TPMS Reset
TPMS warning light stuck on? Sensor dead? We diagnose, replace, and reprogram your Tire Pressure Monitoring System so you're alerted to low pressure before it becomes a problem.
What Is TPMS?
TPMS stands for Tire Pressure Monitoring System. It's required by law on all vehicles sold in Canada since 2008.
TPMS uses small battery-powered sensors mounted inside each wheel. These sensors measure tire pressure and transmit readings to your vehicle's computer. If pressure drops below a safe threshold, a warning light appears on your dashboard.
The system is designed to alert you before low pressure becomes dangerous. Under-inflated tires can overheat, wear faster, reduce fuel efficiency, and increase the risk of a blowout.
When the TPMS light comes on, it's telling you something important. Ignoring it defeats the purpose of the system.
Why Your TPMS Light Stays On
The light can mean several different things. Here's how to tell them apart.
Low Tire Pressure
One or more tires are under-inflated. This is the most common reason. Check pressure with a gauge, inflate to spec, and the light should turn off.
Temperature Drop
Cold weather reduces tire pressure by roughly 1 PSI for every 10°C drop. A sudden cold snap can trigger the light even if you didn't have a leak.
Dead Sensor Battery
TPMS sensors have a 5–10 year battery life. When the battery dies, the sensor stops transmitting, and the light stays on regardless of pressure.
Faulty Sensor
Sensors can be damaged by impacts, corrosion, or water ingress. A faulty sensor transmits incorrect data or nothing at all.
System Not Reset After Tire Change
After tire installation or changeover, the TPMS system needs to be reset. If this step is skipped, the light stays on.
Why You Shouldn't Ignore the TPMS Light
Safety Risk
Under-inflated tires can overheat and blow out at highway speed. TPMS is your early warning system.
Faster Tire Wear
Low pressure causes uneven tread wear, cutting tire life dramatically.
Worse Fuel Economy
Under-inflated tires increase rolling resistance, increasing fuel consumption by up to 3%.
Failed Safety Inspection
If your TPMS light is on during a safety inspection, your vehicle may fail.

Frequently Asked Questions
What is TPMS?
TPMS stands for Tire Pressure Monitoring System. It alerts you when tire pressure is low.
How long do TPMS sensors last?
Most sensors last 5–10 years, depending on driving conditions and battery life.
Can I drive with a faulty TPMS sensor?
Yes, but you won't be alerted to low tire pressure, which can be dangerous. We recommend getting it fixed promptly.
How much does TPMS sensor replacement cost?
Cost varies by vehicle and sensor type. Contact us for a quote specific to your vehicle.
Can I reset TPMS myself?
Some vehicles allow a simple reset via a dashboard button. Others require a scan tool. If in doubt, we can help.
Do I need TPMS on winter tires?
Yes — if your vehicle came with TPMS, winter tires should also have sensors. We can install and program them. Learn about seasonal changeover.
