Since I bought my 98 C5 a few months ago, about half the time the air pressure gauge on the front left tire either takes far longer to turn on and show pressure, or most of the time does not show anything and sometimes shows "PSI XXXXX" I went thru the "retraining" of the sensor and that did not seem to change anything. I am thinking that just that sensor is going (battery ?) but I do get a warning often in the display console that says "Service Tire Pressure system" ( or something close to that). Would you get that warning if just one sensor is bad or is that saying the whole system is having problems ? The other three sensors always work and am debating if I should spent the $125 per sensor and get the front left replaced ? I am assuming its a double sided tape connection or small bolt on that the local tire dealer can change or is this a dealer only thing ? Talked to two local tire dealers and they have changed plenty of tires with the sensor on them, but never had to replace one. Thanks for any idea's !

Dad, Thanks for the prices and URL to neri, I had guessed someone must rebuild them, but never found a site as my guess is that's its just a $2 internal battery that goes bad. Local dealer wants $134 for them, they said they are always in stock as they sell alot of them.. Guess I am not the only one that has problems. Gee I like the prices much better on the newer sensors ! Thanks for the info, that one is my next project for next week. Tedd

I read that there are no batteries involved. They generate power from the rotational motion (piezoelectric) to transmit to the car computer.

I thought that I had also seen the 10 year lithium battery also. That's what bugs me, paying out $140 because of a $2-$5 battery that you can probably buy at the local drug store. I take it when I replace it, I will have to go thru all the "retraining" of the sensor also ? Thanks.

You're both right about the lithium battery. Here is an article I found online. The piezoelectric device must be used to sense the pressure, not generate power for the transmitter:
Tire telltale. Yaw sensors are far from the only silicon-based sensors on today's cars. Peel back the tires on the new C5 Corvette or Chrysler Prowler, and you'll find micromachined pressure sensors integrated into the tire valve stems mounted to the alloy wheels. Developed by Schrader Electronics (Antrim, N. Ireland) the remote tire pressure monitoring system (RTPMS) gathers inflation information on the fly and transmits the data to a receiver in the car for display on the dash.
It uses a version of the model NPP-301 pressure sensor from Lucas Novasensor (Fremont, CA). Containing an ultra-small Silicon Fusion Bonded piezoresistive chip in a plastic, surface-mount package, the sensor produces a voltage output that is linearly proportional to the input pressure. Engineers at Schrader incorporate the sensor into an injection-molded plastic housing which also contains an ASIC, a radio transmitter section, a centrifugal switch, and a lithium battery, all potted for durability.
Begin driving the vehicle and the centrifugal switch places the RTPMS in "driving mode" in which pressure readings are gathered every 30 seconds and transmitted every 15 minutes. Should a rapid pressure change occur, the system increases transmissions to 30-second intervals as well. Driving mode contrasts with "stationary mode" in which the system wakes up every 15 minutes to take pressure readings, transmitting to the receiver once an hour. Engineers chose these discrete information gathering and transmission routines as a way to maintain performance while obtaining a ten-year battery life.
In the US, RTPMS broadcasts its bitstream of pressure data at 315 MHz, a frequency set aside by the FCC for on-car telemetry systems. In Europe, the favored channel is 433.92 MHz.
Accuracy is claimed to be ±2% full scale between 0 and 50C with a resolution of 1 psi. Still, the biggest engineering challenge wasn't designing a system to gather pressure data, but rather transmitting it. "You don't normally think about designing an RF transmitter that whirls around in a wheel at 60 mph and must transmit through a steel lattice--effectively a Faraday cage--to a receiver which is partly shielded by a metal body, now do you?" says Alastair Johnston, RTPMS marketing manager at Schrader. "It took us five years to develop the system, and it was definitely loads of fun." in article jK%ic.40852$G_.21...@nwrddc02.gnilink.net, Tedd Riggs at teddri...@NSverizon.net wrote on 4/25/04 8:54 PM:

Interesting article ! Sounds like the piezoelectric also switches the battery on. I got a response back right away from NeriCreations.com and he said the problem for sure sounds like a dying battery. Only thing I am not sure is what to do. Neri wants $ 67.22 (with 2 day shipping), but if I go that route, I have to go to a tire place twice, once to pull the old sensor and replace with a regular tire valve and then again when I get the sensor back, has to be pulled again to install the fixed sensor. Am wondering how the prices work out for: $67 for fixed sensor and the cost to break down the tire twice. $147 for a new sensor and break the tire down once.
Will have to do some checking on this one, too bad Neri does not have a core charge so you could just get a refurbished Sensor and then send your old one back after you swap them.

Tedd, Maybe you can help me. I bought a '98 C5 with a new tire pressure sensor installed. I need to "retrain" that sensor. How do I do that? Is this something I can do from the dash or will I need a special tool? Thanks, Mike

If the local dealer is nice, sometimes you can borrow one from them. Some of the Higher Tech Toy stores have them and also check in the fishing department of a sport store as they are used to pull up "hidden treasures"

Tedd, Thanks for the magnet idea (two individual magnets worked). But, it didn't solve my problem. The system recognized the sensor (I was told the sensor is new), but the system still doesn't get a reading from that tire. What receives that signal? Could that be the problem? Any ideas?
Thanks again, Mike

John, Do the other tire sensors work OK ? If they do, that rules out the expensive part which is the central radio receiver for the sensors. Sensors are picked up by the code and frequency they transmit on as they are just small radio transmitters. So more then likely a bad sensor. I was told by the dealer that even if the battery is almost dead, it will still transmit its signal saying "hey I am here" but not enough power to read the piezoelectric sensor and send that out. Second thing that will kill the sensor is if you or someone ever used something like "fix-a-flat" in those spray cans. That stuff will gum up the inside of the gauge and stop it from reading pressure changes. The dealer also suggested just letting most of the air out of the tire, then overfilling it to around 40 pds, let the air out again and then fill it with the correct air pressure. He said sometimes the sensor will become "unstuck" by doing that. If your horn beeps, then the main receiver is working, if it does not beep or all 4 sensors are dead, then you have a expensive main receiver to replace. Both local dealers said they have never had to do that.
Dumb question, but you are driving when you check the sensor right ? It will not give a reading if the car is just sitting, the system is turned on once the tire starts turning. Mine come on at most about 1 min later at speeds above 25 mph.
If those things don't work....then about the only thing left is to get a new sensor. Both my local dealers always carry them in stock as they said its not to uncommon that after 4-5 years they have to be replaced, he said most will last at least 6 years, but has had a number of 97/98 owners needing new ones.

Thanks again Tedd, It helps to know that the main receiver is not the problem. I will try to let the air out and over pressure and re adjust air. Maybe it will help. If not, I have a "bad" spare sensor that I can send in for repairs (thanks to the great guys here in the group, I know where).
Thanks again, Mike

Dad, You mean those basic little 3/4 inch (about) ones will work ? I thought you had to have a two pole magnet that was fairly strong. If those things will work, will make my job cheaper.

Yep, did it last night on the new one to see if they work. The washer is about 1/4 thick 1 3/4 OD X 3/4 ID. I first used a pair of stick magnets that are 7/19 X 7/8 X 2 that I got from Lowe's for hanging prints for the building trades. Formed them into a "v" and set them over the stem.

I cannot believe this. Went to the dealer to get the tire pressure sensor replaced (large dealer with about 10 work bays) and they said they cannot change it because it is to fragile and they don't have anything to break tires down that large. But they do not seem to have a problem installing new tires for you ! Checked with the local tire shop and they say they do this all the time on vettes and will charge $17.50 for it and that includes retraining the sensor. Weird !
