Goodyear Tire & Rubber Co. will report its third quarter results on Friday, Oct. 25, to be followed by an investor conference call at 9:30 a.m. ET.
SUBJECT VEHICLES: 2010 – 2018 Ford Econoline (E150-E450).
RELEARN PROCEDURE? No.
SPECIAL TOOLS NEEDED? Yes, TPMS activation tool (204-363).
The tire pressure monitoring system (TPMS) of the 2010-2018 Ford Econoline (E150-E450) monitors the air pressure in the 4 road tires with wheel-mounted tire pressure sensors. The sensors transmit radio frequency signals to the smart junction box (SJB) approximately every 60 seconds when the vehicle speed exceeds 20 mph (32 km/h). 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%, which will be about 6-9 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(s) in the message center (if equipped).
This vehicle may be equipped with one of two different kinds of sensors: a strap and cradle sensor or a valve-mounted sensor. In either case, the sensor cannot be seen unless the tire is removed. The valve stem’s appearance can be used to determine the type of sensor that is used in the wheel. The following 2 types of valve stems are used on wheels that are equipped with strap and cradle mounted sensors.
1) The valve has a rubber seal between the valve and the wheel with brass of a uniform diameter all the way down to the seal.
2) The valve is all metal and is attached to the wheel by a nut. Valve stems that are equipped with valve-mounted sensors have a rubber seal against the wheel, and an extra brass shoulder, larger in diameter and with no threads, that can only be seen when the valve cap is removed.
All tire pressure sensors are battery-operated. The strap and cradle sensors are mounted to metal brackets (called cradles) on the wheels inside the tires. The sensors are mounted 180 degrees from valve stem. The tire pressure sensor may be serviced separately, but the cradle and strap must be replaced together. The valve-mounted sensors are attached to the portion of the valve stem located inside the wheel with a T10 Torx screw. Under the following conditions, the TPMS may not function properly:
Tire pressure monitor warning indicators
NOTE: As ambient temperature decreases by 6 degrees Celsius (10 degrees Fahrenheit), tire pressure decreases 1 psi (7 kPa). Because tire pressures fluctuate with temperature changes, tire pressures must be set when tires are at outdoor ambient temperatures. Tire pressure may drop enough to be detected by the TPMS, which will activate the low pressure warning light.
When the tire pressure warning light comes on solid and message center displays “LOW TIRE PRESSURE,” check the air pressure of all tires and adjust to the specified cold pressure listed on the vehicle certification label (found on the driver’s door or door pillar).
Drive the vehicle at 20 mph (32 km/h) for at least 2 minutes. If the vehicle has been stationary for more than 30 minutes, the sensor will enter into a “sleep mode” and stop transmitting. Make sure the warning light goes off. If the warning light stays on, there is a malfunction in the TPMS. See the appropriate manufacturer service information. When the tire pressure warning light flashes for 70 seconds and then remains illuminated, after bulb-check has been performed and the message center displays warning messages, there is a malfunction in the TPMS. See the appropriate manufacturer service information.
TPMS reset procedures
NOTE: If the tire pressure sensor is replaced, it will need to be trained. If the vehicle has different front and rear tire pressures, the tire pressure has to be adjusted and the TPMS sensors has to be trained. If the vehicle has the same tire pressure on the front and rear tires, the TPMS is not affected by wheel and tire rotation.
When the tire pressure warning light comes on solid and the message center displays “LOW TIRE PRESSURE,” check the air pressure of all tires and adjust to the specified cold pressure listed on the vehicle certification label (found on the driver’s door or door pillar). Drive the vehicle at 20 mph (32 km/h) for at least 2 minutes. Ensure that the TPMS indicators go out. The TPMS sensor activation procedure may also be used to trigger a pressure sensor broadcast. See “Tire pressure sensor activation.” Ensure that the TPMS indicators go out.
Tire pressure sensor training
NOTE: In the following procedure, TPMS activation tool (204-363) must be used.
NOTE: The tire pressure sensor training procedure must be done on a single vehicle, in an area without radio frequency (RF) noise and at least 3 ft. (1 m) away from any other vehicle equipped with a TPMS. RF noise is generated by electrical motor and appliance operation, cellular telephones and remote transmitters, power inverters and portable entertainment equipment.
NOTE: A new tire pressure sensor is shipped in an OFF mode (or battery saver mode), and must be turned ON before it can be trained. To turn the sensor on, inflate the tire to the recommended inflation pressure and wait at least 2 minutes, then continue with the sensor training procedure.
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 3 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 the train mode has been entered successfully (if equipped, the message center displays “TRAIN LF TIRE”).
5) Turn the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position. Do not wait more than one minute between each key cycle.
NOTE: It may take up to 6 seconds to activate a tire pressure sensor. During this time, the activation tool must remain against the sidewall of the tire.
NOTE: If a sensor does not respond to the activation tool, attempt to activate the same sensor using 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: If the SJB does not recognize any one of the 4 tire pressure sensors during the 2 minute time limit for each sensor response, the horn will sound twice and the message center (if equipped) will display “TIRE NOT TRAINED REPEAT.” The training procedure must be repeated from the beginning.
6) Place TPMS activation tool (204-363) on the left front tire sidewall at the 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 2 minutes between training each sensor. If the wait time is more than 2 minutes the SJB will stop and the training procedure must be repeated from the beginning.
7) Within 2 minutes after the horn sounds, place the activation tool on the right front tire sidewall at the valve stem. Repeat the procedure for the right rear and left rear tires, in that order.
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 ignition is turned off, the training procedure was not successful.
Tire pressure sensor activation
1) Turn the ignition switch to the ON position.
2) Place the activation tool on the left front tire sidewall at the valve stem.
NOTE: A green light will flash and a beep will sound on the activation tool for each successful TPMS sensor response.
3) Press the test button on the activation tool to activate the TPMS sensor. For best results, activate each sensor twice.
NOTE: If, after adjusting tire pressures and activating sensors, the tire pressure warning light is still illuminated, there is a malfunction in the TPMS system. See the appropriate manufacturer service information.
4) Perform the activation procedure for each remaining tire.
CAUTION: The tire should be demounted from the wheel using the tire changer manufacturer’s instructions. Use the following information to avoid damage during the demounting/mounting procedures.
CAUTION: The tire and wheel must always be correctly matched. It is very important to determine the size of each component before any assembly operations commence. Failure to adhere to these instructions can result in an explosive separation and cause serious bodily injury or death.
CAUTION: Use only wheels and wheel nuts that have been designed for the current model year. Tire pressure sensors are not designed to be used with aftermarket wheels. Aftermarket wheels or wheel nuts may not fit or function correctly, and can cause personal injury or damage to the vehicle. A wheel and tire assembly equipped with tire pressure sensor will have the following verbiage stamped or cast on the wheel: “Sensor May Be Inside.”
CAUTION: Tighten wheel nuts in a star pattern. Failure to follow tightening specifications may result in high brake disc runout, serious injury or death.
NOTE: The use of run-flat tires (tires with steel body cord plies in the tire sidewall) when the vehicle is not originally equipped is not recommended, as it may cause the TPMS to malfunction.
NOTE: If possible, use a digital tire gauge (Ford Part #204-354, for example) any time tire pressures are measured to be sure that accurate values are obtained. Ford recommends the use of a digital or dial type tire pressure gauge rather than a stick type gauge for increased accuracy.
Tire pressure sensor
NOTE: If the vehicle is equipped with the strap or cradle type TPMS sensor, see “Tire pressure Sensor in the Ford Econoline (E150-E450) - 2008-09” article via Mitchell 1 data.
WARNING: The TPMS sensor battery may release hazardous chemicals if exposed to extreme mechanical damage. If these chemicals contact the skin or eyes, flush immediately with water for a minimum of 15 minutes and get prompt medical attention. If any part of the battery is swallowed, contact a physician immediately.
When disposing of TPMS sensors, follow the correct procedures for hazardous material disposal. Failure to follow these instructions may result in serious personal injury.
NOTE: The TPMS sensor cannot be removed without disassembly of the wheel and tire.
NOTE: Failure to follow the instructions below may result in damage to the TPMS sensor.
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).
1) Using a T10 Torx, remove the valve stem-to-TPMS sensor screw.
2) 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.
NOTE: When installing a new wheel, always install a new valve stem and reuse the TPMS sensor from the previous wheel if possible. The TPMS will not have to be trained if the sensor is reused.
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.
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 to13 in.-lbs. (1.5 Nm).
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.
NOTE: Use only a soap and water solution to lubricate the tire. Use of anything other than soap and water may result in damage to the TPMS sensor.
2) Lubricate the valve stem with soapy water and install the valve stem and TPMS sensor assembly into the wheel using a block of wood and a suitable valve stem installer.
NOTE: Do not mount the tire at this time.
3) Make sure the valve stem rubber is fully seated against the wheel.
4) Position the wheel on the turntable of the tire machine, then lubricate and position the bottom bead of the tire on the wheel.
6) Inflate the tire to the pressure specified on the Vehicle Certification (VC) label located on the driver door or door pillar.
7) Install the wheel and tire.
8) If a new sensor has been installed it must be activated (see “Tire pressure sensor activation” and trained (see “Tire pressure sensor training”). ■
