Did a mechanic replace it?

Are you sure it's the right part?

Have you cleared the codes and then does it still pop back up?

Throttle body learn without scan tool.
Without Scan Tool-Learn

Important:
Do NOT perform the Without Scan Tool-Learn procedure if DTCs are set. Refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: A L L Diagnostic Trouble Codes ( DTC )\Testing and Inspection\Diagnostic Trouble Code Descriptions).

  1. The engine speed is between 450-4,000 RPM.
  2. The manifold absolute pressure (MAP) is greater than 5 kPa.
  3. The mass air flow (MAF) is greater than 2 g/s.
  4. The ignition 1 voltage is greater than 10 volts.
  5. Start and idle the engine in Park for 3 minutes.
  6. With a scan tool, monitor desired and actual RPM.
  7. The ECM will start to learn the new idle cells and Desired RPM should start to decrease.
  8. Ignition OFF for 60 seconds.
  9. Start and idle the engine in Park for 3 minutes.
Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.

  1. After the 3 minute run time the engine should be idling normal.
¤If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles.
  1. After the drive cycle, the engine should be idling normally.
¤If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6.
  1. Once the engine speed has returned to normal, clear DTCs.

I fixed your title so it says something more specific. Everyone coming here with car troubles wants help, so it's better to start with your problem. Good luck! ;)
