I change all TPMS in my 5 wheels (including spare tire). All pressure is ok … When we read the pressure on computer, everything is ok. Spare tire is 28psi but it read -0.7 psi on the computer. We tried a lot of thing also a reset but the light still on and the error message still indicate a pressure problem with the spare. Could you help ?
Are these factory or aftermarket parts? And if you can, try changing them around, but since it is the spare it isnt a huge deal if you cant get it to work. Although it could always be a defective part and you need to just go and see if you can get it swapped out.
