TPMS Service in New Castle, DE

The little horseshoe-shaped light with an exclamation point in the middle is the notorious TPMS light. At Zee's Alignment & Autocare, we see that light on New Castle dashboards every single day. Sometimes the fix is a few seconds of air. Sometimes a sensor has quietly died after years of service. Either way, we'll figure out what's actually going on and fix it without guessing.

What TPMS Does

Every vehicle sold in the U.S. since 2008 has TPMS. Small battery-powered sensors inside each wheel measure tire pressure and radio the reading to your car's computer. When any tire drops roughly 25% below the recommended pressure, the light comes on. It's a safety system. Underinflated tires wear faster, hurt fuel economy, and are a leading cause of blowouts on highways like I-95.

Why Your TPMS Light Is On in New Castle

This is the case in most vehicles (not all):

Solid light: low pressure.

Flashing light, then solid: system fault.

If the light blinks for 60 to 90 seconds when you start the car and then stays on, your TPMS itself has a problem. Usually that means a dead sensor battery, a damaged sensor, or a sensor that lost communication with the vehicle.

Even if the TPMS light stays on after you’ve installed new or used tires, the light won't go away on its own. The tire sensors may not have been relearned by the vehicle, or one may be damaged. We can also handle issues like this at our New Castle shop.

Common TPMS Fixes

Most TPMS visits fall into one of these categories:

Pressure check and top-off – Fast and often all you need.
Leak repair – If a tire keeps losing air, we find and fix the source, then reset the system. In severe cases, you may need replacement tires.
Sensor replacement – TPMS sensor batteries are sealed and last 5 to 10 years. When one dies, we replace the sensor. We handle this on most makes and models.

We get how annoying the TPMS light can be, and it's tempting to slap a piece of tape over it. But TPMS is the only warning you'll get before a slow leak becomes a flat. A quick diagnosis at our New Castle shop costs far less than a tow.

Most TPMS work takes under an hour. During that time, enjoy our waiting area with free Wi-Fi, beverages, and snacks.
