FAQ

What is TPMS

Tire Pressure Monitoring System – monitor the air pressure of a vehicle’s tires and report this information in real time to the driver. It is designed to alert driver to check tire pressure by signaling a low pressure light, some advanced system can even display tire pressure in PSI on the dashboard. TPMS is definitely the one of most critical parts of a vehicle’s safety system.

What is a TPMS Relearn?

It is a pairing process to let car’s ECU (electronic control unit) register new sensor’s ID and location, so the electronic system can verify to accept data transmitted from paired sensors only.

All replacement sensors are required to be paired to vehicle by following standard relearn procedure specified by vehicle manufacturers. There are 3 types of relearn method are commonly used, please click on following links for more information.

What is the difference between Pre-programmed and Blank sensors?

Pre-programmed sensor is ready to pair with vehicle as the communication protocol has been programmed into sensor’s flash drive. All that’s left to do is to pair the sensor to car’s ECU by performing standard relearn procedure.

Blank Sensor requires a TPMS programmer or programming-able servicing tool to write the vehicle specific protocol/software into sensor’s flash drive. Car’s ECU will not detect or recognize the sensor that has not been programmed.

Why my TPMS tool is not able to detect or read new sensors?

Reasons may vary, we summed up the most common scenarios as follows.

  1. The tool used has not been updated for more than a month. Keep in mind that all tool manufacturers are constantly updating vehicle data and relearn software on a monthly basis, an outdated software/firmware can lead to all kinds of programming error and relearn failure.
  2. Incorrect vehicle model, make and year was selected when trying to trigger or read TPMS sensor(s). It’s very common for car owners to misidentify their vehicle model or production year, the best way to verify such information is through performing a VIN (vehicle identification number) lookup.
  3. Incompatible radio frequency. There are 2 major radio frequencies used for tire sensor to communicate with ECU (electronic control unit), 315 MHz and 433 MHz. Some car makers switch the frequency from one to another after redesigning an active model during same production year. Please simply scan the factory sensor to verify frequency if you have a TPMS servicing tool or scanner. Or you can contact car dealer or local professional to verify the information for you.

Is TPMS reset or sensor replacement DIY friendly?

Generally speaking, TPMS maintenance and repair require decent level of knowledge, experience, skills and special tool/device to perform the task. Most of the mechanics and technicians from tire shops aren’t trained properly or lacking ability to troubleshoot TPMS. We recommend getting your sensors replaced and paired by certified service that specializes in tire sensor replacement and TPMS reset.

How to program / reprogram MOREsensor

Reminder – 
Always update your tool before programming or at least once every month as tool manufacturer normally update software/firmware and vehicle data quite frequently.

All the tools listed above support wireless programming, please select “Combi Sensor” under brand “Mobiletron” for sensor type option.

Difference between sensor Serial Number and Sensor ID? Where to find it?

Sensor Serial number is referring the sensor’s hardware number, and it is usually used to identify the sensor by programming tools. You can find Serial number printed on the sensor

Sensor ID is created by programming tools and its the sensor identity to car’s ECU (use during relearn/pairing process).
You can retrieve sensor ID by triggering the sensor with relearn or programming tool

Does MOREsensor come with Warranty?

Yes, all of our TPMS sensors for sale online come with 8 years limited warranty on parts, and 3 years warranty on battery.

Why my car still indicates low tire pressure after sensor is replaced?

If you’re seeing low pressure light on after sensor replacement, your TPMS is most likely failed to communicate with the new sensor(s). It is possible that the sensor(s) wasn’t installed or paired properly. See following common scenarios and consult us for further assistance.

  • Bought sensor(s) in wrong frequency
  • Mistaken about vehicle model year
  • Your vehicle trim level is not compatible
  • An outdated scan tool or OBD diagnostic tool was used
  • Incorrect relearn procedure was taken

(see self-troubleshoot guide)

Lo-line TPMS vs. Hi-line TPMS

Low Line TPMS uses a symbolic light to alert driver when system detects low pressure

High Line TPMS displays real-time tire pressure from each tire location to notify driver the status

How to verify a sensor's compatibility before installation?
  1. First thing first, you have know the correct vehicle information (make, model and year) and what radio frequency the vehicle utilizes.
  2. A TPMS servicing tool or scanner is required to perform compatibility check
  3. Pre-scan the new sensor
    if your tool/scanner is able to read the sensor, that means it’s programmed with correct protocol. The other way around, do not even attempt to install the sensor because it’s most likely going to fail.
Can I reprogram or modify a pre-programmed sensor?

Yes you can!

With our universal programmable tire sensor, you will be able to reprogram it as long as you have one of the following compatible tools.

How long does a tire sensor last?

The average lifespan of MOREsensor TPMS sensor is roughly around 8-10 years according to 12000-15000 miles of driving per year.
