The Ford Mustang has gotten itself a legendary status as one of the best muscle cars out there. This car’s performance is not something to be sneered at, and it is well-known for its excellent handling and quick acceleration.
One of its more sensitive systems is the tire pressure monitoring system (TPMS). This safety device can malfunction, especially when a TPMS sensor reset is not done after changing tires. In this case, the TPMS light comes on and stays on when the vehicle is started.
Why Do You Need to Do a TPMS Sensor Reset?
The TPMS of your Ford Mustang is what allows you to check the pressure of your tires. The system monitors the air pressure of all four tires and alerts the driver if one or more of them becomes underinflated. This is a potentially life-saving feature, as under-inflated tires can negatively affect performance and safety.
But how exactly does the TPMS know if your tire’s pressure level does not meet what’s recommended?
Every tire on your vehicle has a built-in sensor that measures the wheel’s circumference. These sensors or transponders communicate with your vehicle’s engine control unit (ECU), informing the system when a tire is underinflated.
If you’re changing a flat, have purchased new tires, or have just removed the wheels for other service, it’s important to reset this sensor. Otherwise, your factory-installed TPMS will not be able to communicate with your sensors, resulting in a false TPMS alert.
Many people find it inconvenient to deal with TPMS-related issues repeatedly. This is why some of them opt to disable their TPMS. You can consider this option if you no longer want to spend time and money on fixing your TPMS.
On the other hand, if you wish to keep using your TPMS, then it is essential that you know basic troubleshooting procedures.
How to Reset Your Ford Mustang’s TPMS Sensor
When you need to reset your Mustang’s TPMS sensor, these are the steps that you need to follow:
Turn the ignition key to the “ON” position, but do not start the vehicle.
The vehicle should be stationary, with the engine off and in a level position for at least 3 minutes before starting this procedure.
Press and hold the tire pressure monitoring reset switch until one or all of the following conditions has been met:
- The horn sounds three times.
- The TPMS telltale flashes three times.
- The instrument cluster displays TIRE LEARN ACTIVE message.
Press and hold the TPMS RESET button until the low tire pressure warning light blinks three times.
- Stop the vehicle in a safe place and turn the engine switch off and engage the parking brake.
- Adjust the tire inflation pressure recommended on the tire placard located on the door panel.
- Sit in the driver’s seat, close all doors, and turn the engine switch to ON. Do not start the engine but make sure that all other controls are off (headlights, heater/air conditioning, rear defogger etc.).
- Press and hold down the TPMS RESET button until it blinks three times (approximately 15 seconds).
- The low tire pressure warning light should go out once reset is complete after approximately 15 seconds of confirming correct inflation pressures have been restored to all tires or new tires have been installed and manually learned via Tire Pressure Monitor Learn Mode Switch or TPMS Reset button (if equipped).
Turn the ignition key to the “OFF” position and remove the key.
- Turn the ignition key to the “OFF” position and remove the key.
- The system is now reset. If you see the TPMS warning light, repeat the reset procedure.
The system is now reset.
After step *, the system is ready to be calibrated. If the system does not calibrate, drive the vehicle for a few minutes and then park it with the tires inflated to the recommended pressures.
If you’ve done everything correctly, you should receive a message that your TPMS has been successfully reset.
With the guide above, you should be able to reset your sensors easily and get your TPMS to function properly. However, it should be noted that reset procedures may vary depending on your Mustang’s model. If you are unable to fix the issue on your own, don’t hesitate to contact your trusted mechanic.
