TPMS sensors

Toss the assembly in the trunk and program the TPMS. I've never tried this but was told it works great, when mine start going bad I will be trying this.

Each sensor must be programmed individually and in the correct sequence to learn it's location on the car. I don't see how that method could possibly work.

Is it true that the sensors have to be woken up from sleep by the wheel movement? Think this would be another reason why the sensors don’t stay connected when trying this tube method.

I'm not 100% sure but I know when I add air to a tire and wait about a minuet
or so the rcdlr updates the pressure without the car being moved. I will have to check on that.

Yes you are correct:

When the vehicle is stationary, the sensors internal shock sensor is inactive which puts the sensors into a Stationary state. In this state the sensors sample tire pressure once every 30 sec and do not transmit at all if the tire pressure does not change. As vehicle speed increases, the shock sensor pulses every wheel rotation, which puts the sensor into Rolling mode. The remote control door lock receiver receives and then sends the tire pressure and temperature data to the body control module (BCM). The BCM translates the data contained in the tire pressure sensor radio frequency transmissions into sensor presence, sensor mode, and tire pressure. Once vehicle speed is greater than 40 km/h (25 MPH), the sensors begin to transmit once a minute keeping the pressure data up to date.

correct. in fact i had to pump all my tyres up the other day. took about 5 minutes of driving to update the pressure info.

Like I said I never tried it so don't know if it will work, sounds like it won't.

Just looked up how to replace the battery and they can be replaced but holy hell. $4-$5 for a battery plus all the hassle of tearing it apart, re-soldering the battery, then buying the special silicon and plastic that won't mess up the sensor to re-mold the silicon and the plastic, or order oem sensors off Amazon for $6-$7 each.

I'm due to replace the two front tires, and was looking into the TPM Sensors issue, 'cause the two front ones failed after 12 years of ownership (one did some eight months ago and the other about 4 months earlier).

Your comment is great advice. Thanks!

I believe what they did was program them then put them in the pressure vessel together. They claimed it worked fine. Its been a while since I ran across it so I'm not sure where I seen it. I'm going to be trying this when mine stop working. Things are just getting out of hand expensive to get even the basics done on a car anymore. Personlly I may jusy say hell with it and push the little button every time I use the car. The led doesn't bother me because I can't even see it anymore! HA (i have in the past took the cluster out and made the bothersome led's go to sleep permanently.
