What to Do When Your Volkswagen Engine Struggles to Accelerate From Experts in Green Bay

Volkswagen is a very popular car that is well known for its performance and design. Most people prefer a Volkswagen over other cars because of its reliability. Moreover, Volkswagen cars come equipped with many advanced features and accessories that help in the smooth running and better performance of the car.

However, off-late drivers have often complained about facing issues in their Volkswagen cars. One such widely reported problem is about acceleration issues in their car. It is really frustrating when you expect certain acceleration from the car only to find that the vehicle seems to be hesitant while pressing the gas pedal.

The engine of your Volkswagen is very powerful; however, acceleration issues can crop up due to various factors. Most of the time it is seen that vehicle owners don’t take these issues seriously when the problem is at the initial stage. It is very important to know the factors that cause acceleration hesitancy in your Volkswagen.

Here in this article, we will discuss the factors that cause your engine to struggle for acceleration.

Defective mass airflow sensor

The mass airflow sensor in your car is a crucial component that is responsible for monitoring the amount of air entering the engine for the proper combustion process. For complete combustion of fuel, the ratio of fuel-to-air must be adequate in the engine.

The mass airflow sensor gives this information to the onboard computer so that the right amount of fuel can be delivered from the fuel injectors of your Volkswagen. When the mass airflow sensor of your VW malfunctions, it adversely affects the flow of fuel into the engine and this in turn leads to acceleration trouble in your car.

Fuel pump failure

In most modern cars including your Volkswagen, the fuel pump is located inside the fuel tank and pumps the fuel up to the engine. The fuel pump needs to be at the correct pressure so that the fuel gets pumped into the engine without any difficulty.

However, if the fuel pump in your Volkswagen fails, then the adequate amount of pressure cannot be maintained and the proper amount of fuel will not reach the engine. If you observe that your VW is hesitating to accelerate when driving up a hill, then it is having a weak fuel pump.

Malfunctioning throttle position sensor

There are various sensors in your Volkswagen that monitor the functioning of the important parts in the car. The throttle position sensor is one such part that informs the computer how far the throttle is open and how hard the accelerator is being pressed.

The computer in your VW is then able to adjust the fuel/air mixture going to the engine so that it remains in an appropriate level for proper combustion. If the throttle position sensor in your Volkswagen has malfunctioned, it will send incorrect information to the computer.

Due to this, the computer may not be sending the proper amount of air to the engine while accelerating and this causes acceleration hesitation in your car.

Dirty or faulty fuel injectors

The fuel injectors in your Volkswagen are responsible for spraying fuel in a fine mist into the cylinder where it is mixed with the air and ignited by a spark plug. The fuel injectors in your car might get dirty in due course of time and will not be able to provide as much fuel to the cylinder as is needed.

The dirty fuel injectors may cause the engine to run lean which will in turn cause hesitation when you try to accelerate your car.

How to handle the problem

The best way to deal with any kind of acceleration issues in your Volkswagen is to take the car to a certified repair shop where the licensed mechanics will use a code reader to identify the exact cause behind the problem. In addition to reading the trouble codes, the mechanic will also be able to get the readings of oxygen/fuel intake.

If there is any defect detected in any of the systems like the mass airflow sensor, fuel injector, throttle position sensor, or fuel pump then the defective system is replaced.

Finally

The above-discussed factors are some of the leading reasons behind the engine of your Volkswagen struggling to accelerate when you press the gas pedal.
