The Launch LTR-05 is a programmable TPMS sensor for direct tire pressure monitoring systems. This universal sensor continuously measures the current tire pressure and the internal temperature of the tire during driving. The device is designed with a dual-frequency architecture, meaning it operates on both the 315 MHz and 433 MHz frequency. This allows the sensor to offer broad application coverage and be used as a replacement part for defective original (OEM) sensors in a wide range of passenger cars and light commercial vehicles.
The measured data is periodically transmitted wirelessly via an RF signal to the control unit (ECU) of the vehicle system. Before the unit can communicate with the vehicle, it must be paired with a unique sensor ID. This ID can be digitally cloned from the old sensor or newly generated. This programming process only takes place via specific hardware from the same manufacturer. After physically mounting the aluminum valve in the rim and completing the learning process (OBD, automatic or static), the internal processor monitors pressure fluctuations to timely alert the dashboard in case of deviations.
ADVANTAGES
KEY POINTS
Applications and functionalities
This direct-fit tire pressure sensor collects current rim data and provides essential measurements to the onboard computer to support safety systems.
- Tire pressure measurement: Records the internal air pressure of the tire within a range of 0 to 800 kPa and transmits it wirelessly to the receiver to activate a warning light in case of pressure loss.
- Temperature recording: Measures the internal air temperature inside the tire with an accuracy of ±5 °C to signal thermal overload before it results in road damage or a blowout.
- Vehicle communication: Generates a continuous RF signal at 315 MHz or 433 MHz that corresponds with the data protocol implemented by the vehicle manufacturer for interference-free diagnostics.
Special features and capabilities
The sensor is built around a flexible memory architecture, enabling specific technical procedures in the workshop.
- ID cloning: Enables the technician to digitally copy the hexadecimal serial number of the defective original sensor to the LTR-05. This avoids the need to put the vehicle back into OBD learning mode and allows the new sensor to be recognized immediately.
- Over the air programming: Allows wireless flashing of the protocol software to the sensor via a Launch TPMS tool. This can be done without physically connecting the sensor and even works through the tire rubber once mounted.

Technical specifications
General
- The manufacturer of the sensor. Useful if you already own a programming device from the same brand.Brand
- Launch
- The type of valve used to fit the sensor into the rim. This must match the rim and the car's original valve.Valve type
- Aluminium screw-in valve
- A sensor that can transmit on both frequencies fits more cars. You then need fewer different sensors in stock.Works on 315 and 433 MHz
- Yes
Measurements
- The pressure range within which the sensor can measure tyre pressure. A wider range also suits heavier vehicles.Tyre pressure measuring range
- 0 to 800 kPa
- The maximum deviation of the measured tyre pressure. The smaller the figure, the more precise the warning.Pressure accuracy (±)
- 10 kPa
- The temperatures at which the sensor operates and measures. This matters because tyres heat up during hard driving and braking.Temperature range
- -40 to 125 °C
- The maximum deviation of the measured tyre temperature.Temperature accuracy (±)
- 5 °C
Programming
- The sensor can take over the code of the old sensor. This means the new sensor does not need to be relearned by the car.ID cloning
- Yes
- The sensor is set without a cable using a programming device. This works faster, even when the sensor is already fitted in the tyre.Wireless programming
- Yes
Battery and transmitter
- The voltage of the built-in battery that powers the sensor.Battery voltage
- 3.0 V
- The strength of the signal the sensor sends to the car. A stronger signal is received more reliably.Transmission power
- 5 to 8 dBm
Dimensions and weight
- The dimensions of the sensor. This matters because the sensor must fit in the rim without touching the tyre.Dimensions
- 27.2 x 20 x 76.4 mm
- How heavy the sensor is without the valve. A lighter sensor disturbs the wheel balance less.Weight without valve
- 24 g
Other specifications
- Product model
- LTR-05 (TSENSOR-05)
- Operating frequency
- 315 MHz / 433 MHz (Dual-Frequency)
- Storage temperature
- -40 °C to 125 °C
- Valve nut tightening torque
- 4 Nm
