodic updates to their computer systems. If the software update was not completed properly or was interrupted, the check engine light will come on as a warning that there is a problem with your car’s emissions system.
  • Faulty oxygen sensor or catalytic converter. These components are used to control how much fuel is burned during normal operation and when you accelerate quickly or brake hard. When they fail, they can cause your vehicle’s performance to be affected as well as increase your fuel economy and emissions levels.
  • Dirty air filter or fuel filter. The air filter cleans dirt out of incoming air and prevents dirt particles from damaging other parts of your engine. A dirty filter can reduce power output significantly and cause poor fuel economy, leading to more frequent trips to fill up at the pump because your vehicle needs more fuel just to get where it needs.
  • Low fuel level. A low level of fuel in the tank can trip many different sensors from telling your car’s computer something is wrong with its fuel system. If this happens often enough, you may need to replace the fuel pump or damaged wiring to fix the problem.

Checking fluids levels and tire pressure regularly helps prevent small problems from becoming larger ones later on down the road. When driving around town or at highway speeds, you should always keep an eye out for leaks under your car, especially if you notice that one particular tire is losing air rapidly.

Key Takeaways

When the check engine light is flashing, it can be a cause for concern. Just to recap:

  1. If your check engine light is flashing, it means your vehicle is in need of immediate maintenance;
  2. Do not ignore a blinking check engine light, as this could indicate a serious problem with your vehicle;
  3. If you see the check engine light flashing, pull over and turn off the engine as soon as possible;
  4. Once you’ve turned off the engine, call a tow truck or roadside assistance to take your car to the nearest service station.

The general idea, however, is simple: it may be a sign of something costly and catastrophic, but might as well be a minor issue. There’s no way to tell until it’s examined by a pro mechanic (or, at least, a skilled enthusiast).
