If this happened after a period of time in which the FJ was parked, be sure to check your fuel cap. Remove it and re-install it.
The Emissions control system does an evap control system self-check after the fuel tank cools off at night. This also explains the strange hummm of a vacuum pump running if you are ever sweeping the garage about 5 hours after getting home. 
Good luck |
Good catch! I've totally forgotten about that.
