How To Fix Ford Bronco Tire Pressure Sensor Fault - Easy And DIY

By Nick Marchenko, PhD

Hey there, folks! If you own a Ford Bronco and are scratching your head over that pesky tire pressure sensor fault, I'm here to guide you through the fix. Let's break it down step-by-step:

What's the Deal with the Fault?

In simple terms, every tire has a little gadget, a pressure sensor, that's powered by a battery. Over time, this battery runs out of juice. Now, since this battery is sealed inside the sensor, you can't just replace the battery. Instead, you might need to get a new Tire Pressure Monitoring System (or TPMS for short).

Quick Fix: The Manual Reset

Before diving into the techy stuff, there's a basic trick you can try:

Spot your hazard light button? Give it a quick press three times. You should hear the truck honk, signaling it's ready for the next step.
Your dashboard will guide you from here. It'll tell you which tire to check first.
Either let out a bit of air from the tire it points to or use a good ol' magnet. The system should then move you to the next tire.

The Deeper Dive: Tools You'll Need

If the quick fix doesn't do the trick, here's the gear you'll need:

• A wired ELM 327 OBD2 tool (Skip the Bluetooth ones - they can be a bit finicky for this job).
• A laptop with this software called FORScan. Make sure you register once you download it. Sometimes, getting the activation code can take a bit.

Connect the Dots

• Hook up the ELM tool to your Bronco and then to your computer.
• Fire up FORScan and hit the 'connect to vehicle' button.
• The software will guide you. Sometimes, it'll ask you to switch between HS-CAN and MS-CAN settings.

Shutting Off That Annoying Sensor Light

• In FORScan, look for an icon that resembles a computer chip.
• Choose the right module (it's often labeled "DOM").
• Find the "Tire Pressure Monitor" option and switch it from "enabled" to "disabled".
• Save this new info to your vehicle's system.
• Turn your vehicle's ignition off and then back on to finalize the changes.

Final Check

After these steps, your Bronco should be free from that nagging tire pressure alert. But remember, after this, you won't get automatic alerts for tire pressure, so keep an eye on it from time to time.

If any of this sounds like mumbo jumbo or you need more help, drop a comment or swing by the shop, and I'll be glad to help! Safe driving!
