today our Acura 3.2TL (2000 model) got the code P01456 (or P1456).


A quick google search found that is most likely the 'EVAP Emission Control System Leak Detected (Fuel Tank System).' and the cause is a loose gas cap.

Checked the gas cap and found it slightly loose. reset the code to see if it would happen again.


However, now we are getting a flashing "maintenance required" light?

how do you clear that?

btw... it's not time for scheduled maintenace yet.
