Code P2272 on a Ford Freestyle?

Code P2272 is a code indicating the O2 sensor post catalyst on bank 2 is staying lean all the time. This is due to a defective sensor or an exhaust leak in front of the sensor in most cases. This will cause the vehicle to fail emission testing.

I took my car in for an emission test, but it couldn't be tested because the OBD system was not ready. What does that mean?

Before an OBD test or auto diagnostics can be done, most of the emission control system monitors have to complete their checks of the emission control equipment. Depending on the age of your vehicle, if one or two monitors have not yet completed their checks, the vehicle is not ready for an OBD test. If this happens, you will need to drive your vehicle further to allow these monitors to finish testing the equipment. The amount and type of driving needed varies according to the vehicle.

Lighter fuse

Yes.
The OBD connector for the scanner is powered by the same circuit as the cig lighter. If the fuse is blown, the testing facility can not access the computer on the car.

Trouble code po420?

that is the code for the catalytic convertor. it is either bad or not working at optimal levels. In most cases this in not such a big deal unless you live in a state that does emission testing buy pug in and not tail pipe emissions. Most states now use a quick OBD II plug-in test to check emissions compliance on 1996 and newer vehicles. The plug-in test is faster, easier and cheaper to do than a loaded mode tailpipe emissions test on a road simulator or dynamo-meter. The rules in most states say to pass the OBD II plug-in test, the vehicle (1) must have a fully-functional OBD II system (Check Engine lamp works and the diagnostic connector communicated with the engine computer), that the Check Engine light must be off and that there are no current codes in the computer's memory. If this is the case than you're going to have to replace the converter.

Did not pass state inspection (vehicle)

First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.

Emissions test

Most of the Smog testers need to use the speedometer for testing since they have to test your vehicle emissions at 15mpg, 25 mph, etc. So you will likely need to get that fixed before your testing
