All About Your Toyota’s Tire Pressure Monitor

When you buy a Toyota, you know you’re getting the best of the best. You’re going to experience the best of performance, the highest efficiency, the best technologies, and the most advanced safety features. Just because you have the best of everything doesn’t mean you know how it all works, though. Such is the case for most people when it comes to their tire pressure monitor.

It’s one of those safety systems that has been around for a while but only recently became commonplace. Politicians spitballed about tire pressure monitor systems, or TPM systems, after the Firestone recall in an effort to reduce accidents because of tire problems. The solution manufacturers came up with is a system that monitors tire pressures and warns you when your tire pressure is low.

Here’s how they work:

Indirect TPM systems are the minimum standard for tire pressure monitor systems. These systems work on radio frequency identification tags (RFID), sending a signal to a module in the car that compares the tire pressure to an allowable threshold. It’s all very technical, but the result is this: if your tire pressure is higher or lower than it should be, your TPM light comes on to warn you.

Indirect TPM systems give you a general system warning, not the specific tire that is causing the condition, so you’ll have to check your tire pressures sooner rather than later to find out.

Direct TPM systems operate in much the same way. Sensors in each wheel report back to the vehicle’s module, communicating the tire’s internal pressure. If the tire pressure is too high or too low, it illuminates your TPM light and gives you a warning.

The difference from the indirect system is that you’ll know exactly which tire. The warning will inform you of the tire’s position, and will tell you if it’s more than one as well.

How do you use the Tire Pressure Monitor system?

Drive your Toyota like normal. You don’t need to activate or reset the tire pressure monitoring system. It functions in the background without you ever knowing, unless there’s a problem with your tire pressure. If you happen to get a TPM warning on your dash, don’t wait to get it checked out. If you actually do have a leaking or flat tire, the TPM system can save you money on tire replacement and prevent you from driving an unsafe car. If your Toyota’s tire pressure monitoring system warning comes on, check your tire pressure. Then, bring your car to Jay Wolfe Toyota of West County, where we’ll get it fixed up and get you back on the road in no time.
