This thread is to discuss resetting Ford TPMS.

SUBJECT VEHICLE: 2010 Ford Focus.

RELEARN PROCEDURE? Yes, directions follow.

SPECIAL TOOLS NEEDED? Yes, TPMS Activation Tool (P/N 204-363).

The tire pressure monitoring system (TPMS) on the 2010 Ford Focus monitors the air pressure in the four road tires with wheel-mounted tire pressure sensors.

The sensors transmit radio frequency signals to the smart junction box (SJB) every 60 seconds when the vehicle speed exceeds 20 mph. If the vehicle is stationary for more than 30 minutes, the sensor will enter into a sleep mode and stop transmitting.

Each tire pressure sensor transmission is compared against a low-pressure limit (the pressure listed on the vehicle certification label minus 25%, about 6 psi to 9 psi). If it is determined that the tire pressure has fallen below this limit, the SJB sends a message to the instrument cluster, which then illuminates the low pressure warning indicator and displays the appropriate message.

To remove an old sensor, follow these steps.

1. Remove the wheel and tire. NOTE: The valve stem is connected to the TPMS sensor. Do not pull the valve stem from the wheel, or damage to the sensor will occur.

2. Remove the valve stem core and fully deflate all air from the tire.

3. Remove the tire from the wheel following the tire manufacturer’s directions.

4. Remove the TPMS sensor from the valve in the following sequence (see Figure 1).

a. Using a T10 Torx, remove the valve stem-to-TPMS sensor screw.

b. Carefully and firmly pull the sensor straight down and separate it from the valve stem. NOTE: A new valve stem must be installed whenever a new tire or wheel is installed.

5. Using a suitable valve stem puller and a wood block, remove the valve stem from the wheel.

6. If the TPMS sensor is being reused, inspect the TPMS sensor for damage and install new parts as necessary.

To install a new sensor, follow the next step. NOTE: To prevent TPMS sensor and valve stem damage, the valve stem must be installed onto the TPMS sensor and then installed into the wheel as an assembly.

1. Install a new valve stem onto the TPMS sensor, tightening the valve stem-to-TPMS sensor screw to 13 in.-lbs. NOTE: it is important to pull the valve stem and TPMS sensor assembly through the wheel rim hole in a direction parallel to the valve stem hole axis. If the assembly is pulled through at an angle, damage to the valve stem and sensor assembly may occur.

Basic training

Now it is time to train the new sensor. NOTE: TPMS Activation Tool (P/N 204-363) must be used.

1. Turn the ignition switch to the OFF position, then press and release the brake pedal.

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. NOTE: The horn will sound once and the tire pressure warning light will flash if train mode has been entered successfully.

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. NOTE: It may take up to six seconds to activate a tire pressure sensor. During this time, the activation tool must remain against the sidewall of the tire.

6. Place TPMS Activation Tool (204-363) on the left front tire sidewall at the tire valve stem. Press the test button on the activation tool. The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the SJB. NOTE: Do not wait more than two minutes between training each sensor. If the wait time is more than two minutes, the SJB will stop and the training procedure must be repeated from the beginning.

7. Within two minutes after the horn sounds, place the activation tool on the right front tire sidewall 180 degrees from the valve stem for strap and cradle type sensors, or at the valve stem for valve stem-mounted sensors. Repeat the procedure for the right rear and left rear tires.

8. When the tire 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 ignition is turned off, the training procedure was not successful
