A failing TPMS sensor will usually let you know before it causes you a bigger problem. Look out for the following:
- Persistent TPMS warning light: A dashboard light that stays on even after your tyres have been correctly inflated is the most common sign of a faulty sensor.
- Intermittent warning light: A light that flickers on and off, particularly in cold weather, often points to a sensor with a dying battery.
- Incorrect pressure readings: If your dashboard shows pressures that do not match a manual gauge check, one or more sensors may be faulty.
- Warning light after a tyre change: Sensors can be damaged during tyre fitting, or a new wheel may need a sensor cloned or programmed to your vehicle.
- MOT advisory or failure: Since 2012, a non-functioning TPMS is an MOT failure on cars first registered from January 2012 onwards.
If your TPMS light is on, we recommend booking a diagnostic check as soon as possible. Driving on incorrectly inflated tyres increases fuel consumption, accelerates tyre wear, and reduces braking performance.
