Dodge Ram Acceleration Problems

So, as a Ram owner, it’s best to get familiar with the common causes of these issues. Continue reading to find out the primary causes of Dodge Ram acceleration issues and what you can do to make them better.

What Are the Common Causes of Dodge Ram Acceleration Problems?

The common causes of Dodge Ram acceleration problems include issues with the fuel systems or engine sensors. Sometimes, Sometimes, clogged air filters can cause issues too. If you don’t fix these problems on time, things could get even worse for the vehicle’s engine.

Compromised Fuel Delivery System

To a large extent, the primary reasons for Dodge Ram’s acceleration problems reside within the fuel delivery system. When your truck’s fuel pump malfunctions, it might fail to supply the engine with a consistent fuel flow. Thus, insufficient fuel flow restricts the engine’s ability to generate the necessary power, leading to sluggish acceleration.

Similarly, clogged fuel injectors can disrupt the precise mixture of air and fuel. This affects your engine’s efficiency and ability to generate power. As a result, your Dodge Ram loses power while driving.

Air Intake Problems

The air intake system provides your engine with the oxygen it needs to burn fuel. If the air filter gets dirty, it stops air from flowing well to the engine. As time goes on, this problem makes it so the fuel doesn’t burn all the way and the truck doesn’t speed up like it should when you press the gas.

Causes of Dodge Ram Acceleration Problems

Also, if the hoses that bring in air gets damaged, extra air that isn’t measured can get into the engine. This affects how much air and fuel enters your engine, which disrupts how fast your truck can go.

Transmission-related Issues

The transmission helps turn the engine’s power into moving the truck forward. Transmission problems include slipping gears, worn clutch plates, and low transmission fluid levels. These issues can cause delays in power delivery. So, the gears might not get the power it needs when you hit the gas.

In severe cases, the Dodge Ram might encounter abrupt gear changes or fail to promptly engage the appropriate gear, meaning the truck won’t speed up like it should.

Low Fuel Quality and Contamination

If you use low-quality fuel or accidentally let contaminants into your fuel tank, it can impact how your engine works. Bad fuel might not contain the additives that keeps the engine clean, so dirt can build up in there over time. Consequently, your Dodge truck bogs down when accelerating.

Ignition System Malfunctions

The vehicle ignition system kickstarts the combustion process in the engine. Thus, faulty, or malfunctioning spark plugs or ignition coils can result in weak sparks or misfires.

This causes inadequate combustion within your Dodge Ram’s engine. And sometimes, the engine might run all uneven because of this.

Damaged Engine Sensors

Modern vehicles depend on several sensors to monitor various engine functions. Malfunctioning engine sensors, such as the oxygen, mass air flow, throttle position, or coolant temperature sensor, can deliver inaccurate data to the electronic control module (ECM), which manages various engine functions.

Below are the Dodge Ram acceleration issues associated with faulty engine sensors:

  • Mass air flow sensor (MAF) problems: The mass airflow sensor measures the amount of air getting into the engine. More so, this sensor helps your engine control module determine the appropriate fuel and air ratio for combustion. If the MAF sensor becomes dirty or faulty, it can provide inaccurate readings, causing an imbalanced air-fuel mixture. This leads to Dodge Ram hesitation on acceleration.
  • Oxygen sensor (O2 Sensor) failure: The oxygen sensor monitors the quantity of oxygen in the exhaust emissions and helps regulate fuel mixture. If the O2 sensor malfunctions, it can supply inaccurate information to the engine control module. Consequently, this triggers inadequate fuel adjustment and diminishes acceleration performance.
  • Throttle position sensor (TPS) problems: Throttle position sensor transmits the throttle commands to the engine control module (ECM). In cases where the TPS malfunctions or sends incorrect signals, the ECM might fail to provide the necessary fuel for the intended acceleration level. As a result, your Ram might not speed up smoothly.
  • Coolant temperature sensor issues: A faulty coolant temperature sensor can also cause Dodge Ram acceleration issues. The faulty sensor may provide inaccurate temperature readings to the ECM. This leads to incorrect fuel mixture adjustments, either running the engine too rich or too lean. Eventually, this leads to poor combustion and reduced engine performance.

Exhaust System Obstructions

A restricted exhaust system, marked by issues such as a bad catalytic converter or a damaged exhaust pipe, can hinder the effective discharge of exhaust gasses from your vehicle’s engine. This creates back pressure that reduces your engine’s overall power. Consequently, the Ram truck may experience poor acceleration.

Exhaust System Obstructions

Similarly, the exhaust gas recirculation (EGR) system reintroduces a small portion of exhaust gases into the engine. This helps control emissions and regulate temperature when fuel burns. If the EGR valve becomes stuck open or closed, it can disrupt engine operation, leading to your truck’s sluggish acceleration.

Faulty Throttle Body

The throttle body regulates the quantity of air that enters your engine. As time passes, carbon deposits can accumulate, resulting in a dirty throttle body. Thus, a malfunctioning throttle body can cause delays in throttle reactions and disturb the engine’s balance between air and fuel. Then, this results in reduced Dodge Ram acceleration.

What Are the Effective Solutions to Fix Dodge Ram Acceleration Issues?

The effective solutions to fix Dodge Ram acceleration issues involve checking for engine trouble codes. Examining the fuel system and replacing the damaged component can resolve the issue. You can also inspect the air intake system and replace the air filter if clogged.

Here are the effective solutions to fix the acceleration problems of your Dodge Ram truck:

Review Engine Trouble Codes

When your truck has issues, these special codes can give you clues about what might be wrong. So, this helps you figure out exactly what’s causing the problem. Therefore, when your check engine light comes on, use an OBD-II scanner to read trouble codes for clues about the problem.

You can attach the scanner to the diagnostic port situated beneath the dashboard on the driver’s side. Most importantly, carefully follow the scanner’s guidelines to retrieve the trouble codes.

Conduct Exhaust System Repairs

Check the exhaust system closely for signs of damage, like rust, cracks. Replace a faulty catalytic converter, muffler, or exhaust pipe blocking the seamless flow of exhaust gasses or generating back pressure.

Furthermore, depending on your Dodge Ram model, consider cleaning or replacing exhaust gas recirculation valves to restore smooth acceleration.

Examine Transmission Components

Making sure your truck’s transmission stays in good shape remains crucial to make sure it speeds up smoothly. Start by checking how much transmission fluid there is and its overall condition.

If the fluid is insufficient, replenish it to the prescribed level. Should the fluid seem contaminated or discolored, contemplate changing both the transmission fluid and filter according to the manufacturer’s instructions.

Throttle Body Cleaning and Calibration

Consistently cleansing the throttle body using a suitable cleaner will eliminate any accumulated residue and restore unobstructed airflow. This, subsequently, contributes to sustaining a smooth throttle response.

More so, certain contemporary throttle bodies are electronically managed and demand calibration. Seek expert aid to accurately calibrate the throttle body for optimal performance.

Inspect the Air Intake System

Locate the air filter housing, usually situated near the front of the engine bay. Take out the air filter and check for dirt, debris, or clogging. If the filter appears dirty or clogged, replace it with a new one to ensure optimal airflow to the engine. This simple yet effective fix can promote better acceleration.

Check the Fuel System

A well-functioning fuel system is crucial to unleash the full potential of your Dodge Ram’s acceleration. Start by regularly inspecting the fuel filter often positioned along your vehicle’s fuel line, between the fuel tank and the engine. If it’s dirty or obstructed, replace it to prevent constraints on fuel flow.

Next, closely look at the fuel pump for any signs of leakage or if it’s not working right. Also, check out the fuel injectors to make sure there’s nothing blocking them. If necessary, clean or replace the injectors to restore proper fuel dispersion. Consider changing your refueling station if you detect subpar fuel deposits in your fuel tank.

Thoroughly Inspect Engine Sensors

To inspect engine sensors, you can use a diagnostic scanner to check for any sensor-related trouble codes and replace malfunctioning sensors as necessary.

  • Throttle position sensor: To test the TPS, use a multimeter to check for smooth and consistent voltage changes as you slowly open and close the throttle. If you detect inconsistent readings, replace the TPS.
  • Mass airflow sensor: Remove the MAF sensor between the air filter and the intake manifold. Then, carefully clean it using MAF sensor cleaner. If cleaning doesn’t resolve the issue, consider replacing the MAF sensor.
  • Oxygen sensor: Replace damaged oxygen sensors to ensure the engine receives accurate data for proper fuel calibration.

Address Spark Plug Problems

Take out each spark plug and examine them for indications of deterioration, such as worn electrodes or an abundance of carbon deposits. Replace any malfunctioning spark plugs with fresh ones. Make sure to adhere to the manufacturer’s guidelines regarding the appropriate type and gap.
