Tpms
I have a 2005 C6 that has about 53,000 miles. The TPMS is driving me a little crazy. Every day when I start the car, one out of 4 tires will read as having 0 psi. Generally, it is not the same sensor each time. After I drive for about 10 minutes it will start to register correctly. Sometimes it will do this when the car has only been parked for an hour or so.
One specific sensor has a tendency to show a low pressure reading (6-8 psi low) but seems to correct itself suddenly after 10 minutes of driving.
The last time I put the car in for service, the dealer said that the mechanic noticed the issue and reset all 4 sensors. As I was driving away from the dealership, I noticed one whell was showing 0 psi. It regsitered correctly before I got home.
I have heard that the batteries in the TPMS units are supposed to be good for 10 years. These are the originals and only about 5 years old.
Is it time to replace all 4 of them?? If so, are there any TPMS sensors that are better than what GM offers?
Any other suggestions welcomed!

If the TPS readings are 'normal' after driving for a short while, everything may be fine. This is from my 2005 owner's manual:
"The Tire Pressure Monitor (TPM) System on your vehicle, uses radio and sensor technology to check tire pressure levels. Sensors, mounted on each tire and wheel assembly transmit tire pressure readings to a receiver
located in the vehicle. The TPM sensors transmit tire pressure readings once every 60 seconds while the vehicle is being driven and once every 60 minutes when the vehicle is stationary for more than 15 minutes. Using
the Driver Information Center (DIC), tire pressure levels can be viewed by the driver. The TPM system also uses the DIC to warn the driver when air pressure, in one or more tires, falls below 24 psi (164 kPa) or is above 42 psi (290 kPa). For additional information and details about the DIC operation and displays see DIC Controls and Displays on page 3-48 and DIC Warnings and Messages on page 3-53."
I suggest you read your owner's manual for more complete information. Good luck!

Thanks for the response.
I have read the owners manual (first step), and searched for other threads (second step), but was thinking that my experience was not normal. Based on your response....I am gathering that what I am seeing is normal? If so, I won't spend the money to replace the sensors.
Thanks,
Andy

Andy,
It sounds like your TPMS is not normal. When working correctly, they should transmit the last known pressure until the car is driven for several minutes. You probably need at least one sensor and should think about replacing all four. A convenient time to do this is when you are replacing tires. If it gets worse, I would not delay as these things can make the Corvette experience less enjoyable.
If I recall correctly, some early 2005 models had an older style sensor that has been superseded by the new style. Check with gene at GM Parts House.

Same problem here with one sensor. Dealer reset several times, tire dealer reset several times. Dealer claimed the problem was everything from the weather to my tint on the windows.( I didnt have tint at the time). Finally struck a deal with the dealer, I will pay for the new sensor if it does'nt fix the problem lets just change it. This dealer is very small, they gave me a sensor and sent me to the local tire shop, which changed the thing out. Guess what no more problems.

iwonder if he reset in the wrong sequence. I now and it is jumping from one sensor to the next you could a have a bigger issus then just a single sensor issue. if you were closer you could take my extra set of tires, wheels and sensors I have the tool to program and if it still does it then the issue is in the BCM. paul
