| Toyota's have to be programmed in the cpu for the TPMS system to recognize them. Batteries good for about 5 years. Unlike others systems, Toyota does not indicate which tire has the problem. Can be any or all of them |

| That always drives me crazy. I basically own 4 cars between the wife and kids. All have TPMS but only one of them indicates the individual tire. What a clusterfuck system. |

No ethanol!
| Tire stores or repair shops can read the units, and they'll know which one(s) are low. If you're likely to keep car a long time, you can replace them all so the repairs are done once, and not repeating one wheel at a time as batteries about the same age give out together. My batteries went 11 years in a G8.

I know Ford sensors will transmit all the info but the computer in the car has to have that feature "turned on." My Mustang is a base model so that feature is flagged as "dumb mode" so all I get is a binary problem/no problem light/message. I'm into year 9 on my '13.

| That’s messed up. My 2021 Subaru tells what each tires psi is. It’s nice. |

| There are all different sensor types and kinds and very specific to your vehicle. It depends on year, make,model, wheel type(steel or alloy)rubber stem or metal and sometimes whether there is a sensor in the spare. Replacement sensors can be OEM or aftermarket. Some come pre-programmed and some need to be programmed or cloned. Not all cars have tire sensors in the wheel although all cars made after 2007 have to have some provision to let the driver know that the tire is low on air. Some cars rely on their wheel speed sensors to supply this information.

| Toyota / Lexus issue: Two years ago I drove about six months with an intermittent TMPS light that lit up the dashboard 'red triangle' panic light. Every time I visited the tire shop, it was off and they said to come back. It finally stayed on long enough for the shop to read it and charge me $80 to replace that sensor.
Last fall, the intermittent TMPS light lit up again. Time to play the game again, or just pay more and replace the other three sensors. |

My thoughts exactly. If they cant tell which sensor is bad or just a bad battery, I understand they cost $40.00 or more each, plus the mount and rebalance of 4 tires. Racket. I think I can just live with the light on as I have a good tire gage. That's more than I can say for the small tire shop that plugged the tire. 75 Pounds air pressure this last time and no gage on the guy. |

Para I find only a fragrance company by that name. Schrader seems to make some OEM sensors. They cant even leave a simple thing like tire pressure free from electronics. Really just want round rubber wheels which go down the road nicely. The sensors do give good service life considering what they endure. |

Initech’s headquarters burned down several years ago. That could explain it. Try the ones made by Initrode if you can’t find Initech units. -Rob

| Dang! I had no idea that there was a battery in the... TPS = Throttle Position Sensor. TPMS = Tire Pressure Monitoring Sensor. FWIW, there is a TPMS kit that can be had for about thirty bucks. Sensors are screwed into the valve stem cap and the receiver plugs into the lighter socket. It monitors pressure and temperature and gives a readout for each tire.

| TP MS (tire pressure monitoring system). I thought you meant a throttle position sensor. Generally with TPMS, the light on steady means a low tire (it is also possible for a faulty sensor to read low), a flashing light that turns on steady after a while is a lack of communication from one or more sensors. Any direct-measurement system (indirect systems, using the wheel speed input from the ABS, also exist) has an internal battery in the sensor, and they do go bad over time. My own Toyota (2009 Corolla) still has the originals. Two weeks ago I did have the light flash then turn steady on two occasions, but it hasn't repeated itself.

This is what mine does after the vehicle has been shut off. Flash a few times them steady light. And yes, I called the tire pressure sensor the TPMS. If 38supersig would have read beyond my acronym, he would have known. The sensors actually came about due to a Federal Law regarding vehicle roll overs from under inflated tires. TREAD Act. |

| Local tire shop should have a small device they can go around and check your sensors individually.

Now I am going to replace the tire. Both punctures out in the no repair zone. Driving on the Flea Market property is hazardous. So the bad tire lost a bunch of air when temps here dropped down. Blew it back up and its holding air now. The TPMS dash light is staying on now. A friends Rav 4 had a rear mounted spare on its door mount which went low air pressure. Her dash warning light came on. Pretty tech. I am starting to think my sensor may have a bad battery. What do you know of TPMS sensors?This message has been edited. Last edited by: David Lee,
