Hi-yo Silverado!
Chevy models feature two different kinds of sensors

SUBJECT VEHICLE: 2007-10 Chevrolet Silverado.
SENSOR IN TIRE? No (sensors/transmitters are installed in wheels).
RESET PROCEDURE? Yes.
SPECIAL TOOLS NEEDED? Yes (TPM Sensor Activation Tool J-46079).
When a 2007-10 Chevy Silverado is moving 20 mph or faster, the tire pressure monitoring system’s (TPMS) wheel-mounted tire pressure sensors transmit radio frequency signals to the Driver Information Center (DIC) every 60 seconds. The DIC displays individual tire pressures as well as their locations. The Remote Control Door Lock Receiver (RCDLR) receives and translates the data in each sensor transmission, then sends the tire pressure and tire location data to the DIC. The sensor’s pressure accuracy is 2 psi at temperatures from 14-158 degrees Fahrenheit.
There are two different kinds of TPMS sensors in use on 2007-10 Silverados — the clamp-in style and the snap-in style.
To remove an old sensor, follow these steps.
1. Raise the vehicle and remove the tire/wheel assembly.
2. Demount the tire from the wheel following the manufacturer’s instructions. Pay special attention to the following to avoid damaging the sensor.
• Place the sensor’s cap and valve on a dry, clean surface after removal. The cap is aluminum and the valve is nickel-plated to prevent corrosion. DO NOT substitute a cap or valve made of any other material.
• Position the bead braking fixture 90 degrees from the valve stem when separating the tire bead from the wheel.
• Position the mounting/demounting head so the tire iron (or pry bar) can be inserted slightly clockwise of the sensor body when prying the tire bead up and over the mounting/demounting head.
• Using a tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the outside of the wheel rim.
• Repeat for the inner bead.
3. If the sensor is the clamp-in style, follow the “clamp-in style” removal procedures. If the sensor is the snap-in style (see Figure 1), follow the “snap-in style” removal procedures.
Clamp-in style sensor removal
1. Remove the tire pressure sensor nut.
2. Remove the sensor from the wheel hole.
3. Remove the sensor grommet from the valve stem.
4. Follow the clamp-in installation procedures to replace the sensor.
Snap-in style sensor removal
1. Remove the TORX screw (Figure 1, item 3) from the tire pressure sensor (Figure 1, item 2) and pull is straight off the tire pressure valve stem (Figure 1, at top).
2. Remove the tire pressure valve stem by pulling it through the rim.
3. Follow the snap-in installation procedures to replace the sensor.
The next step is to install replacement sensors by following these steps.
