Tire Pressure Monitor Sensor Assembly Dorman 974-049 - 1ATPM00041

This tire pressure monitoring system sensor assembly is a brand new, aftermarket sensor. It is designed to replace all original equipment manufacturers including:

  • Beru, Lear, Pacific, Schrader, Siemens, TRW


  • Fits any one of the 4 wheel assemblies
  • Replaces dealer part numbers: 42753STKA02, 42753STKA03, 42753STKA04
  • Sensor assembly consists of the following new components:
    • Tire Pressure Monitor Sensor (TPMS)
    • Attachment Screw
    • Valve Stem
    • Nickel Plated Valve Core
    • Gasket
    • Washer
    • Locking Nut
    • Valve Stem Cap
  • Built to strict quality control standards
  • 100% tested prior to leaving the factory
  • New two-piece sensor design allows valve stem flexing from 5 to 26 degrees helping to eliminate breaking

Typical reasons why the sensor should be replaced:

  • Valve stem type TPMS sensors require installation of new hardware whenever a tire is is changed
  • Valve leak
  • Seal leak
  • Battery in sensor becomes weak or dies (average battery life is 5 years). All sensors will eventually need to be replaced
  • Valve core snaps off
  • Recommended to replace TPMS hardware every time a tire is removed from the rim to prevent corrosion buildup and for mounting safety of the locking nut

This tire pressure monitoring sensor makes a great replacement and with the new 2 piece design allows the valve stem to be serviced separately!
