hi im new to the site but not to fords i recently purchased an 07 expy w 50k miles and it needed tires. so at the tire shop we get down to the last rim and of course some idiot had previously patched the tire and in the process broke the holddown on the tpms sensor, and messed up the band so they ziptied it back in place . SO now i need to find a new sensor and band, ebay seems to be the place to go i can get 4 sensors for 40 bucks w/o bands my question is does the tpms need to be reprogrammed for the new sensor or does it just reset itsself ?? any info or a better idea on where i can get the band and sensor cheaper id appreciate it thanks: the part # is 6f2a-1a176-ae

 

Tire Pressure Monitoring System (TPMS) Sensor Training


Tire Pressure Monitoring System (TPMS) Sensor Training



NOTE: If the vehicle has been stationary for more than 30 minutes, the sensors will go into a "sleep mode" to conserve battery power. It will be necessary to wake them up so they will transmit the latest tire pressure information to the smart junction box (SJB). For additional information, refer to Tire Pressure Monitoring System (TPMS) Sensor Activation. See: Tire Monitoring System\Testing and Inspection\Monitors, Trips, Drive Cycles and Readiness Codes

NOTE: The tire pressure sensor training procedure must be done on a single vehicle, in an area without radio frequency noise and at least 1 m (3 ft) away from other vehicles equipped with tire pressure monitoring system (TPMS).

Radio frequency noise is generated by electrical motors and appliance operation, cellular telephones, remote transmitters, power inverters and portable entertainment equipment.

NOTE: If a sensor does not respond to the activation tool, attempt to activate the same sensor with the activation tool. If the sensor still does not respond, move the vehicle to rotate the wheels at least 1/4 of a turn and attempt to activate the same sensor again.

NOTE: The SJB has a 2-minute time limit between sensor responses. If the SJB does not recognize any 1 of the 4 tire pressure sensors during this time limit, the horn will sound twice and the message center (if equipped) will display TIRE NOT TRAINED REPEAT and the entire procedure must be repeated.

NOTE: For vehicles with different front and rear tire pressures (such as the E-Series and certain F-Series), the tire pressure sensors must be trained following a tire rotation. Failure to train the sensors will cause the TPMS indicator to illuminate. For vehicles with the same tire pressure for front and rear tires, tire rotation will not affect the system.

1. Turn the ignition switch to the OFF position, then press and release the brake pedal.
2. Cycle the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position.
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 3 times, ending in the RUN position.

o The horn will sound once and the TPMS indicator will flash if the training mode has been entered successfully. If equipped, the message center will display TRAIN LF TIRE.

6. NOTE: It may take up to 6 seconds to activate a tire pressure sensor. During this time, the activation tool must remain in place 180 degrees from the valve stem. Place the activation tool on the LF tire sidewall opposite (180 degrees) from the valve stem. Press and release the test button on the special tool. The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the SJB.



7. Within 2 minutes of the horn sounding, place the activation tool on the RF tire sidewall opposite (180 degrees) from the valve stem and press and release the test button to train the RF tire pressure sensor.



8. NOTE: Do not wait more than 2 minutes between training each sensor or the SJB will time out and the entire procedure must be repeated. Repeat Step 7 for the RR and LR tires. The procedure is completed after the last tire has been trained. When the training procedure is complete, the message center (if equipped) will display TIRE TRAINING COMPLETE. For vehicles not equipped with a message center, successful completion of the training procedure will be verified by turning the ignition switch to the OFF position without the horn sounding. If the horn sounds twice when the switch is turned to the OFF position, the training procedure was not successful.
9. Using the scan tool, locate the updated TPMS sensor IDs trained to the SJB and document them on the applicable warranty claim.
10. NOTE: This step is required to clear DTC C2780, cause the SJB to exit the manufacturing mode and to make sure there are no other concerns with a newly programmed SJB. If the sensors are being trained due to the installation of a new SJB, clear any DTCs and perform the SJB on-demand self test.
