How does Chevy TPMS work?

How Chevy TPMS Works
The Tire Pressure Monitoring System (TPMS) in Chevrolet vehicles, including the Silverado, uses radio and sensor technology to check tire pressure levels. The system monitors the air pressure in the tires and provides alerts if it senses that one or more tires isn’t at the recommended pressure. Here’s how it works:
Direct TPMS System:
– The Chevrolet Silverado is manufactured with a direct TPMS system, which means it uses sensors inside each tire to directly measure the tire pressure and transmit this information to the vehicle’s ECU.
Tire Rotation and TPMS Reset:
– Chevy recommends rotating tires every 7,500 miles and resetting the TPMS system by performing a TPMS relearn after tire rotation. This relearn process transfers the new location of the TPMS sensors to the vehicle’s ECU.
Placard Pressure Adjustment:
– When upsizing tires/wheels or replacing them with off-road or low-profile tires, Chevy recommends using specific branded tools to change the placard pressure for the Chevrolet Silverado.
Sensor Replacement:
– After a wheel or sensor replacement, it is also recommended to perform a TPMS reset to ensure the system recognizes the new sensors.
In summary, the Chevy TPMS uses sensors to monitor tire pressure and provides alerts to ensure that the tires are at the recommended pressure levels for safe driving.

Does TPMS tell you which tire?

Tire pressure monitoring systems (TPMS) may warn you if your tires are under- or over-inflated, helping increase your fuel economy and even potentially preventing a tire blowout. What It Does Not Do: May not specify which of the tires needs attention.

Why is my TPMS light on but tires are fine?

For instance, extreme cold or hot temperatures can also be the reason why your TPMS light turns on. This is due to the contraction that an extreme temperature causes when you are trying to drive in the cold or heat. Other times, the tire pressure light can turn on and off due to any the malfunctions in the sensors.

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.

Can I reset my TPMS myself?

Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait about 20 minutes for the sensor to refresh. You will find the tire pressure monitor reset button under the steering wheel. Refer to your vehicle’s owner’s manual if you can’t find it.

How do Chevy tire pressure sensors work?

Let me show you so here is your real speed sensor on top of the wheel hub. So if your tire pressure falls too low your tire is going to spin. At a different rate than all the other tires.

What controls the tire pressure sensor?

Direct TPMS. Direct TPMS (dTPMS) directly measures tire pressure using hardware sensors. In each wheel, most often on the inside of the valve, there is a battery-driven pressure sensor which transfers pressure information to a central control unit which reports it to the vehicle’s onboard computer.

How do TPMS sensors get power?

Once mounted inside the tire, the tire pressure sensor is a stand-alone device. It is powered by a battery that has a limited operating life. Due to it being mounted inside the tire, the driver does not frequently check tire pressure sensor battery.

How does TPMS sensor work without battery?

The sensor is interrogated by an radio-frequency signal—no battery is required—first exciting, then transmitting the three resonant SAW frequencies from which independent pressure and temperature are subsequently determined.

How do you reprogram a Chevy TPMS?

Once the TPMS light is on, hold the TPMS reset button until the icon flashes three times. Start your vehicle and wait about 20 minutes to allow the sensor to reset. To find your TPMS reset button, check out your vehicle owner’s manual! Usually the button is under the steering wheel.

Is there a battery in the TPMS sensor?

Use the end of the wrench push between the two black columns. And pop the old battery loose. Make sure you recycle that in appropriate facility. Take your new battery.
