What does TPMS mean on a Honda CRV – The TPMS System ( Tire Pressure Monitor System ), better known as TPMS Sensor or Tire Sensor, is a system that allows the electronic control of the vehicle to constantly monitor the pressure conditions in each of the wheels of the vehicle, emitting a signal warning light to the driver that lights up in the cluster or dashboard once it is detected that one of the tires is deflated and with a pressure below the established percentage that is generally 25% lower than the required operating pressure.

The TPMS or Tire Pressure Monitoring Systems are composed of a valve and a sensor coupled in a single mechanism, and although all are similar, they are mainly designed in two types of technology: TPMS direct sensor systems and indirect TPMS systems. The difference between both systems lies in the way the machine measures the pressure, since indirect systems the sensor is installed inside each tire allowing a much more effective measurement in comparison with the indirect system, which calculates the pressure of the pneumatic by means of an indirectly made approximation using the different data of the sensors of the ABS system.

To transmit the information, the direct TPMS uses a radio frequency RF through which the ECU (Computer Engine) receives the data of pressure and other variables, each sensor is installed independently on the wheels and requires programming on the computer so that the sensor is identified and received its reading. When the TPMS witness it lights up on the dashboard, indicates that there is a tire below the required pressure, in this case, if the warning light stays on, the recommendation is that the driver take precaution and perform an immediate review of the tire’s condition to restore the pressure up to its normal stop. On the other hand, if the TPMS warning light comes on and flashes, a diagnosis with an automotive scanner and a revision is required due to a fault in the system related to its operation.

In the United States as of September 1, 2007, the implementation of the TPMS is mandatory ( TREAD Act ) for passenger vehicles and will cost up to 10,000 pounds, at the Latin American level it can also be found in mid-range vehicles and high from the years 2008 onwards.

 

How do TPMSs relate to safety and fuel economy?

Safety: Study results * show that a tire can reduce its pressure by almost half without being visible to the naked eye. The pressure of the wheel is of vital importance for driving safety. Normally a puncture on roads is preceded by a low pressure on the tire. Aspects such as steering, even braking, vehicle stability are directly related to the pressure on the wheels.

Fuel Economy and Emission Reduction: Correct tire pressure drastically influences fuel economy, tire pressure drop affects Kilometers / Gallon mileage. This, in turn, is reflected in the environmental impact and more and more authorities are more demanding with this type of controls, the technical committee must be consistent with these same needs.

The truth is that today there is much ignorance of what this simple light TPMS means or the importance that entails. It is common to find that many of the faults related to the operation of the system are due to the fact that tire replacements usually damage the sensors due to poor handling or installation. It is important to be aware of this issue and as technicians, we have the responsibility to know and understand the operation of these mechanisms to give adequate support to customers in the workshop.
