Cars have become so reliable nowadays that we are indifferent to their complexity. We think that any issue is easily corrected and that every system inside of them will always work just fine.
But the vehicle you drive is anything but simple. In fact, road-going cars are some of the most complex machines, with numerous mechanical and electrical systems that ensure high-speed transportation that is comfortable, fun, safe, and reliable.
Our cars even communicate everything with us. For instance, the Tire Pressure Monitoring System (TPMS) can tell you when one of the tires is underinflated so you can take measures. No more gauges and dirty hands, right?
Well, just like any complex structure, the TPMS system isn’t perfect. First of all, it doesn’t replace a proper gauge, as it doesn’t show the exact pressure reading (except in some expensive premium vehicles). Moreover, it can show false readings from time to time due to various issues.
As a result, one of the most frequent questions I got in my shop was: why is the low tire pressure light illuminated, yet the tires are fine? Let’s investigate that false alarm and make sure it never happens again!
