TPMS Sensor

The replacement procedure for a Tire Pressure Indicator Sensor begins with a proper vehicle elevation on suitable support. Extract the tire/wheel assembly from the vehicle's framework. Before moving the tire from the wheel position its nickel-plated sensor valve and aluminum cap on a clean surface to avoid corrosion. The replacement materials should not be used for tirePressure Indicator Sensor or its components. The correct bead breaking method requires anglings the bead breaking fixture 90 degrees toward the valve stem while starting the tire iron or pry bar slightly clockwise of the sensor body while prying the tire bead loose. Use the tire machine to rotate the tire/wheel assembly clockwise until the tire bead reaches the wheel rim's outside edge before repeating this procedure for the bead on the inside. Eliminate all tire sealant evidence from the inside surface of removed tires as well as wheel surfaces after removal. To proceed with the installation you must first detach both the tire pressure sensor nut and sensor. Installation begins by cleaning the grommet sealing area before inserting the sensor into its wheel hole with the air passage directed toward the outside of the wheel. Assemble the sensor body parallel to the inner wheel surface before tightening it to 7 N.m torque (62 lb in). Starting with the mounting/dismounting head positioned at 180 degrees from the valve stem and the bead transition area located 45 degrees counterclockwise from the valve stem, charge the tire/wheel assembly through a clockwise rotation to embed the tire bead internally before repeating the process for the outside bead. The tire requires direct installation onto the wheel and users should know that replacement tire pressure sensors arrive in OFF mode so the sensor must reach 40 km/h (25 mph) for at least ten seconds of tire/wheel rotation to activate the roll switch. The process ends by putting the tire/wheel assembly onto the vehicle before lowering it down then teaching the tire pressure sensors.

The process for replacing the Tire Pressure Indicator Sensor starts with raising the vehicle on proper supports then removing the tire along with its wheel assembly. When preparing to remove the tire find a clean surface where you can set both the aluminum cap and nickel-plated valve of the sensor. Before you begin separating the tire bead from the wheel, point the bead breaking fixture directly toward the valve stem then slowly insert the tire iron just ahead of the sensor body and pry the tire bead over the mounting/dismounting head. The tire machine should operate clockwise on tire/wheel combinations to shift tire beads into wheel rim positions outside first followed by inside positions. The tire should be checked for residual tire sealant inside which must be cleaned off from both tire and wheel surfaces following removal. You should also remove the tire pressure sensor nut alongside the sensor itself. Start with cleaning the sensor's grommet sealing point then put the sensor into the wheel opening facing away from the air passage and use a 7 N.m torque setting to install the sensor nut at a 90-degree angle to the wheel surface while tightening it to 62 lb in. Use the mounting/dismounting head at a 180-degree angle to the valve stem to reinstall the tire by rotating the tire/wheel assembly clockwise during bead placing inside the wheel rim. Follow this by repeating the operation for the outer bead. When installing the tire on the wheel keep in mind that service replacement tire pressure sensors come in OFF mode so you need to spin them above 32 km/h (20 mph) for at least 10 seconds to activate the internal roll switch. The final task involves mounting the tire/wheel assembly to the vehicle followed by a vehicle lower method and sensor learning for the tire pressure systems.

Start the tire pressure indicator sensor replacement by mounting the vehicle on a proper support. Remove the tire/wheel assembly that sits on the vehicle. Set the sensor's cap and valve on a dry clean surface before tire removal because aluminum forms the cap while nickel plating protects the valve from corrosion. The sensor replacement requires using only original components because material substitutions are prohibited. To successfully separate the tire bead from the wheel point the bead breaking fixture at 90 degrees toward the valve stem then gently drive the tire iron or pry bar counterclockwise of the sensor body as you pry the tire bead over the mounting/dismounting head. Rotate the tire/wheel assembly through complete turns using the tire machine until the tire bead moves to the wheel rim's external portion followed by moving the second bead to the rim's inside edge. Before reinstalling the tire you should eliminate tire sealant from inside wheel surfaces. Following removal of the tire pressure sensor nut comes sensor removal. Clean the grommet sealing area from dirt then insert the sensor through the wheel hole with air passage pointed away from the wheel. Torque the sensor nut to 7 Nm (62 lb in) while maintaining the sensor body parallel to the inside wheel surface. To replace the tire begin by orienting the mounting/dismounting tool 180 degrees from the valve stem and positioning the bead transition area 45 degrees offset to the left of the valve stem. Continue rotating the tire/wheel setup clockwise during the tire bead transition into the wheel rim then perform the same process for the external bead. The service replacement tire pressure sensor comes in OFF mode so you must spin the wheel above 32 km/h (20 mph) for at least 10 seconds to trigger the internal roll switch. Place the tire/wheel assembly onto the vehicle followed by vehicle lowering and sensor learning of tire pressure sensors.

During sensor replacement start by elevating the vehicle on appropriate supports. Separate the tire/wheel assembly from the vehicle's chassis. Before taking off the tire you should set the sensor's cap and nickel-plated valve on a clean platform because aluminum caps and nickel-plated valves guard against corrosion. The sensor installation requires only authentic materials that must never be replaced by alternatives. During tire bead separation from the wheel use the bead breaking fixture at a 90-degree angle from the valve stem and carefully insert a tire iron or pry bar slightly clockwise beside the sensor body before lifting the tire bead over the mounting or dismounting head. Apply the tire machine to rotate the tire/wheel assembly by the clockwise method during the bead transfer process to the wheel rim edge both for inside and outside beads. Remove the tire from the wheel then work to remove all tire sealant residue from its interior surfaces. The independent procedure starts with sensor nut removal followed by sensor removal. Installation requires cleaning the grommet sealing surface before placing the sensor rod inside the wheel hole with air flow directed away from the wheel butted next to the wheel's interior surface before torquing the sensor nut to 7 Nm (62 lb in). To install the tire properly place the mounting/dismounting head at 180° distance from the valve stem while setting the bead transition area 45° counterclockwise from the valve stem before you rotate the tire/wheel assembly clockwise to move the tire beads into the wheel rim cavity. Repeat this process for the outer bead. The service replacement tire pressure sensor requires spinning above 32 km/h (20 mph) for at least 10 seconds to operate correctly because it ships in an OFF mode. Once the internal roll switch is activated the wheel installation can proceed. Following sensor initialization, install the tire/wheel assembly and let the vehicle lower itself before sensor learning proceeds.

Set the sensor's cap and valve on a clean area while verifying the aluminum cap with nickel-plated valve to stop corrosion. When replacing parts always use the correct part number with the specified torque value to prevent damage. Put the bead breaking fixture at a right angle to the valve stem before inserting the tire iron or pry bar slightly ahead of the sensor body while lifting the tire bead over the mounting/dismounting head. The tire machine should rotate tire/wheel assemblies clockwise to position the tire bead correctly on the outer wheel rim before removing the tire from the wheel. Tires containing sealant will require a complete removal of all remaining liquid residues from wheel and tire surfaces. The sensor nut and the sensor must be detached from the installation. Insert the sensor into the wheel hole with the air passage aimed toward the outside of the wheel while clearing any debris from the grommet sealing zone. Service replacement tire pressure sensors come off before installation in OFF mode requiring that the tire/wheel assembly reaches speeds above 32 km/h (20 mph) continuously for 10 seconds to activate the switch inside the sensor. Torque the sensor nut to 7 N.m (62 lb in) with the sensor body facing parallel to the inside wheel surface. Place the mounting tool at a 180-degree angle to the valve stem when installing the tire and orient the tire beads 45-degrees counterclockwise from the valve stem direction. Use a clockwise rotation of the tire/wheel assembly to push the tire bead inside the wheel rim then repeat this procedure for the outer bead before tire installation. The service replacement tire pressure sensor arrives in OFF mode requiring at least 10 seconds of tire/wheel assembly rotation above 32 km/h (20 mph) to activate the sensor's internal roll switch for closure. After installing the tire/wheel assembly onto the vehicle and letting it lower down learn the pressure sensors.
