I popped this code 2 months 2 weeks ago.
Was a week after my 105k km (~65k miles) oil change. Popped the hood to check o2 sensor, realized was missing my oil fill cap. Bought a new cap, then cleared ecu by popping battery for 20 minutes while I cleaned off the excess oil about my engine compartment.
Since then, haven't had any codes pop with ~3k miles driven.
Now would this example be the same situation for you? No knowledge, just passing along my experience.
