• Q: How to replace the TPMS Sensor on 2008 Cadillac STS?

  A: To replace the Tire Pressure Indicator Sensor, raise the vehicle on an appropriate support first of all. Take off the tire/wheel assembly from the vehicle. Make sure to put the sensor's cap and valve on a clean surface as the cap is in aluminum and the valve is nickel plated in its finish so as to avoid corrosion; These should not be substituted with any other materials. When detaching the tire bead from the wheel, the bead breaking fixture should be set 90 degrees to the valve stem, and the tire iron or pry bar must be inserted a bit clockwise of the sensor structure whilst prying the tire bead. Employ the tire machine for circling the tire/wheel assembly in a clockwise fashion while the transmitting the tire bead to the outside of the wheel rim and vice versa. Remove the tire from the wheel, making sure to remove all of the tire sealant residue from the inside surfaces. Secondly, take out the tire pressure sensor nut and sensor. Clean any dirt on the grommet sealing area then place the sensor inside the wheel hole, facing the air passage away from the wheel. Make sure that all parts that are replaced are the part number and the use of any thread locking compound, lubricants, or sealants are applied as specified since these can impact final torque and operation of the components. While supposing the sensor body to be parallel with the inside wheel surface, install the sensor nut and tighten it until 7 N.m (62 lb in). Before reinstalling the tire, place the mounting/dismounting head 180 degrees from the valve stem and 45 degrees counterclockwise from the point where the bead transitions from the tire bead to the wheel rim; reinstate the tire/wheel assembly clockwise while moving the tire bead to the side of the wheel rim, then do that for the external bead. Mount the tire to the tire wheel. Notice that service replacement tire press sensor is return in OFF mode, and a tire/wheel assembly must be spun greater than 32 km/h (20 mph) for at least 10 seconds to close the internal roll switch. Lastly, mount the tire/wheel assembly onto the vehicle, and lower it along with learning the tire pressure sensors.
