ECM/PCM Idle Learn Procedure: Notes

WARNING: This page is about a different car, the 2008 Acura TL and 2007 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

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 procedure:

Replace the throttle body
Clean the throttle body
Replace ECM/PCM
Update ECM/PCM
Reset ECM/PCM
When the engine or transmission is disassembled
NOTE: Clearing DTCs with the HDS does not require you to do the idle learn procedure.
