PCM Idle Learn Procedure: Notes

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

The idle learn procedure must be done so the PCM can learn the engine idle characteristics.

Do the idle learn procedure whenever you do any of these actions:

Replace the PCM
Reset the PCM
Update the PCM
Replace or clean the throttle body
Disassemble the engine or the transmission
NOTE: Erasing DTCs with the HDS does not require you to do the idle learn procedure.
