How to Fix Electronic Throttle Control Dodge Ram 1500

The electronic throttle control in the Dodge Ram 1500 is a feature that uses electronic signals to control the vehicle’s speed and acceleration. This technology is also known as a drive-by-wire system because of its design.

Electronic throttle control works with a combination of PCM, accelerator pedal module, throttle position sensor, throttle body, and valve. Therefore, if any of the above components is damaged or faulty, the electronic throttle control will malfunction.

As a result, some common problems, such as an unresponsive acceleration pedal, check engine warning light, rough acceleration, and engine stalling problems, occur. To fix the electronic throttle control system, you should identify the problematic part first and then fix it.

In this article, I have discussed the symptoms, main causes, and solutions of Dodge Ram 1500 electronic throttle control problems.

Symptoms of Electronic Throttle Control Problems in Ram 1500

Some common symptoms of electronic throttle control problems are:

  • Unresponsive gas pedal
  • Engine stalling
  • Service electronic throttle control warning light
  • Slow throttle response
  • Decreased engine power
  • Poor fuel economy
  • Jerking or vibration during acceleration

The first sign is an unresponsive acceleration pedal when electronic throttle control malfunctions. When the throttle pedal is unresponsive, it becomes difficult for a driver to control the vehicle’s speed. Driving on high-traffic roads becomes dangerous in this situation.

Another major sign of throttle body problems is the service electronic throttle control warning light. The electronic throttle control system works with the PCM, and its communication is done using several electronic signals. When the PCM finds mismatches between signals or problems in the electronic throttle control (ETC), it triggers the warning light.

However, rough acceleration, engine stalling, and a check engine light are also related to electronic throttle control problems. When you experience throttle problems, inspect its main causes to fix them properly.

Causes of Electronic Throttle Control Problems

The major causes of electronic throttle control problems are:

1. Damaged Electronic Motor

The electronic motor is the main component of the electronic throttle control system. When the motor fails to work properly, the ETC system fails to control the throttle valve, too. ETC sends signals to the ECM and helps to determine the amount of air-fuel flow into the engine.

Using the signals, the ECM sends commands to the electronic motor and controls the throttle valve open-close ratios. A damaged electronic motor causes the throttle valve to get stuck, which reduces engine performance.

2. Faulty Throttle Position Sensor

The throttle position sensor sends important signals to the ETC, which adjusts the throttle position using the signals and ensures optimum performance. However, a faulty throttle position sensor provides inaccurate signals to the ETC, which fails to manage the throttle positions correctly, and vehicle performance decreases.

To fix the problem, you should replace the faulty throttle position sensor. However, before replacing it, you must test it to see whether it is bad. A multimeter will be used to test the throttle position sensor.

Connect the multimeter cable properly to both throttle position sensor wires, connect the multimeter cables to the throttle position sensor terminals, and take the voltmeter readings. Check the voltage reading on the multimeter. A properly working TPS voltage should be around 5 volts.

3. Wiring Problem

Electronic throttle problems, especially the service electronic throttle warning light, are illuminated when there is a wiring issue. Proper wiring between the accelerator pedal, ETC system, and the throttle body is essential.

The performance of these components depends on the electricity supply. The ECT also receives and sends signals through the wires. So, if any wire is damaged or broken, signals cannot transmit properly and cause malfunction.

4. Software Issues

The electronic throttle control system performs based on the software commands. If the software starts malfunctioning, it causes several throttle problems. Outdated software or if there is any glitch in the software, Software issues occur when there are any glitches in the software or it is outdated.

The most common signs of software malfunctions are error codes, reduced engine performance, and reduced fuel economy. Usually, updating the software to the latest version will fix the problem.

5. Dead Battery

If the vehicle battery is too old or dead, it cannot supply the necessary power to the ETC system. The battery’s corroded terminals also disrupt the signal transmission.

Dead batteries also cause vehicle starting issues. Replacing the battery is the only solution to fix all the problems.

How to Fix Electronic Throttle Control Dodge Ram 1500

The solution to the electronic throttle control problem in Ram 1500 depends on the problems that cause it. The problems mentioned above are also considered the common problem of the Ram 1500 ETC system.

So, if your Ram 1500 electronic throttle control system malfunctions and reduces the vehicle’s overall performance, check the main causes of ETC problems first. In most cases, the faulty throttle body actuator motor causes the ETC system to malfunction.

Take your vehicle to a mechanical shop and replace the faulty throttle body actuator motor to fix the ETC issues. However, here are some highlights that also help to fix the Ram 1500 electronic throttle control problems.

Reset the Service Electronic Throttle Control Light

Reset the Service ETC warning light by disconnecting and reconnecting the negative battery cables. The warning light sometimes appears on the Ram 1500 dashboard without any reason. Generally, disconnecting the battery will fix this issue.

But sometimes, the warning light indicates an actual electronic throttle control problem. In this case, check the ETC-related component to find out if it is faulty. When you find and fix the problem, the warning light will be gone.

Replace the Throttle Position Sensor

A faulty throttle position sensor is responsible for both the warning light and ETC other problems. I have already discussed above how to check throttle position sensor functionality. The normal voltage of TPS is around 5 volts.

If the voltage range is too high or too low, it indicates the sensor is not working correctly. In this situation, replace the throttle position sensor. Replacing the throttle position sensor costs around $200 to $220, including labor costs.

After installing a new throttle position sensor, reset the warning light. In this way, you will fix the electronic throttle control problems.

Fix the Wiring System

As the wiring system is an essential part of the vehicle, inspect the wiring visually. If any damage or broken wires are detected, replace them. If a proper connection between all the ETC-related components is established, the system will work normally.

Fix the Software Issues

Update your ECM software to the latest compatible version. Sometimes, the ECM system requires reprogramming. ECM malfunctions rarely cause electronic throttle control problems. However, if it happens, consult with a professional mechanic for proper solutions.

Replace the Dead Battery

As you know, a weak or dead battery causes several problems including the ETC problem, so replace it as soon as possible. Remember that Ram 1500 batteries prematurely die only if they are not maintained properly. So, take care of your vehicle battery properly and ensure regular vehicle maintenance.

The summary of the discussion is to check the components that are mainly causing electronic throttle control problems and then address the ETC problem in accordance with the findings.
