TPMS-19 Tire Pressure Monitor Sensor Tool (TPMS Reset/Training) – 8C2Z-1A203-A – For Ford

Brief Overview

This TPMS sensor is a replacement sensor for tire pressure monitoring and is stated to be compatible with selected Ford, Lincoln, and Mercury vehicles. The sensor replaces older, defective, or damaged tire pressure sensors and has reference/part numbers TPMS-19 and 8C2Z-1A203-A.

The TPMS system monitors the air pressure in the tires and warns the driver if one or more tires have low pressure or if the system does not recognize a sensor. This sensor can be used when replacing a broken sensor, during wheel refurbishment, or when an old sensor's battery has died and it no longer communicates with the car.

The sensor is intended for installation on the front/rear, left/right according to the product information. After installation, the car normally needs to undergo a TPMS training/relearn procedure so that the car's control system learns which sensor is located at each wheel position: front left → front right → rear right → rear left.

Important: Always check that the part number, vehicle model, model year, and TPMS system match before purchasing. TPMS sensors can vary between markets, model years, and trim levels.

What is a TPMS sensor?

TPMS stands for Tire Pressure Monitoring System. A TPMS sensor is mounted in the wheel and sends information to the car about tire pressure and sensor status. If the pressure becomes too low, or if the car loses contact with the sensor, the TPMS warning light may illuminate.

On many Ford, Lincoln, and Mercury models, the TPMS sensor is located next to the valve inside the wheel. Since the sensors have built-in batteries, it's common for them to need replacement after a few years, even if the car itself is otherwise functioning normally.

When does the TPMS sensor need to be replaced?

• When the TPMS light is on despite correct tire pressure.
• When a sensor does not respond during TPMS training/relearn.
• When the sensor's battery is dead.
• When the valve or sensor is damaged during tire change.
• When the car displays a tire pressure sensor error message.
• When building an extra set of wheels and needing sensors for winter or summer tires.

Part Number & Compatibility

This sensor is indicated with the following references:

• TPMS-19
• 8C2Z-1A203-A

Always match the part number against the car's existing sensor or parts catalog before purchasing. Even if the car is included in the model list, there may be different TPMS systems depending on the market, model year, equipment, and wheel type.

Tip: If you are unsure – check the part number on the old sensor or compare with the car's registration/VIN-based spare parts information.

Note: The supplier text contains some lines where model names are missing or incompletely specified. Therefore, compatibility should always be confirmed against part number TPMS-19 / 8C2Z-1A203-A.

Installation and Important Checkpoints

TPMS sensors are normally mounted in the wheel at the valve. Installation usually requires the tire to be detached from the rim. Therefore, replacement is often done in conjunction with tire service.

To check before installation

• That the part number matches: TPMS-19 / 8C2Z-1A203-A.
• That the sensor fits the car's model year and market.
• That the valve/sensor is correctly installed and seals against the rim.
• That the wheel is balanced after disassembly/assembly if needed.
• That the car can be put into TPMS training mode after installation.

After installation, the car normally needs to relearn the sensor positions again with a TPMS activation tool.

TPMS training/relearn for Ford

The following procedure comes from the supplier text and is used on many Ford-based vehicles. Always check the car's manual if the procedure differs.

Step 1 – Activate training mode

1. Turn the ignition to OFF.
2. Press and release the brake pedal.
3. Turn the ignition from OFF to RUN 3 times, ending in RUN.
4. Press and release the brake pedal again.
5. Turn the ignition to OFF.
6. Turn the ignition from OFF to RUN 3 times, ending in RUN.
7. If training mode is activated correctly, the horn will sound once and the TPMS indicator will flash.
8. If the car has a message center, the text TRAIN LF TIRE may be displayed.

Step 2 – Activate front left wheel

1. Place the TPMS activation tool at the front left wheel, on the tire sidewall near the valve area.
2. Press and release the test button on the TPMS tool.
3. Hold the tool against the tire sidewall throughout the activation.
4. It may take up to approximately 6 seconds for the tool to activate the sensor.
5. When the horn sounds, the car's control system has recognized the sensor.

Step 3 – Continue in the correct order

Within approximately 2 minutes after confirmation for the front left, the next sensor should be read. Continue in the following order:

1. Left Front (LF)
2. Right Front (RF)
3. Right Rear (RR)
4. Left Rear (LR)

Step 4 – Complete the relearn

Once the last wheel has been trained, some vehicles will display TIRE TRAINING COMPLETE in the message center. On vehicles without a message center, a successful procedure is confirmed, according to the supplier text, by turning the ignition to OFF without the horn sounding.

If the horn sounds twice when the ignition is turned to OFF, it means, according to the product text, that the training procedure was unsuccessful and needs to be redone.

Tips for successful relearn

• Perform TPMS training on one vehicle at a time only.
• Maintain a minimum distance of approximately 3 feet / approximately 1 meter from other vehicles with TPMS sensors to minimize interference.
• Avoid areas with strong radio frequency interference.
• If the car or wheels have been stationary for more than 30 minutes, the sensors may enter sleep mode.
• Wake up the sensors by moving/rotating the wheels or driving/rolling the car briefly before training.
• Hold the TPMS tool against the tire sidewall throughout the activation, for up to approximately 6 seconds.
• Follow the wheel order exactly to avoid incorrect positions in the car's display.

Troubleshooting

TPMS sensor not responding

• Check that the sensor is the correct model for the car.
• Check that the TPMS tool is held in the correct position at the valve.
• Hold the tool for up to approximately 6 seconds.
• Roll the wheel/car if the sensor might be in sleep mode.
• Check that you are not too close to other TPMS-equipped vehicles.

Car does not enter training mode

• Repeat the ignition and brake pedal procedure slowly and precisely.
• Check that the ignition ends in the RUN position at the correct step.
• Check the car's manual – some models may have a different procedure.

Horn does not sound at a wheel

• The sensor may be the wrong model, defective, or incompatible.
• The sensor may need to be activated/woken up by rolling the wheel.
• The TPMS tool may be misplaced or have a weak battery.

Horn sounds twice when ignition is turned off

According to the supplier text, this means that the training procedure was unsuccessful. Start over from the beginning and follow the order carefully.

TPMS light still on after sensor replacement

• Check the tire pressure in all wheels.
• Check that all sensors are correctly relearned.
• Check that the correct sensor is in the correct vehicle.
• Read TPMS fault codes with a compatible diagnostic tool if the light persists.
