My 2007 Honda Odyssey has TPMS problem. Stupid system annoying dash light. My tires were getting bald and TPMS came up on the dash. TPMS were 6 years old is a good time to change the sensors with the new tires. Found a great deal online for 4 sensors for $75. Installation is free because I bought new tires. Installer register all 4 sensors with the TPMS meter. Plug meter to the OBD and turn the ignition to ON. He reset the car TPMS. Unplug the meter and start the car. TPMS on the dash went away and Flat Tire indicator came up (!). That was a good sign. I drove for 20 minutes + Flat Tire (!) went away but TPMS came back up again. I know the sensors are good because it came from a legitimate manufacturer warehouse. I went there to pick it up. Tech check the sensors with TPMS meter to make sure is compatible with my Odyssey. Could it be the car main computer? I am not going to Honda Dealer too expensive. Just would like to find out the answer. Thank You
Good TPMS Sensors from https://more-sensor.com or they also sells it on Amazon & EBAY Seller more-sensor. They are legitimate manufacturer warehouse. No China fake crap. The Tire guys is not TPMS expert. They did not deleted the old TPMS code. Left it in the system that is why TPMS was on. I'm in the neighborhood went to see manufacturer Tech. He fixed it for free. TPMS is off. 4 sensors for $75 included tax & America's Tire sells for $60 for one - $240 for four. You do the math.
Here's the thing you bought for very low price sensors you could very well be there in compatible with the system. They're very specific frequencies even in one particular manufacturer they use different systems even in different manufacturing months. You add possible incompatible sensors to a complex system like that you just kind of creating a rat's nest of analytical problems. If you want to fix TPMS cheaply forget the original system and buy those aftermarket ones that just screw on the end of your cap and you get a little device that you can read it inside the car on or some even work with your phone and they were quite well
Thanks Scotty I check my tires once a month. TPMS is dumb. I'll black tape over it.
