I am looking at Tire Rack for winter tires and rims with the TPMs attached.
Will the computer recognize the new TPMs automatically or does it need to be reprogrammed?

 

almost positive it will have to be re-trained. I had to do it for my 06 expy. I am pretty certain the instructions are the same for the f150. Here are the instructions a member shared. I used an old 10" subwoofer I had laying around for the magnet. It worked, but had to do it twice.

Principles of Operation

The tire pressure monitoring system (TPMS) monitors the air pressure of all four regular road tires. The wheel-mounted tire pressure sensors transmit via radio frequency (RF) signals, to the TPMS module (integral to the vehicle security module (VSM)), using the valve stem as an antenna. These transmissions are sent approximately every 60 seconds when the vehicle speed exceeds 32 km/h (20 mph). The TPMS module (integral to VSM), compares each tire pressure sensor transmission against a low-pressure limit. If the module determines that the tire pressure has fallen below this limit, the module communicates this on the controller area network (CAN) to the instrument cluster, illuminates the TPMS indicator and displays the appropriate message center message.

The system is not affected by wheel and tire rotation.

Sensor Training (Reset Procedure)

NOTE: The tire pressure monitoring system is not affected by wheel and tire rotation.

NOTE: The tire pressure sensor training procedure must be done on a single vehicle, in an area without radio frequency (RF) noise.

RF noise is generated by electrical motor and appliance operation, cellular telephones and remote transmitters, power inverters and portable entertainment equipment.


1.Turn the ignition switch to the OFF position.
2.Turn the ignition switch from the OFF position to the RUN position three times, ending in the RUN position. Do not wait more than one minute between each key cycle.
3.Press and release the brake pedal.
4.Turn the ignition switch to the OFF position.
5.Turn the ignition switch from the OFF position to the RUN position three times, ending in the RUN position. Do not wait more than one minute between each key cycle.

6.The horn will sound once and the TPMS indicator will flash if train mode has been entered successfully. If equipped, the message center displays "TRAIN LF TIRE", place the magnet on the valve stem of the LF tire pressure sensor. The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the TPMS module.
7.Within two minutes after the horn sounds, place the magnet on the valve stem of the RF tire pressure sensor.
NOTE: If the VSM (TPMS module integral to VSM) does not recognize any one of the four tire pressure sensors during the tire training procedure, the horn will sound twice and the message center (if equipped) will display " TIRE NOT TRAINED REPEAT" and the procedure must be repeated.

8.Repeat Step 7 for the RR and LR tires.
When the tire training procedure is complete, the horn will sound once and the message center (if equipped) will display " TIRE TRAINING MODE COMPLETE". <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

 

Thanks. I'll give it a try.

 

Thanks for these steps mtrondeo! I just picked up a nice F150 with 24" wheels and found that after installing new sensors at a cost of $500, the system light was still on. After some choice words, I decided to seek free help here. God bless you brother!

Your absolutely welcome and glad it worked for you. I can only take the credit for re-posting as another member had put it up here a while ago and I can not remember who. But again, glad it worked, Mike.
