How Toyota TPMS Sensors Work
Toyota TPMS (Tire Pressure Monitoring System) sensors work by constantly monitoring the air pressure in the tires and alerting the driver if the pressure in any tire becomes significantly low. Here’s how they function:
1. Description and Operation: The TPMS sensors in Toyota vehicles are designed to monitor tire pressure and transmit this information to the vehicle’s onboard computer system.
2. Warning Indicator Reset Procedure: In the event of low tire pressure, the TPMS system triggers a warning indicator on the vehicle’s dashboard to alert the driver.
3. System Retrain/Relearn Procedure: The TPMS system may require retraining or relearning after tire rotation or replacement to ensure accurate monitoring of tire pressure.
4. TPMS Replacement: TPMS replacement is necessary when the sensors fail due to mechanical or electrical issues, such as a broken accelerometer or low battery.
5. Direct and Indirect TPMS: Toyota vehicles use both direct and indirect TPMS systems. Direct TPMS uses sensors inside the tires to directly measure tire pressure, while indirect TPMS uses the vehicle’s anti-lock braking system (ABS) to monitor tire pressure based on wheel speed and other vehicle data.
6. TPMS Tool Training: Bartec, a leading company in TPMS systems, provides TPMS tool training and is involved in the implementation of TPMS systems for wheel and tire assembly plants and car plants worldwide.
7. Aftermarket Options: Aftermarket programming/coding options are available for drivers who choose not to install TPMS sensors on a dedicated set of track/race wheels and tires. However, this may come with limitations and risks.
In summary, Toyota TPMS sensors play a crucial role in ensuring that the vehicle’s tires are properly inflated, contributing to overall safety and performance.

What is the life expectancy of a Toyota TPMS sensor?
Most TPMS sensors run on batteries that are built into the sensor and these batteries are not replaceable. The life expectancy of the lithium ion batteries in a TPMS sensor is anywhere from 5-10 years.
How do TPMS sensors communicate?
These sensors constantly monitor tire pressure and relay this information to the vehicle’s onboard computer. So, how do TPMS sensors communicate with the rest of the system? They typically use wireless technology, such as RF signals, to transmit the collected data.
How do Toyota tire pressure sensors work?
It monitors all four of the tires on your Toyota and checks to see how much air is in each of them. The system has a series of sensors that keeps tabs on things such as the temperature of the air in your tires to determine whether or not they need to be filled with more air.
Do Toyota OEM TPMS sensors need to be programmed?
Every replacement TPMS sensor must be “relearned” to the vehicle following the prescribed OE relearn procedure, regardless of whether it is an OE or aftermarket sensor.
How do tire pressure sensors work when you rotate tires?
It’s not electronically processing the same kind of measurement you might see with a tire gauge. Instead, an indirect tire pressure monitor simply measures how fast your tires are rotating and sends signals to the computer that will actuate the indicator light when something in the rotation seems amiss.
How long do Toyota tire pressure sensors last?
5-10 years
TPMS sensors are designed to last for many years – 5-10 years is a likely lifespan. Given their cost, most drivers will be inclined to replace TPMS sensors on an “as needed” basis – in other words, only once their batteries have expired, or other TPMS components have failed.
What brand of TPMS does Toyota use?
The manufacturers of the Toyota TPMS are TRW Automotive and Pacific Industrial Corp. The Toyota Model range utilising TPMS Technology includes: 4 Runner – TPMS Sensors. Avalon – TPMS Sensors.
Why is my tire pressure light on when my tires are fine Toyota?
The causes can be a malfunction, or the weather changes. Other reasons why your TPMS light may still be blinking is because your tire may be damaged, or you might have gotten a recent tire replacement. Overall, the reasons can be vast, which is why it is best to take your car to a technician for professional diagnosis.
Do Toyota TPMS sensors have batteries?
Toyota (or Pacific) used a watch style battery for the sensor. There are no markings so I’m not sure it would be easy to find a place to buy one. If I were serious about, I’d do the research. The TPMS battery looks a bit like a CR2032, so I’ll use that battery.
How do TPMS sensors know which wheel?
Each tire pressure sensor sends out a radio frequency signal. In this signal is tire data and the sensor’s unique ID code. Each sensor position is matched or “trained” to the control module.
