Why is a Scan Tool Throttle Relearn Necessary?
After replacing a throttle body, disconnecting the battery, or clearing certain error codes, your Dodge’s computer might lose its understanding of the throttle position. This can lead to issues like rough idling, poor acceleration, and even stalling. A scan tool throttle relearn procedure recalibrates the throttle position sensor (TPS) and the electronic throttle control (ETC) system, ensuring they communicate effectively with the engine control module (ECM).

How to Perform a Scan Tool Throttle Relearn on a Dodge
While the specific steps can vary slightly depending on the year and model of your Dodge, the general process is as follows:
- Connect a compatible scan tool: Ensure your scan tool supports throttle relearn functionality for Dodge vehicles.
- Turn the ignition key to the ON position: Do not start the engine.
- Access the throttle relearn function: Navigate through the scan tool’s menu to find the throttle relearn procedure. This is usually found under “special functions” or “relearns.”
- Follow the on-screen prompts: The scan tool will guide you through the process, which typically involves turning the ignition off, waiting a specific time, and then turning it back on.

Troubleshooting Common Issues
- Scan tool won’t connect: Verify the OBD-II port is clean and undamaged and ensure the scan tool is compatible with your Dodge’s model year.
- Relearn procedure fails: Double-check that you’re following the correct steps for your specific vehicle. Sometimes, a low battery voltage can interfere with the process.
- Symptoms persist after relearn: If you still experience issues after performing the relearn, there might be a separate mechanical or electrical problem that requires further diagnosis. Contact a qualified technician for assistance.
Understanding the Role of the TPS and ETC
The TPS monitors the position of the throttle plate and sends this information to the ECM. The ECM uses this data to control fuel delivery and ignition timing. The ETC system uses an electric motor to control the throttle plate, eliminating the need for a traditional mechanical cable. A scan tool relearn ensures these components work harmoniously.

Why Choose a Professional Scan Tool?
While some generic scan tools claim to offer throttle relearn capabilities, investing in a professional-grade scan tool designed specifically for Dodge vehicles is highly recommended. These tools often provide more accurate readings, faster processing, and access to more advanced features. For a reliable jeep scan tool, look no further than CARW Workshop.
How Long Does a Throttle Relearn Take?
Typically, the relearn procedure itself only takes a few minutes. However, it’s crucial to follow the waiting periods specified by the scan tool and your vehicle’s service manual.
“A proper throttle relearn is essential for optimal engine performance after certain repairs or maintenance procedures,” says John Miller, ASE Certified Master Technician. “Using the right scan tool and following the correct procedure can save you headaches down the road.”

- What happens if I don’t perform a throttle relearn? You may experience drivability issues like rough idling, poor acceleration, and reduced fuel economy.
- Is a scan tool throttle relearn the same as a TPS reset? While related, a throttle relearn involves recalibrating the entire ETC system, not just the TPS.
- What if my check engine light stays on after the relearn? This indicates another issue; further diagnosis is required.
- Can I damage my car by performing a throttle relearn incorrectly? Unlikely, but it’s important to follow the correct procedure to avoid potential issues.
