the readiness monitors should all be ready as long as you have not cleared dtcs, disconnected your battery, or there is a pending dtc and it is monitoring the data to see if a dtc should be set.
heres how to "try" and get the monitors "ready".
start with 1/2 to 3/4 of a tank of gas. evap monitors wont run with a full tank or almost empty tank
Step 1. The vehicle must have sit for 8 hours,without a start. This is required for the EVAP Monitor in some makes, and especially true for some Fords that include a 6 to 8 hour cold soak as part of the EVAP Monitor enabling criteria.
Step 2.Warm the engine to normal operating temperature before driving it.
Step 3. Drive the vehicle for 10 minutes at highway speeds.
Step 4. Drive the vehicle for 20 minutes in stop and go traffic with at least four idle periods.
Do not turn the ignition off during the cycle. You can connect a scan tool and take a
passenger along to watch the Monitor test status display to inform you when all the
Monitors have run to Completion.
