Hi,
Diagnostic Code: P1516
Tests/Procedures:
1. Clear code and start engine, if code does not reset stroke accelerator pedal to rev engine and see if code resets.
2.
If code sets, lab scope the 2 Throttle Position Sensor (TPS) circuits
on the throttle body (Purple wire pin D and Dark Green wire pin A) with a
lab scope looking for glitches or drop outs as open the throttle plate.
If there is no voltage check for the wire being shorted to ground.
3. Verify the Black and Black/White wires are good grounds and the Light Blue/Black and Gray wires have 5 volts.
4. Replace throttle body assembly if wiring is OK but sensors have glitch or drop out.
Potential Causes:
Accelerator Pedal Position (APP) Sensor
Throttle Body Module
Wiring Harness
Diagostic Code: P2101
Throttle Actuator Control Motor Position PerformancePossible Causes
Throttle body connector is damaged (check pins for damage, and for moisture)
TAC motor control 1 or 2 circuit is open or shorted to ground
TAC motor control 1 or 2 circuit is shorted to voltage
Throttle body assembly has failed

If there is no driveability issues, i would recommend you to take the car to the dealer as there were certain bulletins issued when the check engine light would throw these error's due to software glitch.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
