2013-2020 Ford Focus-C346N Pre-Programmed Smart TPMS Tire Pressure Sensors

This Smart Sensor kit replaces the tire pressure sensors on the third generation Ford Focus, platform code C346. The sensors are pre-programmed for the Focus's 315 MHz Ford system, so they can be mounted and trained to the car without a programming step.

A Focus from this generation is now old enough that its original sensor batteries are running out, which shows up as a TPMS warning that will not clear even after the tires are set to the right pressure. The sensors are sealed, so a dead battery means a new sensor. These Smart One sensors install in the factory location and talk to the Focus's TPMS module the same way the factory parts do.

The sensors are tested to SAE J1205 and J1206 standards for temperature extremes and corrosion. Installation requires taking the tire off the wheel.

Training the sensors to a Focus

Ford uses a training mode rather than an automatic relearn. With the car off, the ignition is cycled and the brake pedal pressed in a set sequence until the horn sounds, which puts the system in training mode. Each sensor is then woken with a TPMS tool starting at the left front and going around the car, left front, right front, right rear, left rear, with a horn chirp after each one. A shop with an OBD TPMS tool can also do it through the diagnostic port.

Common questions

Does this fit a 2019 Focus? The Focus sold new in the US ended after the 2018 model year. If you have a 2019 or 2020 Focus that was imported, put your VIN in the order notes and we will confirm fitment.

Can I do the training without a tool? The training mode can be started without a tool, but each sensor needs a TPMS activation tool to wake it up.
