Causes of Car Loss of Power During Acceleration

Causes of Car Loss of Power During Acceleration – If you are driving a car and find that your car loses power during acceleration, there can only be one of two reasons for this. Either you don’t have enough fuel in your car’s tank or you don’t have enough power. And there are many reasons why your vehicle loses power, especially during acceleration. Some of the causes are mechanical problems. Causes of loss of power during acceleration in the category of mechanical problems can occur such as weak compression, blockage of the fuel filter, dirty air filter, or blockage of the exhaust gas line. Next is the malfunction of sensors such as the camshaft position sensor, MAF sensor, oxygen sensor, crankshaft sensor, and all sensors seen with the EFI system. Or malfunctioning actuators such as bad injection, abnormal fuel pump, and also improperly ignited spark plugs.

Causes of Car Loss of Power During Acceleration

Causes of Car Loss of Power
Poor acceleration is the result of a faulty sensor, but it can also be from something as trivial as a dirty air filter.

The cause of the car losing power is a common cause. Although in general the same but there are still slight differences that occur in gasoline and diesel engines. Therefore, this article on the Causes of Car Loss of Power During Acceleration will explain these differences.

Low Compression

Compression is important and very important in a vehicle. Low compression is certain to interfere with the work of the engine as a whole. Especially in relation to the power generated by the engine. The decrease in power will be felt, especially when accelerating. So this is one of the causes of loss of power during the first acceleration.

Clogged Fuel Filter

Causes of Car Loss of Power
A dirty fuel filter can cause slowed car acceleration.

The fuel filter is located between the fuel injector and the fuel pump of each car. The job of the fuel filter is to filter the fuel for any possible impurities in it. When the fuel pump delivers fuel into the engine, fuel impurities will not appear. The fuel filter becomes a fortress that blocks impurities in the fuel. If the fuel filter on your car is dirty or even damaged then it may not work in the condition it should. When damage or dirt is experienced by the fuel filter, the impurities that flow with the fuel cannot be filtered out. And finally into the combustion chamber (engine). If this happens, the machine will lose its power and the whole machine will experience interference.

Bad Air Filter (Broken)

The combustion chamber in an engine is where the fuel and air mixture come together to generate the power needed to run your vehicle. Before the air enters the combustion chamber, the air must pass through an air filter that filters such as insects, dust, or other types of dirt that make the air impure. If air impurities enter the engine, it can harm the engine. However, clogged air filters are also possible in prolonged use. If the air filter is clogged, the air filter will limit the amount of air that enters the combustion chamber. This will have a negative impact on the function of the vehicle. Because the engine will not be able to generate enough power to run the vehicle.

Clogged Combustion Sewer

Blockages in the exhaust duct of the combustion residue from the engine are often not realized by the driver or mechanic. Basically, there are two fuel exhaust pipes namely the muffler and the catalyst converter. The catalyst converter’s job is to reduce the amount of pollution generated from exhaust gases. Meanwhile, the muffler is responsible for reducing the noise level made by the exhaust gases. If the drainpipe is clogged, it will result in the weakening of the engine function. The main thing is the reduction of engine power. So the vehicle moves slowly when we try to accelerate.

Camshaft Position Sensor Not Working

Causes of Car Loss of Power
Dirty CMP sensor can result in abnormal camshaft rotation readings and result in impaired acceleration.

The vehicle’s camshaft position sensor responds to information about the vehicle’s camshaft speed. This response information is then sent to the electronic control module (ECM). This module is a computer that is in almost all new cars today. Camshaft speed information is sent to the ECM, which then determines the ignition timing and fuel injection. However, if there is a problem with this sensor and it is unable to transmit information to the ECM, it will seriously affect the engine performance. As a result, the machine will not be able to function as it should. This also includes causing low power during acceleration.

MAF Sensor Not Working

Note, this sensor is only available on gasoline engines. The main job of the MAF (mass airflow) sensor is to measure the amount of air passing through the engine. It then reports this number to the Powertrain Control Module. From there, the module will use this information to calculate the load placed on the machine. If there are some problems with this sensor, then the engine performance will be greatly reduced.

Weak or Bad Fuel Pump

This section applies only to gasoline engines. The fuel pump is in charge of bringing fuel from the tank and transferring it to your car’s engine. Not only that, the pump ensures that the fuel is delivered at high pressure in such a way that it can maximize engine performance. If there is some malfunction or malfunction of the fuel pump, there will be a problem with the engine. Especially the problem with vehicle acceleration.

Broken Spark Plug

Causes of Car Loss of Power
Faulty spark plugs can cause throttled acceleration.

This section applies only to engines running on gasoline. Spark plugs are an important component in a motor with an internal combustion chamber. After the ignition coil sends an electrical signal to the spark plugs, the spark plugs transmit a signal to the combustion chamber. In such a way that the fuel and air mixture is ignited with a spark from the spark plug. If the spark plug fails to operate properly, then the engine performance will be greatly reduced and the peak can make the engine limp.

Ignition Coil

This section is also only for gasoline engines. The ignition coil in the ignition system is an important part of the engine which converts 12-volt battery voltage to 20,000 volts. This voltage is needed to generate a spark jump on the spark plug. Which is then used to burn the fuel and air mixture in the engine. If the ignition coil is damaged, then the vehicle may not be able to accelerate and of course, the power loss will inevitably occur.

Oxygen Sensor Not Working

When the exhaust gases leave the engine, the amount of gas leaving the engine is measured by the oxygen sensor. The ECM then uses this information to describe the time it takes for the fuel-air mixture to form. The oxygen sensor is located in the exhaust system line. This allows the engine timing and fuel injection system to do their job efficiently. The oxygen sensor supports fuel emission control. But if it doesn’t work properly, it can cause inaccuracies in sending information about the fuel-air mixture ratio to the ECM. This will cause the engine to begin to experience a decline in performance and at its peak will result in a negative impact on the environment.

Causes of Car Loss of Power
Bad oxygen sensor.

Broken Injector – Causes of Car Loss of Power

A fuel injector is a very important component in a car. They are placed inside the fuel system. And their main task is to spray fuel into the engine. The computer on the engine controls the fuel injector and the timing and shape of the fuel spray into the engine. In this way, the machine can perform optimally. If the fuel injector is damaged or not functioning properly, then the engine cannot generate the amount of power required by the vehicle. You can assume that all engine performance problems are down to the injectors because the injectors are a major part of the fuel system.
