Need a refresher in how to program a TPMS valve? This video takes you through what you need to do, step by step.

You’ll need to program a TPMS valve if you’ve replaced the component due to a fault. Once it’s been installed correctly, the vehicle has to undergo a learning process. This is a fairly simple procedure, which you can complete with a Delphi BlueTech diagnostic tool.

In this video we’ll show you:

• The process of how to program and re-learn a TPMS valve, using a Nissan Leaf to demonstrate

• How to navigate the diagnostic tool

What is a TPMS valve?

TPMS stands for tyre pressure monitoring system. This measures tyre pressures from electric sensors that are inside the tyre valve and then sends that information to the vehicle’s computer. If it detects a change in air pressure, the system will alert the driver with a yellow/amber warning light on the dashboard.

Why does a TPMS valve need to be programmed?

Programming a new TPMS sensor is an essential step. Universal or “programmable” TPMS sensors need the correct information to function as they should. Out of the box the technician needs to programme them with the unique sensor data and what vehicle it is being fitted to. If this step is missed, the sensor won’t transmit any information to the computer.

What’s the difference between programming a TPMS sensor and ‘re-learning’?

When a TPMS valve is being replaced, the procedure isn’t completed until the vehicle has “re-learned” the component. This will ensure it works properly so that the whole TPMS system functions as it should.

This is different to programming a sensor, because in the re-learn step the vehicle’s computer is being told which sensors are in which tyre location so they’re correctly recognised.

Is it mandatory to have TPMS?

It became mandatory to have TPMS in the USA as long ago as 2007, in Europe on new cars from 2014 and since then trucks, trailers, buses and coaches have been added to that list. In July 2024 mini-buses, small trailers, pick-ups and vans have been added. To make sure the vehicle complies with regulations check the category for the vehicle being worked on.

How long does a battery last?

As TPMS became mandatory several years ago, and batteries last between 5-10 years expect to see many sensors now failing. Informing a customer that all sensors will need to be replaced and programmed may be the only option.

Why is a diagnostic tool needed?

We use the Delphi BlueTech diagnostic tool in the video. This is used to connect both with the sensor and the vehicle’s ECU and ensure the correct codes are communicated.
