TPMS Figure 4: Removing the tire pressure sensor locking clip. TPS strap and cradle Figure 3: Exploded view of the tire pressure sensor. the wheel starting 90 degrees from the sensor, moving away from the sensor. CAUTION: Do not infate the tire higher than the maximum pressure stamped on the tire sidewall. 5. Infate the tire to the pressure specifed on the vehicle certifcation label (located on driver door or door pillar). 6. Install the wheel and tire assembly. 7. Train the TPSs. See Training under Reset procedures. Figure 5: Removing the tire pressure sensor. with the hinge side of the sensor on the right side when viewed from the curb side (beauty side) of the wheel. The sensor has raised markings indicating how to position it. 2. Clean the area where the sensor and cradle are to be installed. Remove the adhesive tape liner from the cradle, and position the sensor and cradle into the wheel drop well 180 degrees from the valve stem. 3. Install the tapered end of the strap through the opening of the cradle on the hinge side of the sensor. Tis will position the worm gear on the locking clip side of the sensor. CAUTION: Steel wheels have a "high spot" along their circumference. Ensure the strap is positioned in the lowest spot possible for correct sensor and cradle retention. 4. While keeping the strap parallel with the wheel fange, position the worm gear one-half to one inch away from the sensor and tighten to 27 in.-lbs. (3 N.m). 5. Place the wheel on the turntable of a tire machine so that the tire pressure sensor is at the 6 o'clock position, and the valve stem and machine arm are at the 12 o'clock position. 6. Lubricate and mount the tire onto the wheel starting 90 degrees from the sensor, moving away from the sensor. 7. Infate the tire to the pressure specifed on the vehicle certifcation label (located on driver door or door pillar). 8. Install the wheel and tire assembly. 9. Train the sensors. See TPS training. ■ NOTE: While the TPS is available separately, the cradle and strap are only available as a kit. Tough there are several diferent strap kits available based on wheel diameter, all kits share the same base part number. Removal 1. Remove the TPS. WARNING: Te strap is under tension. Always use safety goggles or a face shield and gloves when removing the band/strap. Failure to follow these instructions may result in personal injury. 2. To remove a dealer-installed strap, go to the next step. To remove a factoryinstalled strap, perform the following. • Locate the strap buckle. Secure strap to wheel using duct tape on both sides of the buckle, about 0.98-inch from the buckle. • Using a large screwdriver and a twisting motion, unbuckle the strap. • Discard the strap. 3. To remove a dealer-installed strap, turn the worm gear screw until the strap is fully released from the worm gear. Discard the strap. NOTE: To aid assembly, mark the location of the cradle prior to disassembly. 4. Remove the cradle by inserting a screwdriver under the cradle and prying up. Installation 1. Position the sensor into the new cradle by inserting the hinge end of the sensor into the hook end of the cradle, and pushing the opposite end of the sensor down onto the cradle. Ensure the sensor is fully seated into the cradle (a "click" noise will be heard). CAUTION: Metal scrapers can damage the wheel. When removing the cradle adhesive strip residue, use only plastic or non-metallic scrapers. NOTE: Te sensor and cradle must be positioned 80 Quik-Link: 800-687-1557 ext. 19134 Information for this column comes fom Mitchell 1's "Tire Pressure Monitoring Systems Guide" for domestic and import vehicles through 2012.
