How to Reset the Tire Pressure Light (TPMS) on a Ford Crown Victoria

1. Turn the ignition off and leave the key in the ignition.
2. Press and release the brake pedal.
3. Cycle the ignition from off to on three times, ending in on, without starting the engine.
4. Complete the entry steps 1–6 within 60 seconds to enter the reset mode.
5. Train the sensors in clockwise order: left front, right front, right rear, then left rear.
6. Hold the TPMS tool against the tire sidewall opposite the valve stem, with the tool arrow pointing toward the rim.
7. Press and release the activation button until the horn sounds once within about 10 seconds.

• A TPMS training tool such as P/N 8C2Z-1A203-A is needed; it can be bought from any Ford dealer.
• Do not wait more than two minutes between tires, or the whole procedure must be repeated.
• A double horn chirp means repeat the procedure; if no single chirp, rotate the wheels at least a 1/4-turn and restart at Step 1.
