Ford Puma Tire Pressure Warning Light: Causes, Fixes, and Full Reset Guide

Keeping your Ford Puma’s tires properly inflated is essential for safety, fuel economy, and tire longevity. When the tire pressure warning light (TPMS) illuminates, it’s more than just a reminder — it’s an alert that your vehicle may not be operating at peak performance. Below, we break down every cause, fix, and reset method related to the Ford Puma TPMS system with step-by-step precision.

🔧 Understanding the Ford Puma TPMS System

The Tire Pressure Monitoring System (TPMS) in the Ford Puma constantly monitors the pressure inside each tire. If one or more tires fall below the manufacturer’s recommended PSI, or if the system malfunctions, an amber tire pressure warning light will appear on your dashboard.

Common Causes of the TPMS Light

• Low tire pressure in one or more tires
• Faulty or damaged pressure sensor
• Depleted TPMS sensor battery
• System calibration error after tire rotation or replacement
• Cold weather pressure drop

🟠 Step 1: Check and Adjust Tire Pressure

Before attempting a reset, verify tire pressure levels.

Always check the label on the driver’s side door jamb (B-pillar) for official tire pressure specs.

Pro Tip:

Inflate tires when cold — before driving or at least 3 hours after the last drive. Adjusting pressure while tires are hot can give false readings.

🔁 Step 2: Reset the TPMS Warning Light

Once all tires are properly inflated, follow the reset steps depending on your instrument cluster type.

For 4.2-Inch Display Models

1. Turn ignition ON (engine off).
2. Using steering wheel controls, navigate to Settings → Information → Tire Pressure.
3. Select Reset.
4. Hold the OK button until “System Reset Successful” appears.

For 12.3-Inch Display Models

1. Press the Menu button on the steering wheel.
2. Navigate to Settings → Vehicle → Tire Pressure.
3. Press and hold OK until the reset confirmation appears.

Drive your vehicle for at least 15 minutes above 20 mph (32 km/h) for the system to recalibrate.

🌡️ Step 3: Cold Weather and Tire Pressure Fluctuations

Cold weather is a common trigger for the Ford Puma TPMS light. Tire pressure drops approximately 1 psi for every 12°F (6.5°C) decrease in temperature.

⚙️ Step 4: TPMS Malfunction or Flashing Warning Light

If the light flashes for 60–90 seconds and then stays on, the TPMS has detected a fault. Common culprits include:

• Dead sensor battery (usually lasts 5–10 years)
• Broken or damaged sensor during tire installation
• Receiver module malfunction

Quick Diagnosis Options

Most tire shops offer TPMS scans for a small fee — far cheaper than guessing which sensor failed.

🔋 Step 5: Replacing a Dead TPMS Sensor

Each Ford Puma sensor contains a sealed lithium-ion battery that cannot be replaced separately. If it dies, you’ll need to install a new sensor unit.

After replacement:

1. Inflate all tires to factory pressure.
2. Reset the TPMS using the steps above.
3. Drive for 10–15 minutes for auto-learning to complete.

🧠 Step 6: Full System Reset (Last Resort)

If the TPMS light remains after all previous steps:

1. Disconnect negative and positive battery terminals.
2. Press the horn button and switch on headlights to drain residual power.
3. Wait 15 minutes.
4. Reconnect positive, then negative terminal.
5. Start the vehicle — the TPMS should reinitialize.

💨 Step 7: Persistent Air Leaks or Pressure Loss

If the light returns frequently even after resets:

• Inspect for tire punctures or valve stem leaks.
• Submerge the tire in water to detect bubbles.
• Use a tire plug kit for small tread punctures (not sidewalls).

Driving on underinflated tires affects performance and safety:

🧩 Step 9: TPMS System Limitations and Notes

• TPMS is not a replacement for manual checks — verify pressures monthly.
• Do not rely on the digital display for exact PSI readings.
• Avoid tire sealants, as they can damage TPMS sensors.
• If a temporary spare tire is installed, the TPMS light will remain on until the original wheel is refitted.
