07 impala tire pressure?
So just yesterday the indicator for the tire pressure came on and i checked the psi and one was about 29 while the others were 32, i went to put some air in and now im getting a service tire monitor system? whats wrong?
Does the tire pressure warning indicator blink and then stay on solid along with the "Service Tire Monitor" message? If so, it's not the low tire pressure but one of the TPMS sensors probably stopped transmitting. The problem is that you can't tell which one it is without the service tool. If the warnings bother you (can't pass inspection in some states), consider a visit to the service department, any GM dealership.
Yes, it's the same on 2006 and up. If you can be sure it's just the TPMS sensor and which one (after performing the learn procedure while everything was working), you can just take it to a tire shop and get a new sensor put in. That would be less costly and time consuming than a visit to the dealership.
