I know this has been discussed a lot, but.... Some folks on this forum and others have said to take the Tire Pressure Sensors and put them in a pvc tube with one drilled and "installed" and pressurize the tube. Some have said that won't work because the monitors don't transmit until they are rotating and then centrifugal force turns the sensor on to transmit. On a C5 for each tire location you use a magnet to calibrate. So I suspect the magnet "pulls" the switch inside the tps to turn the transmitter on in lieu of rotation and centrifugal force turning it on. If I have that right. Anyone tried, or have an opinion on whether taking a pvc tube with ends caped and drill four holes and install the four tps and tape a magnet one over each tps to get them to transmit would work? I realize that would put a drain on the batteries in the tps longer term but in theory I wonder if this would work. I am wondering for track purposes where I will need to change tire wheel sets and its gets inconvenient multiple tps sets and having to reprogram when changing tires. I do realize there is another way to disable need for tps in the ecu with a race program setup. Don't want to go that route, at least not yet.

 

Good luck.

 

I"m with QCVette. I swap from a set of wheels/tires with TMPS and to a set without regularly. Not a big deal. When I put on the set without I hit reset and off I go. Put the set "with" back on when I get home again and it just works, no reprograming needed.

 

I like the idea of just resetting the DIC while running track wheels without TPMS. But will active handling still work, or must it be turned off?

Also, I recall reading something about a 15-20 minute window of time, after which the car insists on TPMS to be active. Is that only on C6 and newer?

 

My car didn't come with TMPS, being a z06, I turned the tire monitoring on in the BCM with a TechII so I don't know about anything other than a Z06. I know that none of the nannies in my car care if I have the wheels with TPMS on or not. Everything seems to work the same either way.

Your mileage may vary

 

Emptinest, That is what I was worried about and wondering. If Active Handling stays on or disables. I was at the tack this weekend so you beat me to the question. The other track car.

Sox0Fan, Thanks. Since I bought Toyo R888 which are street legal I will check it out before I go to the track next time with the C5.

 

I think having or clearing the TPMS message has no effect on active handling. I thought that active handling gets inputs from the steering position sensor, the wheel speed sensors, and the yaw sensor, the G sensor, but not from the tire pressure sensors. Perhaps one of the experts on the system can give a more detailed explanation.

The 15 to 20 minutes is only because if the TPMS sensors are dormant after being still for a while, it may take that long for the sensors to start transmitting. The first time the car does not see signals from the sensor after driving for a while, the car will generate the DIC message. That will occur in about 15 to 20 minutes when the car doesn't receive the sensor signals. After the message appears, press the reset button to clear the message. After that, each time you start the car, the DIC message will appear and need to be cleared with the reset button. When you put the wheels with the sensors back on, you may get the message at start up or until the sensors activate which could be as much as 15 or 20 miles.

 

A couple of weeks ago I went to Monticello Motor Club. I can attest to the fact that Active Handling remains on and "active" after no TPMS and hitting reset to the warning message.
