What Does the Tire Pressure Sensor Fault Tell You?

Back in early 2007, a legislation requiring automakers to install a tire pressure monitoring system (TPMS) on every light vehicle they make was approved. This legislation was a safety measure for cars and encourages efficiency for the vehicle’s operation. As a result of this act, the tire pressure sensor fault was introduced.

Have you ever experienced having one of your tires running relatively deflated (with less than the allowable tire pressure) for a long time? Maybe it’s time that you be more vigilant in conducting a thorough maintenance and include your tires and see to it if they are in good condition. This article will shed the light on what does the tire pressure sensor fault tell you about the condition of your tires. Read, on!

What is the Tire Pressure Monitoring System (TPMS) all about?

To be able to know if your tires are in good working condition, car manufacturers installed the TPMS device where it has sensors that check the pressure of your tires and compare them to the normal operating pressure.The TPMS enables the driver of a vehicle to monitor if one or more of its tires is operating below the minimum allowable pressure.

Sensors are usually installed in each tire’s air chamber. If a sensor reads a pressure below the allowable limit, the system triggers the illumination of the TPMS light. If the TPMS signal light gleams, you must check your tires manually for any damage or leak.

However, if you do not find any damage or leak to your tires and they are still out of pressure, better to inflate your tires to their allowable operating pressure. You can check out your tire manufacturer’s recommended tire pressure written on the tire’s sidewall. If the tire has leaked or is damaged, you must replace it immediately with your spare.

Additionally, the usual standard tire pressure recommended by tire manufacturers is between 30 and 32 psi (pound per square inch). For optimum performance, some car enthusiasts used a tire pressure of up to 35 psi, especially when they are traveling with a heavier load (such as increased in passengers).

For a quick tire inflation, be sure you have the “TIREWELL 12V Tire Inflator-Heavy Duty Double Cylinders Direct Drive Metal Pump 150PSI, Compressor with Battery Clamp and 5M Extension Air Hose, SUVs/Trucks/Vans/RVs" on your trunk. This handy and portable inflator has a 300 cm (9.8 feet) charging cable and could be charged into your car’s cigarette lighter port.

What does the TPMS light indicate?

The sensors of the TPMS are also subjected to tear and wear, they have to be maintained periodically to have an accurate reading. Furthermore, the TPMS light could come in either solid or flashing light when the sensors are in operation. A TPMS in solid light may tell you a sensor reading of under-inflated tires which will stay lighted until the issue is corrected.

On the other hand, a flashing TPMS light is a usual indication that there is something wrong or a failure in the system. In this case, it is either the receiver is not identifying the signal of the tire sensor or one of the sensors is malfunctioning. At this instance, it is better to have your TPMS be checked promptly by a qualified car technician.

If you have a Cadillac or a Chevrolet, an excellent replacement for your TPMS sensors, if replacing them is inevitable, try the “Dorman 974-012 Tire Pressure Monitor System Sensor”. This is a valve stem sensor and has complete tire monitor sensor and transmitter. This is available readily from Amazon.

What may happen if you have under-inflated tires?

When you are running with under-inflated tires, there are many possible scenarios that could happen. First, low-pressure tires will not handle properly that may cause an accident that can endanger lives and properties. Secondly, under-inflated tires could lead to overheating and may result in the disintegration of the tire, which could also be the cause of an accident.

Additionally, when you run with under pressure tires, you risk the possibility of wasting fuel, rated at 1% per 3 psi of pressure under the standard. So, you are bound to lose a great amount of money (for fuel) when you run your car under pressure.

Consequently, your tires would not last longer as expected when you always run them under pressure, you are also bound to replace them as often compared to running with the right tire pressure. Another waste of time and money.


There are surely more to know on what does the tire pressure sensor fault tell you whenever your car’s TPMS light is illuminated. You will certainly have to act immediately when your car’s safety devices have something to tell you. Also, pick the right accessories (an excellent quality sensor, perhaps) so your safety system may run smoothly as possible without much maintenance.

Also, you should have a good tool (like a handy and portable tire inflator) to keep your tires on the right pressure anytime and anywhere.
