The contact owns a 2007 Toyota Camry. The contact stated that while driving at various speeds, the tire pressure monitoring system warning light illuminated intermittently and eventually remained illuminated. The contact also stated that the failure occurred during extreme cold or humidity weather conditions. The vehicle was taken to the dealer where it was diagnosed that the tire pressure monitoring system needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

The tire pressure warning sensor is constantly illuminated on my dash board, despite having correct pressure in all tires on the car including the spare. It is a distraction. Took my car to the local Toyota deal and they inform me that the problem is traced to malfunctioning tire pressure sensors. Given the recalls on Toyota cars/trucks on calibration problems with tire pressure sensors and the fact that Toyota manufactures common parts for all vehicles such as these tire pressure sensors, I believe they are defective parts. My vehicle is a 2007 Toyota Camry with a V-6 engine manufactured in April 2007. Further compounding the problem is that Toyota representative attribute fault to the us government saying, "it's a government mandate for us to have these sensors on our cars". ridiculous.

2007 Toyota Camry. Consumer states problems with the steering wheel shaking while driving and the tire pressure sensor staying on. She also states that the sun visor flips down while the vehicle is in motion. The consumer stated after the tire pressure monitoring system was reset. But, it light illuminated again. The cd player was no longer working, even though it was replaced a year ago. Updated 01/12/11.

The contact owns a 2007 Toyota Camry. The contact noticed that the tire pressure warning light illuminated on the instrument control panel. He took the vehicle to a tire dealer and they replaced the cpms valves and all four tires. After the repair was made, the tire pressure regulator system light was still illuminated on the instrument control panel. He took the vehicle to a Toyota dealer, but they could not diagnose the cause of the failure. The Toyota dealer stated that the most likely explanation was because of an improper installation of the valve sensors. The vehicle has not been repaired because it has not been properly diagnosed. The failure and current mileages were 50,000.

Tire pressure monitoring system. Constant arguing/disagreement between dealer, me, and Toyota corporate about how this system works/is supposed to work. Dealer suspects my tire people damage the sensor. I am inclined to think either the system doesn't work properly/consistently or the dealer mechanic doesn't understand how to program the sensor codes. Dealer has contacted their Toyota support for clarification and learned lots from them because of my persistence and continued malfunctions. In a nutshell, the monitoring will not report a pressure problem unless the car has been driven 20+ miles in a single start. I only go over 20 miles in a single engine start about every three months. So, it seems like the monitoring system is not processing the available information in such a way that is reliable/meaningful. Further, if there is an accident, I don't know if this data is a recorded element in the black box feature of the car (how fast, seat belt use, other driving interpretations). If it is, how can that data element be considered as a potential factor (or not) if the monitoring system itself does cannot be trusted if driving less than 20 miles in any single engine start?? I do have different sensors in my summer and winter tires; my recently remounted winter tires (on their own wheels) worked fine until I drove over 20 miles last week. Back to the dealership, to argue about the monitoring system, receiver, sensors, and my tire guys.

While driving home from work I ran over a nail that punctured the driver's side rear tire, causing it to deflate slowly. When the tire was completly flat, and I noticed the shaking and sluggish handling, I pulled over to inspect. My tire pressure sensor did not work, and did not notify me of the problem. After getting back into the car the tire pressure sensor came on, but only while parked and with a completly flat tire. The money spent on this safety feature, in my opinion, was useless.
