A steady tire pressure light means at least one tire is low, so check all four with a gauge first. A light that flashes for about a minute and then stays on points to a sensor fault. Call Oklahoma City Tire Shop in Oklahoma City, OK to ask about sensor service for your vehicle.
A tire pressure light that stays on is the car telling you one or more tires have dropped below its threshold. A light that blinks for a minute or so after startup and then stays lit is usually reporting something different: the monitoring system itself has a fault, often a sensor that has stopped transmitting.
Oklahoma City Tire Shop works from 1444 SW 25th St in Oklahoma City. Business hours are Mon–Fri 8:00 AM – 7:00 PM, Sat 8:00 AM – 6:00 PM, Sun 10:00 AM – 2:00 PM. Phone ahead with the year, make and model so the sensor type can be confirmed before you drive over.
Why does the light come back after I add air?
Two causes account for most repeat lights. First, the tire you filled was not the low one, so the real leak is still going. Second, the sensor inside the wheel has a dead battery or has been damaged. These small units are sealed and, in general, are not serviced individually when the battery fails.
Check each tire cold with a gauge, spare included if your car monitors it. If every tire reads correctly and the light still returns, a slow puncture is ruled out and the sensor is the next suspect.
What happens to the sensors when tires are changed?
The sensor rides inside the wheel, behind the valve stem, so it is handled every time a tire is mounted or dismounted. Bring it up when you book new tires or a swap. Ask whether the quote covers checking each sensor, replacing the valve core or seal, and any relearn step your car needs afterwards.
Some vehicles relearn sensor positions on their own after a short drive. Others need a scan tool. The answer depends on the vehicle, which is why the make and model matter when you call.
Is it safe to keep driving with the light on?
If the light is steady, treat it as a low tire and deal with it today. If it is flashing and every tire gauges correctly, the car is still driving normally, but it has stopped warning you about pressure. A slow leak would then go unnoticed.
Any visible bulge, a tire that looks flat, or a vibration at speed is a reason to stop and call rather than keep going.
Why is my TPMS light flashing?
A light that flashes for roughly a minute at startup and then stays on usually signals a fault in the monitoring system, such as a sensor that is not responding. Check your tire pressures anyway, then call to talk through sensor service for your vehicle.
Do I need a new sensor with every new set of tires?
Not necessarily. A working sensor can usually be reused, but the valve stem seal and core are often replaced during the change. Ask the shop what your quote includes for sensors before you agree.
Can I reset the light myself?
Some vehicles have a reset button or procedure, and it only clears the light once pressures are correct. If a sensor has failed, the light will return, and a scan tool may be needed to find which wheel it is.
