Some 2008-10 Honda Odyssey minivans may come into your store with the MIL light on and trouble code P0128 (cooling system malfunction) stored in computer memory.
If the cooling system checks out and there are no symptoms related to the code it's probably bogus, Honda said, adding that the PCM is misinterpreting key input signals from several sensors during engine warm-up.
Reprogramming the module with updated software is the only viable solution.
Check with a Honda dealer for the application specifics.
