Bartec Tech Tips For Cold Weather & TPMS Sensors This Winter

05 October 2026

As temperatures begin to drop, workshops are likely to see more customers arriving with TPMS warning lights illuminated. Cold weather can cause tyre pressures to fall, so in many cases, the solution may be as simple as adding a little air. However, a warning light can also indicate an issue with the vehicle’s TPMS sensors or tyre pressure monitoring system. For technicians, the challenge is quickly identifying whether a vehicle simply needs a pressure adjustment or whether there is a genuine TPMS sensor or system fault.

Test TPMS Sensors Before You Start

This is where taking a moment to test before you touch can really pay off. Using your Bartec TPMS tool, you can quickly check TPMS sensor data and establish exactly what is happening with the vehicle. That could be a consistent pressure drop across all four tyres, a slow leak in a single tyre, a weak TPMS sensor battery or a sensor that is no longer responding.

Testing the TPMS sensors first removes much of the guesswork from the job. If tyre pressure is the only issue, technicians can confidently adjust the pressures and carry out the necessary reset or relearn procedure. If the test identifies a sensor or system fault, they can investigate further knowing there is a genuine issue to address.

Make Winter TPMS Jobs More Efficient

A quick initial check can also help workshops avoid unnecessary TPMS sensor replacements, saving both time and money for the workshop and customer. With colder weather bringing an increase in tyre pressure-related warning lights, an efficient TPMS diagnostic process can help keep jobs moving during a busy period. Testing upfront can save technician time, reduce comebacks and make seasonal TPMS visits easier to manage.
