TPMS Service
The tire pressure light speaks two languages. A light that comes on and stays solid means a tire is low right now. A light that flashes for the first minute and then stays on means a sensor itself has failed — usually its sealed battery, which cannot be replaced on its own. Either way, the diagnosis here is free: we read every wheel's sensor in minutes and tell you exactly which case you are in.
Which light is yours?
-
Solid — after a cold snap, or a slow leak Pressure drops about 1 PSI for every 6°C. The first cold morning of fall lights up dashboards all over Markham; a nail does the same thing more slowly. First move: free pressure check and top-up.
-
Flashes 60–90 seconds, then stays on That flash is the car reporting a sensor that no longer answers — dead battery (sealed, 5–10 year life), a missing sensor, or one never programmed. This is the $70 fix.
-
On after a tire change or rotation Wheel positions changed and the car needs a relearn. Some cars teach themselves after 20 minutes of driving; others need our tool. If we did the work, come straight back — sorting it is on us.
-
Comes and goes with the weather On in the cold morning, off by noon: a tire is sitting right at the warning threshold. Not a glitch — that tire genuinely needs air.
-
You are driving on the spare Most spares carry no sensor, so the light stays on until the repaired wheel goes back on. Normal — but do not let it train you to ignore the light.
-
Someone used tire sealant Sealant gums up the sensor's pressure port — readings drift, and the sensor is often finished. Tell us before we open the tire; it changes how we work.
Still on after a TPMS repair?
Replacing a sensor is not always the whole answer. An incompatible protocol, an incorrect or duplicate ID, an incomplete relearn, or a vehicle communication fault can leave the warning light on after parts have been changed. We read the system wheel by wheel, verify sensor type, frequency and ID, and find where communication breaks down—working from the cause instead of guessing at more parts. No one can promise the outcome before testing, but TPMS problems that resist the usual repair are exactly what we are equipped and experienced to handle.

How it works
TPMS work is walk-in. The diagnosis takes about ten minutes and costs nothing; if sensors do need replacing, four take 30–45 minutes. The cheapest time to do them is during a seasonal change-over — the tires are already off the rims.

Common questions
Will insurance deny a claim over missing TPMS?
Not for the missing sensors alone — TPMS is not mandatory in Canada. But a TPMS warning light that has clearly been ignored may be treated as evidence of poor maintenance, giving the insurer an argument to raise when assessing an accident claim.
Can you just replace the sensor battery?
No — the battery is sealed inside the sensor at the factory. When one dies at the 5–10 year mark the others are usually close behind, so many customers do all four in one visit and save the repeat labour. Replacing only the dead one is fine too.
Could my car have no sensors at all?
Yes — some vehicles use indirect TPMS, which infers pressure from wheel speeds through ABS. Those cars just need the reset button pressed after topping up the air. The free diagnosis tells you which system you have before anyone spends a dollar.
315 MHz or 433 MHz — which does my car use?
It depends on make and year, and you do not need to know: our programmable sensors carry both frequencies in one unit and take on the right identity when programmed to your vehicle. That is why one price covers nearly every car.
Why does Tesla cost more?
Model 3, Model Y and newer S/X switched from radio sensors to Bluetooth Low Energy around 2021. The BLE sensor is a different part at a different cost — $95 installed. After installation, it takes about five minutes of driving before the pressure reading appears on screen.
Does my winter set need its own sensors?
It is worth it. We clone your summer sensor IDs onto the winter set, so the car cannot tell the wheels were swapped — no relearn, no warning light, and the seasonal change-over becomes a quick wheels-off, wheels-on job. One set of sensors pays for itself in convenience over the years you keep the car.
Can you install tires or wheels if the direct TPMS sensors are not working?
If the vehicle came from the factory with direct TPMS, we require working sensors before installing tires or wheels. Vehicles with indirect TPMS do not need sensors added. We do not bypass the system for an additional charge or with a signed waiver; instead, we can replace, transfer or clone the sensors, or provide the tires or wheels uninstalled.
Is TPMS required by law in Canada?
No. Transport Canada never adopted the US mandate (FMVSS 138, in force there since 2008), and no province requires it either — Ontario's safety inspection does not check TPMS, and Quebec mandates winter tires, not sensors. Most cars sold here have it anyway because they share US-market engineering.
Can I drive into the US without working TPMS?
Visiting, yes: a Canadian-registered car is exempt from US equipment standards for stays up to a year, and no state makes a working TPMS a condition of driving. Moving there is different — to import and register a 2008-or-newer vehicle, US customs requires factory-equivalent TPMS installed first, with proof. Customers relocating to the US come to us for exactly that before the move.
