Has anyone had to replace the tire pressure sensor if so what is involved in the reair. My light keeps coming on but all tire pressures are over 30 including the spare.

 

I replaced the battery, not the sensor.

 

You would need to either get a TPMS tester or go to a dealer/tire center to have them test the sensors. Usually the batteries in the sensor last for around 7 years. Depending on what they find you can either replace the bad sensor or replace all of them as they will continue to become defective. If the sensors are good then you may have the TPMS module problem which will have to be replaced. If it is a sensor they need to remove the tire and replace the sensor. Most tire dealers remove the tire from the rim , install the new sensor and re-balance the wheel/tire. A sensor costs between $20 to $60 each with tire removal and balance around $15-$25. By the way the TPMS battery is not replaceable , the whole unit needs to be replaced.

 

Thanks for the info. Very helpful

 

costco has TPMS sensors i think they are like around 50.00 installed for our vehicles.

 

I replaced one on my 07 Tacoma - uses same sensor as ES350 wheels. I used 2X4's and weight of the truck to carefully pry apart the tire from the wheel and stick my hand inside to remove and replace the TPMS sensor. I didn't have to figure out which sensor was bad as I was moving the sensor from a scratched up wheel to the replacement wheel. Chances are it's one bad sensor and you can replace one and move it to each wheel one at a time until you find the bad one.

 

Unfortunately Toyota and some other Asian car mfg. have made the relearn/programming process more difficult then necessary. You can go to a dealer or tire shop and get this done but if you want to invest in a few hundred dollars you can do it yourself. You need a TPMS tester to find the bad sensor. When you find it you need to do as suggested above and replace it. Once replaced you need to read the sensor serial number into the car PCM in order to store it and it's position on the car. Then you can reset it. There are also 2 frequencies which you need to determine and they are 315 mhz or 433 mhz. Some cars will learn automatically and some need to be programmed. Also you can buy cheap sensor testers for $20 and even $140 but these don't allow you to reprogram the car and turn off your TPMS light. In order to do that you need to spend at least $250 and can go up to $1500 for a unit. Pick your poison and do a little web surfin to see how the system works.

 

 

I have replaced one and last night I had another one start to go with a low battery indicated when I used my tester. My car is a 2010 and the batteries in the sensor last around 7 years but some last until 10. If the battery is going or gone no matter what you do you can't turn off the dash light. You can do it yourself or take it to a tire shop. The sensor is a 315mhz and is pretty common. A Lexus replacement runs between $35-$80 . The tire shop can test your prior to replacement. Some charge $10 to $20 to replace it because they remove the tire and need to rebalance it after they install the sensor. They also have to reset the car TPMS module to reflect the new serial number.

 

There’s so many different makes and models and generations it gets confusing to me because I’m sure different applications apply to different years
