Hi, I cleaned the throttle body on my 2010 TSX. Idle is now high and I'm getting P0507. I know that the ECM has to relearn the closed throttle position.

Is there a procedure to reset everything - key om/off, accelerator, etc?

Thanks

Yes just read the service Manuel .

Idle Control System
ECM/PCM Idle Learn Procedure
The idle learn procedure must be done so the ECM/PCM can learn the engine idle characteristics.

Do the idle learn procedure whenever you do any of these actions:
• Replace the ECM/PCM.
• Reset the ECM/PCM.
• Update the ECM/PCM.
• Replace or clean the throttle body.
• When the engine or transmission is disassembled.
NOTE: Clearing the DTCs with the HDS does not require you to do the idle learn procedure.

1. Make sure all electrical items (A/C, audio, lights, etc.) are off.
2. Reset the ECM/PCM with the HDS.
3. Turn the ignition switch toON (II), and wait 2 seconds.
4. Start the engine. Hold the engine speed at 3,000 rpm without load(A/T in Por N, M/T in neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194 °F (90 °C).
5. Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes.
6. Verify on the HDS data list that the idle learn procedure is complete
