Tire Pressure Sensor: Notes
CAUTION:
The use of tire sealants is strictly prohibited for vehicles equipped with the Tire Pressure Monitor (TPM) system. Tire sealants can clog tire pressure sensors.
CAUTION:
Be sure to reinstall tire valve caps, or dirt or moisture could get into the valve core and cause air leakage. Use only the original valve cap. If any other valve cap is used, it may corrode or melt, and become extremely difficult to remove.
NOTE:
The average life of the grommet of the tire pressure sensor is approximately 5 years, at which time it must be replaced. If valve is leaking air, but it is less than 5 years old and the grommets are in good condition, retighten valve nut to 35 INCH lbs. (4 N.m). Whenever the tires must be replaced, replace grommets for tire pressure sensors as well.
NOTE:
If the tire pressure valve sub-assembly is going to be replaced, make a note of the 7-digit number (transmitter ID) before installation, as it cannot be seen after sensor is installed. See Fig 1. Whenever a new sensor is installed, it will need to be registered in the tire pressure monitor ECU.
