TPMS Sensors in Whitecourt
Tire pressure monitoring (TPMS) sensor replacement, programming and warning-light diagnosis in Whitecourt.
Michelin says tires lose about 1 psi for every 10 °F (5.6 °C) drop in temperature. A tire set in a warm garage loses several psi on a −16 °C Whitecourt January night (Environment Canada 1991–2020 normals), which is often enough to turn on the low-pressure light.
If the light stays on after the pressure is corrected, or it flashes, a sensor may have failed. On most sensors the battery can't be replaced on its own, so the whole sensor is changed and programmed to the vehicle.
A second set of rims for winter tires needs its own sensors if you want the warning system to work all year. Sensors may need a relearn after a changeover.
Common jobs
- TPMS warning light diagnosis
- Sensor replacement and programming
- Sensors for a second set of rims
- Relearn after a changeover or rotation
Have this ready when you call
- Year, make and model of the vehicle
- Whether the light is steady or flashing, and whether it stays on after topping up
- Whether you have a second set of rims with sensors
Common questions
Why does my tire pressure light come on when it gets cold?
Pressure falls about 1 psi for every 5.6 °C (10 °F) drop, according to Michelin. Going from a 20 °C garage to a −16 °C morning lowers it about 6 psi, which can trigger the light. Top up the tires to the pressure on the door-jamb placard.
