Are all GM TPMS sensors the same?
No, not all General Motors (GM) Tire Pressure Monitoring System (TPMS) sensors are the same. GM uses different TPMS sensor types and technologies across its vehicle models and model years. The specific TPMS sensor required depends on the particular GM vehicle.
Understanding GM TPMS Sensors
GM has utilized several TPMS sensor designs and technologies over the years. The main TPMS sensor types used in GM vehicles include:
- Direct TPMS sensors: These sensors are mounted inside each wheel and directly measure the tire pressure.
- Indirect TPMS sensors: These sensors use the vehicle's anti-lock braking system (ABS) to indirectly monitor tire pressure by detecting differences in wheel rotation speeds.
- Hybrid TPMS sensors: These sensors combine direct and indirect TPMS technologies.
The specific TPMS sensor type required depends on the GM vehicle model and model year. For example, many newer GM vehicles use direct TPMS sensors, while older models may have indirect or hybrid systems.
Factors Affecting TPMS Sensor Compatibility
In addition to the sensor type, other factors that can affect TPMS sensor compatibility in GM vehicles include:
- Sensor frequency: GM TPMS sensors operate at different radio frequencies, such as 315 MHz or 433 MHz.
- Sensor shape and size: TPMS sensors come in various physical sizes and shapes to fit different wheel and tire configurations.
- Sensor programming: TPMS sensors must be properly programmed or "learned" to the vehicle's computer system.
It's important to consult the vehicle's owner's manual or a qualified technician to determine the correct TPMS sensor required for a specific GM model and year.
Do GM TPMS sensors need to be programmed?
If a new sensor is fitted, the BCM must be reprogrammed with its unique ID and its position on the vehicle.
What brand TPMS sensor does GM use?
The manufacturers of the GM TPMS are Schrader Electronics, VDO and TRW. The GM Model range utilising TPMS Technology includes the following brands: Chevrolet Aveo, Cobalt, Corvette, HHR, Impala, Malibu, Avalanche - TPMS Sensors. Colorado, Silverado, Equinox, Suburban, Tahoe, Trailblazer, Express, Uplander - TPMS ...
What year did GM change TPMS sensors?
The GMC Sierra was manufactured with 315 MHz TPMS sensors from 2004 through 2018. 2020 models are manufactured with 433 MHz TPMS sensors. However, 2019 models are manufactured with BOTH 315 and 433 MHz TPMS sensors.
Are TPMS sensors all the same?
In cars with factory-installed TPMS sensors, the sensors are always vehicle-specific. Automakers get these systems from specific suppliers, and the supplier can vary from model to model. If you use an incompatible TPMS sensor, it likely won't work with your car's system.
