Most likely cause: One of the sensors in a tire is faulty - and often it is the spare, as it doesn't get looked at very often. Take it along to your dealer and get them to check the sensors are all working and powered.

Sounds like an indirect TPMS. These can be easily damaged by tire-mounting machines. If one or both are damaged, you can get dash light staying on. If they're not damaged, sometimes they just need a reset, especially if you don't change all tires at once. Indirect sytems test revolutions, not pressure. So it will sense a problem if 2 front tires have ...

If I read your question correctly the sensors have not completely failed yet. The device that read the sensors is showing that the batteries in the sensors are getting low. These batteries are small, the size of watch batteries. An inertial switch wakes up the sensors when the tire begins to roll. They are expected to last 6 to 10 years in normal use. So at ...

There are two basic types of systems, direct and indirect. You have an indirect system. Direct systems use a pressure sensor and transmitter for each wheel. They send pressure information from each wheel to a computer module on the car. Some of these systems provide real time pressure and temperature readings to the driver. Here is an example of one of the ...

Your first major red flag is "you'll fail inspection, but if you let us fix your car RIGHT NOW you'll get your sticker!" All joking aside (not so much a joke..), it's unlikely these would both go bad. I have a 2007 vehicle that has original valve stems with no corrosion/rot at all (not garaged, I'm in Natick). It's quite possible they just threw the rims ...

Make sure all tires are at the specified pressure. Locate the tire pressure monitor reset button Switch the key to the off position, turn the key to the on position and hold the TPMS reset button until the light shuts off.

It could be that you have a wheel sensor going bad in one of your rims. Also, when you say you "The tire pressure on all four tires is OK." ... are they over pressure? The light could come on if there is too much air in a tire just through expansion because it is getting warmer out. I'm not sure if this is viewable through a code reader on the Hyundai, but ...

The TPMS sensor in each wheel does not come with new tires, it a separate part. There are TPMS reseal kits that are available separately, see picture below. The TPMS sensor is to be resealed each time a new tire is installed. This is industry best practice. It is not always done. It appears this was not done when your tires were installed or the new seals ...

It depends on where the valve was leaking from. I would of asked to see the old TPM units if that's not what they showed you. If it was leaking around the schrader valve, it's possible they didn't replace the valve with a new one. This won't necessarily cause a leak but if the neoprene seal on the valve is damaged it can leak. It's also possible that the ...

If this is the part you are trying to replace: You can have it replaced. The cost of the part is under $5 from rockauto.com (I'm sure it's available at other places as well). It's called a TPMS Service Kit (Schreader part #:34000).

One other thing you might check is for radio frequency interference to the TPMS from a Bluetooth-equipped device in use in the vehicle. I personally encountered this situation when using my iPad w/Bluetooth in my 2009 Hyundai Sonata Limited turned on in order to 'wirelessly' transmit audio from podcast app playback to a little Bluetooth receiver which fits ...

Direct TPMS utilizes a small transmitter on each wheel. The device is activated by an inertial switch that turns on when sufficient wheel rotation speed is achieved. This transmitter sends pressure and temperature data to one or more receivers. These systems work well until the transmitters battery quits and then the whole transmitter must be replaced. ...

Things to consider when having TPMS service are the age of the sensors and the cost of replacement without a tire purchase. Some sensors are serviceable. The valve core can be replaced along with the battery and the "O" ring. Most models have a life expectancy of 7-8 years. Talk to the tire retailer and find out what they charge for a repair with out a tire ...

It's a o-ring seal that is replaced on the inside of the rim. If your not currently having tpms problems you should be ok as long as the tire installed does not damage the sensor. Many different types are out there band type ford, and valve stem type most common. Also it will need to be calibrated or recognized by the vehicle once installed. Like on chevy ...

I have encountered a similar problem in my Hyundai Sonata 2009 Limited where the Bluetooth signal from my iPad interferes with the TPMS operation. In this case, the TPMS fault light on the dashboard cluster illuminates as opposed to the low tire pressure warning light adjacent to it .... but it's easy to mistakenly confuse the two. Happened the first time ...
