TPM Inactive message
Drove the Boxster for about 45 minutes today and put it in the garage. I backed the car out in the driveway to wash it after about an hour and got a "TPM inactive" message and the tire pressure indicator was flashing. After a bit, the tire pressure warning indicator remained lit continually and no pressure readings are available. It is very hot today, nearly 90 degrees, and when I garaged the car some of the pressures were above 38 psi. Also, the temp warning light came on steady, not flashing, when I drove the car around the block. Anybody have experience with this?
