Your Dodge Avenger frequently stalls when the engine is cold, but only in that situation, and not at all when the engine is hot, and you have trouble finding its origin? This problem, although less dangerous than an engine that stalls while driving, nonetheless deserves your attention because it could be the start of a more significant problem in the future.
In this article, we will tell you about the various problems you might deal with when your car stagger in cold start so that you can react more efficently and not necessarily go to the garage, which often charges a high price for the service and does not always solve the problem.

Different motives to stall for a cold engine.

First, we will discuss failures related to mechanical problems. The second part will be focused to electronic problems.Stalls-when-cold-dodge-avenger

1: Mechanical failures on your Dodge Avenger

First thing to think about, the idle actuator. As a reminder, the latter’s role is to control the engine speed. It may be difficult for the latter to connect to the engine while the engine is still cold.
Another simpler consideration, but also common in these cases, is that the battery is likely low, and therefore does not have many reserves till the engine has started. This should tell you that after “heating” the engine, the battery has accumulated enough energy to keep your Dodge Avenger on. Even so, it has difficulty maintaining autonomy once the engine is switched off. Which would explain why it only chockes cold.
Also bear in mind to check your dashboard, and if, by any chance, an indicator light is not lit.
Then again, if your car always starts the first time, it is very likely that it does not come from your battery.
If the battery is not involved, look at some of the parts to be cleaned, such as filters, injection pump, or pressure regulator.
Take into account that a simple, heavily soiled part can disrupt the entire mechanism of your Dodge Avenger. Verify all your parts to be able to exclude this type of failure.
Once mechanical breakdowns and fouling have been put aside, let’s try to look for electronic parts that could cause you problems.

2: Electronic failures of your Dodge Avenger

The first important parts are the onboard computer. the MCU (Motor Control Unit) acts as a system for exchanging and sending information throughout your vehicle. Electrical signals are received, analysed and sent back as information to the various parts of your Dodge Avenger.
For example, when you activate your indicator, your MCU box receives the information, processes it, and then redirects it to your flashing room, which will then light up. We have used here the example of the indicator, which would not stop you from driving. If this information was associated to the engine of your Dodge Avenger, then in this case it may stall cold.
Furthermore, let us focus on the calculator. This essential part of your vehicle is a central element of a system called an embedded system. This means that it electronically deals with the various functions of your vehicle, and therefore the ignition of the engine.

Directly linked to your computer, the TDC sensor.

Actually ,the internal combustion motor must have an accurate ignition timing setting to be able for all the cylinders to fire in the correct order and at a specific moment. If the TDC sensor is damaged, it will not send this information to the onboard computer. Therefore ,, as a safety measure, the ECU will prevent the ignition system and your Dodge Avenger won’t start.

Finally, you could possibly want to check your alternator.
It is essential for the engine to start because it turns the battery on, and the engine producesthe electricity required to keep the battery charged while you drive.
This means that ultimately you could have a battery problem. If your alternator does not provide enough electricity to your battery, it will, therefore, be unable to keep your Dodge Avenger on.

3: Conclusion

As we have seen in these various motives of cold stalling cars, this often leads back to the battery or directly affiliated parts. However, this may not be the only cause, do all the necessary tests to analyze the proper functioning of each part. Finally, the last thing to think about with Dodge Avenger is to ask yourself this question: have you fairly recently started refuelling at a new gas station? In this case, it may be unintentionally degraded due to contact with water or impurities. This would impact your engine, which could start to stall quickly.
However, if this does not appear immediately after your engine is hot, then the impurity of the fuel is exonarated. The problem would be repeated no matter if your engine is hot or cold.
