Product overview This four piece tire pressure monitoring sensor set replaces factory sensors and provides direct TPMS function for compatible vehicle models. The sensors operate at 433MHz, come as a normal packet, and are supplied preprogrammed for specific vehicle makes and years. Activation with a scan tool is required to complete sensor registration. Key benefits Reliable tire pressure monitoring: Provides accurate, wheelspecific tire pressure data to the vehicle TPMS after activation. Preprogrammed for fit: Sensors arrive preprogrammed to match listed part numbers and vehicle applications, reducing programming time at installation. Durable battery performance: Battery life information included as provided 1) battery life listed as about 3 year, and 2) manufacturer note that battery is made to last up to 10 years of normal use and can withstand 125 degrees . Both statements are provided as given for customer reference. Leak fit: Sensors are designed to fit rims securely to help prevent air leaks when installed correctly. Fast installation: Simple installation procedure that typically takes about 5 minutes per sensor once mounted and synchronized with the vehicle. Specifications Quantity: 4 pieces Frequency: 433MHz Packet type: Normal packet Interchange part numbers: 2197279, 2401839, JX7J1565DA9, JX7T1A180CA, JX7T1A180DA, JX7Z1A189A Model numbers referenced: 2197279, 2401839, JX7J1565DA9 Compatibility note: Fit for 2020, 2021, 2022, 2023 models including Focus, Kuga, Puma, SMax, Transit Activation: Requires a scan tool to activate and register sensors with vehicle TPMS Performance and use Function: Electronic TPMS sensors monitor internal tire air pressure and transmit data at 433MHz to the vehicle receiver. Installation: Mount sensor to wheel valve, torque to vehicle specifications, then use a compatible scan tool to activate and sync. After synchronization, the vehicle will display the proper tire pressure readings for each wheel. Reliability: Sensors have been tested for installation performance. Proper installation and activation are to ensure correct operation. Practical applications Replacement of failed or low battery TPMS sensors on compatible 2020 to 2023 vehicles listed above. Fitting TPMS sensors to aftermarket wheels or spare rims when changing wheel sets for seasonal tires. Fleet maintenance where multiple sensors are replaced or serviced to restore accurate tire pressure monitoring across a vehicle group. What is included Four TPMS sensor units supplied as one normal packet, preprogrammed to the listed interchange and model numbers. Important reminders These sensors require activation and registration with a scan tool after installation. Confirm vehicle compatibility with the listed model years and vehicle names before . Follow vehicle manufacturer torque and safety procedures when installing wheelmounted sensors.
