Understanding TPMS Malfunction
TPMS, or Tire Pressure Monitoring System, is a crucial safety feature in modern vehicles, including the Maserati Granturismo.
It continuously monitors the air pressure in your tires and alerts you if the pressure drops below the recommended level. However, TPMS malfunctions can occur due to various reasons, leading to inaccurate readings and false warnings.
Two common causes of TPMS malfunction in Maserati Granturismo are:
- Bad Batteries in Tire Sensors: Over time, the batteries in the tire sensors can fail, causing the TPMS to malfunction. These batteries typically last around five years, and once they start declining, they cannot be replaced individually. If one battery fails, others are likely to follow suit.
- Control Module Failure: Another possible cause of TPMS malfunction is a failure in the TPMS control module (TPMS ECU). This electronic unit is responsible for receiving and interpreting signals from the tire sensors. A software error or other issues can disrupt its functioning, resulting in inaccurate readings and warning alerts.
Potential Risks of TPMS Malfunction
Ignoring TPMS malfunction in your Maserati Granturismo can have severe consequences. The TPMS warning light is not just an annoyance; it serves as a crucial safety indicator. If you continue driving with low tire pressure without being alerted, it can lead to:
- Tire Failure: Low tire pressure can cause excessive heat buildup and tire failure, putting you at risk of a potentially dangerous blowout while driving.
- Poor Fuel Efficiency: Underinflated tires increase rolling resistance, which leads to decreased fuel efficiency. Ignoring TPMS malfunction can result in unnecessary fuel consumption and increased expenses.
- Uneven Tire Wear: Incorrect tire pressure can cause uneven wear on your tires, leading to reduced lifespan and the need for premature replacement.

Dealing with TPMS Malfunction
Now that you understand the risks associated with TPMS malfunction, it’s crucial to address the issue promptly. Here are the steps you can take to resolve TPMS malfunction in your Maserati Granturismo:
1. Diagnostic Scan
The first step is to visit your local Maserati dealership or a trusted mechanic equipped with a diagnostic scan tool. They will connect the scan tool to your vehicle’s TPMS system to identify the faulty component, whether it’s a sensor, control module, or antenna.
2. Purchasing a New Module
If the diagnostic scan reveals a faulty control module, you can consider purchasing a new TPMS module. However, before making the purchase, check with your dealership if they allow the use of aftermarket parts. Some places may only accept parts installed by their technicians.
3. Return Policy
Before returning the old module, ensure that the place where you purchased the new module accepts returns. It’s always recommended to clarify return policies to avoid any inconvenience.
4. Replacing Sensors or Antenna
If the diagnostic scan confirms that the module is functioning correctly, the next step is to replace the faulty sensor or antenna. You can find affordable sensors on platforms like eBay, but make sure to look for the Huf equivalent to ensure compatibility with your Maserati Granturismo.
5. Professional Installation
To ensure proper installation and alignment, it’s advisable to have the sensors or antenna replaced by a local tire shop. This option is often more cost-effective than relying on dealership services. Before installation, make sure to note down the sensor ID codes and their respective locations.
6. Verify with Dealership
After the replacement, take your Maserati Granturismo to the dealership to have them hook up the scan tool once again. This step ensures that the new components are functioning correctly and that the TPMS warning light is properly reset.
Understanding Tire Pressure and Maintenance
While addressing TPMS malfunction is essential, it’s equally important to understand the significance of tire pressure and regular maintenance. Here are some important points to keep in mind:
- Toe Settings: Improper toe settings can cause excessive wear on the inner walls of your tires. It’s crucial to have your Maserati Granturismo’s toe settings checked and adjusted by a professional to ensure even tire wear.
- Tire Inspection: Visual inspection is vital to identify any signs of tire wear or damage. Regularly check for wear markers, cords showing through, or baldness. Don’t solely rely on the TPMS; visually inspect your tires before every drive.
- Recommended Pressure: Refer to your Maserati Granturismo’s manufacturer recommendations for the ideal tire pressure. Insufficient or excessive pressure can affect your vehicle’s performance, safety, and fuel efficiency.
- Seasonal Tire Changes: If you switch between summer and winter tires, ensure that the appropriate TPMS sensors are installed. Consider using TPMS bypass devices for wheels without sensors to avoid TPMS malfunctions during seasonal tire changes.
TPMS malfunction in your Maserati Granturismo can be frustrating, but it’s crucial to address the issue promptly to ensure your safety and maintain optimal vehicle performance.
By following the steps outlined in this guide and prioritizing tire pressure maintenance, you can effectively deal with TPMS malfunctions and enjoy a smooth and worry-free driving experience in your Maserati Granturismo.
Remember, regular tire inspections, alignment checks, and proper tire pressure maintenance are key to preventing unnecessary TPMS malfunctions and ensuring the longevity of your tires. Stay informed, stay safe, and enjoy the thrill of driving your Maserati Granturismo with peace of mind.
