They only had TPMS on the 97 due to the light coming on so much. The EBCM calculates the rotating diameter to determine if a tire is low on this system. They did not have many vehicles with this system on them. Now all the TPMS use pressure sensors in the tires.
So in as the tires wear or summer winter tires are changed the sensor needs reset...I like this much better than a sensor per wheel!! TPMS sensors are for the old and young and otherwise unwilling, not those who maintain their rides as we do!
97 GTP / new head gaskets / plugs and wires / 180 stat / U delete / 3" cat back to v-force / rebuilt S/T / cone filter......Family car, we're not station wagon people
