The 2000 Dodge Durango check engine light is an indicator that something is wrong with your vehicle. When you see the check engine light, it’s important to have it checked out as soon as possible. If ignored, this can lead to more serious problems with your vehicle. Here is the list of most common causes why is your 2000 Dodge Durango check engine light come on:

  • Ignition system problems.
  • Vacuum leaks.
  • Fuel system problems (such as fuel pump failure).
  • The spark plugs are worn out or need to be replaced.
  • Your fuel injectors are clogged with carbon deposits from burning oil, causing poor engine performance.
  • Your engine’s timing is off.

2000 Dodge Durango Check Engine Light Can Be Illuminated By Bad Oxgyen Sensor?

If you’re having problems with your car, there are several things that could be causing the 2000 Dodge Durango check engine light to illuminate. One common cause is a bad oxygen sensor. This device monitors the amount of oxygen in your vehicle’s exhaust system and relays this information to the engine computer so that it can adjust fuel and air mixture accordingly. The oxygen sensor is often referred to as an O2 sensor because it measures the amount of oxygen in your vehicle’s exhaust.

If one or more of these sensors become faulty, they may send incorrect readings to the engine control unit (ECU) which will result in poor performance and reduced fuel economy. If it fails to work properly, it can cause the check engine light to illuminate. When this happens, you need to have your vehicle checked out by a mechanic as soon as possible. If you don’t have checked it, the engine may not be running properly, which can lead to increased fuel consumption and reduced vehicle performance.

What Should I Do If 2000 Dodge Durango Check Engine Light Is Illuminated By A Bad Oxgyen Sensor?

If a bad oxgyen sensor is causing your 2000 Dodge Durango Check Engine Light to illumination and stay on, the first thing you should do is simply turn it off. By this, we mean unplugging the sensor from its harness. This will solve the problem for about two weeks until the internal capacitors charge up again. After two weeks of non-operation, your check engine light should return to normal and stay off.

If this solutions does not work, you need to replace the sensor. It is an easy job that can be done by any mechanic or do-it-yourselfer with a little experience. If you have never replaced an oxgyen sensor before and are unsure of how to go about doing it, we recommend taking your Durango to a shop and having them perform the repair for you. If you continue to have problems with your check engine light staying on, it is recommended that you take your vehicle in for a diagnostic. This way, you can find out exactly what is causing the oxgyen sensor malfunction.
