Mary found a tech bulletin that listed a no-cost way to recalibrate the pedal to the throttle body:

Syncing or Recalibrating the Gas Pedal (Throttle Position Sensor) on a Dodge After Replacement
After replacing the gas pedal (which houses the Throttle Position Sensor or TPS) on a Dodge, you may need to recalibrate it to ensure proper throttle response and engine performance.
Here are a few common methods you can try, although it's always recommended to consult your vehicle's specific repair manual for the most accurate procedure:
Method 1: Accelerator Pedal Position Sensor Recalibration (Manual Method)
This method involves a specific sequence of steps using the ignition key and accelerator pedal. The steps include turning the ignition to the "ON" position (without starting the engine), slowly depressing and releasing the accelerator pedal multiple times, turning the ignition off, waiting, and then starting the engine. The engine should be allowed to idle afterward for the engine control module (ECM) to relearn the throttle position.
Method 2: Battery Disconnect and Reconnect
Another approach is to disconnect the negative battery cable for a period of time to allow the system to reset. After reconnecting the cable, turn the ignition to the "ON" position without starting the engine to allow the ECU to initialize, and then start the engine and let it idle.
Method 3: Professional Scan Tool (Required for Newer Dodge Models)
For newer Dodge models (typically 2009-2010 and later), a professional scan tool is usually necessary to perform the Electronic Throttle Control (ETC) learn procedure. This can be done by a mechanic or dealership using diagnostic equipment like a WiTech scan tool.
Important Notes:
- Symptoms that might indicate a need for recalibration include unstable idle or poor throttle response.
- While not always required, the relearn procedure is recommended if you experience these symptoms after replacing the pedal.
- Some older models may also require a scan tool. Refer to your vehicle's manual or consult a professional if you are unsure.
- If issues persist after trying manual methods, it's best to seek professional diagnosis and repair.
