I will make an assumption here, we know what the root word means. This code was extracted from the computer by? What this is telling you one of 2 things: The Bank 2 oxygen sensor down stream of the catalytic converter (there are 2 converters, one for each bank of cylinders on the 4.6ltr engine) is bad and/or that the Bank 2 catalytic converter is no longer doing the job it was designed to do. Simply, Catalysts wear out. They are good for approx 100,000 miles (as required by Federal Law). Again, I assume that the reason the intake manifold was replaced was because it had a crack in one, or more, of the runners? (part that feeds the head of a manifold). It may have taken a while to find this as being the cause of why the car running incorrectly, maybe rough. This means, that during the time the car was being driven with the problem, the amount of unburned, or not within spec exhaust gases, coming off the side of the engine affected by the intake issue was higher than normal. This out of balance level of exhaust gases were being dumped into the converter on that side of the engine, thus causing the converter to have to run hotter, work harder, or even at the time the gas was being processed through, causing deposits to be formed in the converter, thus shortening it's life span. The Bank 1 side of the engine, apparently, did not have the issue and it's catalytic converter's life was not affected. I hope this makes sense to you.

bottom line is the U1262 is a communication failure between your scanner and a module
assuming you actually pulled the code from the PCM then you have lost communication with a different module like the ABS, DDM, LCM, RASM, HEC, PAM and any other module I can't think of right now
You need a detailed pinpoint test from a Ford service manual or aftermarket source like Alldata, Shop key or Mitchell on Demand
You could be dealing with over a 100 different test PER module
Obviously something we can't do on-line too easily
If you could at least identify which module you have lost communications with your dealer may, for a fee, copy the correct pinpoint test

If the speedometer itself is currently working fine, it may be that the Odometer and Trip-o-meter gears are broken. Lincolns OnLine have a large database of information regarding Town Cars from all years. This specific link will help you to order and replace the proper gears for your car.

The code is on a paper label attached to a large plastic box containing several wiring harnesses behind the driver side door panel. Posts about it being on the trunk hinge arms, behind trunk panels, on computer module, behind the fuse box, and 'you have to go to the dealer' are incorrect for this series of Town Cars. After you remove the panel (you do not need to disconnect any wires), you will see the box up near the rear view mirror. An example code (3/4) (1/2) (5/6) (9/0) (1/2). If you press the keypad buttons in this order,left to right, the door locks will operate in the manner described in your opwner's manual.
Do a search on door panel removal to learn how to remove the panel. There are some good posts on this topic - some even have pictures.
