Just the other day I started my 2012 Civic EX and got a "Check Emission System" on the i-MID display. I also noticed that the check engine light is also on.

I hooked up my Laptop, ran a diagnostic and it showed a P0128 error coded. This code came up as a "Coolant Thermostat below regulating temp"
There are no other codes and no pending codes.

I cleared the code and then drove the car till it fully warmed up and then parked it. The warning is still off. How many drive cycles do I need to see if the warning returns?

I'll plug in my laptop after lunch and see if there are any code pendings.
