Some states have vehicle emission inspection programs which include OBD (On Board Diagnostics) checks. The OBD system monitors the operation of the emission control system.
The OBD system determines that a problem exists somewhere in the emission control system. Your vehicle may not pass the I/ M test and may need to be repaired. Contact your Toyota dealer to service the vehicle.
Also, depending on your driving habits, the readiness codes may not be completely set.
The error code in the OBD system will not be cleared unless the vehicle is driven 40 or more times.
Contact your Toyota dealer to prepare the vehicle for re-testing.
