Ram 1500 is a popular full-size pickup truck model manufactured by Ram Trucks. We bought the vehicle due to its popularity and we were very happy until the service electronic throttle control Ram 1500 light appeared and then disappeared in a few seconds.
While we faced no drivability issues, we still wondered what could cause the problem as there could be underlying issues unaddressed. And we were right to figure out that issues like throttle body malfunction, TPS, APP sensor problems, or wiring mismatches can cause this. Let’s dive into it!
What Does “Service Electronic Throttle Control” Mean?
The Electronic Throttle Control (ETC) system, also known as drive-by-wire or throttle-by-wire, is responsible for controlling the engine’s throttle electronically.
While traditional vehicles use mechanical linkage to link the accelerator pedal and the throttle body, modern vehicles like the Ram 1500 use the total ETC system with electronic sensors and actuators.
The “Service Electronic Throttle Control” message is a warning indication that appears on your Ram 1500 when there are any issues in the Electronic Throttle Control (ETC) system.
If your Ram 1500 is showing this message, this means that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an issue with the ETC system.
Potential Reasons For The “Service Electronic Throttle Control” Message
There can be various reasons why you are getting the warning in your Ram 1500, but a few mentionable causes that we have found are:
- Throttle Body Malfunction: The electronic throttle body malfunction is one of the prior reasons why your Ram 1500 may be showing the error message. Oftentimes, the throttle body gets stuck, fails to respond, and doesn’t move properly. Thus, it gives a signal to the ETC about the malfunction and you get the warning.
- Sensor Issues: As the ETC mainly deals with sensors, any problem in the Throttle Position Sensor (TPS) or the Accelerator Pedal Position Sensor (APP sensor) may show a warning message. It can be due to incorrect throttle position readings and a lack of engine response.
- Sensor Calibration Errors: Once again, if the sensors included in the linkage fails to calibrate properly, the error message may occur. This is mostly seen when you are repairing your vehicle.
- Connection Problems: If the sensor or actuator linkage has some faulty or loose connections in between, the ECM/PCM can disrupt communication and show the warning message for you to take a look inside.
- ECM/PCM Malfunction: The biggest problem arises when the ECM/PCM itself has any problem in the control module. This can also trigger a warning message.
- Accelerator Pedal Position Sensor (APP Sensor) Problem: This issue is mostly common behind the error message occurrence cases that we have dealt with. The accelerator pedal position sensor may not be functioning correctly, which sends disrupted signals to the ECM/PCM, making the warning.
How To Resolve The Issue In Ram 1500?
If you are experiencing the “Service Electronic Throttle Control” message in your Ram 1500, here are some possible fixes that you could explore:
- Check For Error Codes: If your Ram 1500 has a diagnostic scanner, it will show you error codes when it encounters any issue. Thus, from reading the code, you will know where the exact problem is and how you can fix that.
- Inspect Throttle Body: As the throttle body issues may create the error message, you need to check for possible dirt accumulation in there. You can try cleaning the throttle body or repairing the areas of problem.
- Verify Connections: As we mentioned, improper wiring or connections may induce the problem. Therefore, you need to inspect every connection in the ETC system and make sure that the connections are secure and not damaged. If you notice any loose or corroded connections, take attempts to repair them promptly.
- Check Sensors: The Throttle Position Sensor (TPS) and Accelerator Pedal Position Sensor (APP Sensor) are the main areas for inspection in this case. There might be faulty signals that may make the message occur. If you notice anything different than usual, try to make a replacement.
- Check The Voltage: Some users have experienced this error occurring due to a low system voltage. If you’re seeing less than ~14VDC across the battery with a voltmeter, you might need to change your battery. Sometimes, old batteries create a fuss like this.
- Reset The Pedal Commander: If you have a pedal commander installed, the error message might be coming from this. So, you need to clear the codes and get new codes to make it all good again.
How To Reset The Electronic Throttle Control Light?
The ETC light occurs whenever you have any issues in your vehicle. So, the first thing to do is to address the potential issues that we have mentioned above. Then, you can reset the light if you think that the matter is already handled.
But if you need to do it promptly, you can also identify the error codes using a diagnostic scanner and reset the ETC light. This will also reset the vehicle’s ECM or PCM. You can use an OBD-II scanner to read and clear the codes. If you don’t have a mechanic nearby, you can note the codes down for further inspection.
After noting down the codes, you need to clear them out. Now usually turning the vehicle’s ignition to the “ON” position without starting the engine, and selecting the “Clear Codes” option on the scanner resolves it all. But if you are using a different diagnostic scanner, it might require some other steps.
You can also try disconnecting the battery for a few minutes and reconnecting it to reset the ETC light. Now, if you have already settled the issues but the light is still on, you might need to check further to ensure everything is fine.
More To Learn About The Problem
The cost to fix the electronic throttle control on a Ram 1500 can range from $200 to $500 for minor repairs, but more significant problems could cost over $500.
To manually reset the “Service Electronic Throttle Control” message, start by turning off the engine. Wait for a few minutes, then restart the vehicle. If the issue persists, use a scanner to clear any stored error codes.
Driving with the electronic throttle control light on is not advised. It indicates a potential issue with the throttle system that could affect your vehicle’s performance and safety. So, try to solve the issues to have a safe drive.
The electronic throttle control sensor is generally found near the throttle body, linked to the accelerator pedal. The exact location may differ depending on the Ram 1500’s year and engine type.

Bottom Line
The warning message service electronic throttle control Ram 1500 may seem frustrating, but good thing that it has a very low chance of reappearing if you solve the issue. However, if the issue is caused by factors like wiring problems, you need to pay a visit to the mechanic instead of trying to fix it on your own.
