How Do I Know If the Dodge Avenger Check Engine Light Could Be a False Alarm? (2023)


If you’re looking for a way to determine whether or not the Dodge Avenger check engine light could be a false alarm, there are several things that you can do. First, take a look at your car’s documentation to see if there are any recalls that might have been issued for this kind of problem. If there haven’t been any recalls issued, then start by making sure that all of your tires are properly inflated and check for any signs of leaks or damage.

If you don’t see any leaks, then try to determine whether or not the car is running properly by taking it on a test drive. If you notice that your vehicle is hesitating or struggling to accelerate, then this could indicate that there is something wrong with one of your oxygen sensors. If everything looks good, then you can start a diagnostic test to see if the check engine light is actually on. If it’s not, then there’s a good chance that the issue was just an error.

If the Dodge Avenger Check Engine Light Comes On, Can I Fix It Myself?

It is possible to diagnose and fix some Dodge Avenger check engine light issues yourself, depending on your level of mechanical experience and the specific problem that is causing the check engine light to come on. Here are some tips if you want to fix it yourself:

  • Check the gas cap: A loose or damaged gas cap can cause the check engine light to come on, possibly indicating a more serious problem. Be sure that the gas cap is on tightly.
  • Check the air filter: A dirty or clogged air filter can cause the check engine light to come on. The air filter, if it is clogged or dirty, can cause the engine to stall.
  • Check the spark plugs: Faulty spark plugs can cause the check engine light to illuminate on your dashboard.
  • Check the oxygen sensor: A failed oxygen sensor can cause the check engine light to come on. If you replace the oxygen sensor, then your engine should stop misfiring.

If you are not confident in your mechanical skills or if the problem persists after trying the above steps, it’s a good idea to have a mechanic diagnose and fix the problem. It’s important to diagnose and fix the problem as soon as possible to avoid any potential issues that could affect the performance or safety of your vehicle.
