Tire Pressure Monitor Sensor Assembly Dorman 974-049 - 1ATPK00042

These tire pressure monitoring system sensor assemblies are brand new, aftermarket sensors. They are designed to replace all original equipment manufacturers including:

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

Specifications:

  • Tire pressure monitoring system sensor assembly set of 4
  • Fits all 4 wheel assemblies
  • Replaces dealer part numbers: 42753STKA02, 42753STKA03, 42753STKA04
  • Sensor assemblies consist of the following new components:
    • Tire Pressure Monitor Sensors (TPMS)
    • Attachment Screws
    • Valve Stems
    • Nickel Plated Valve Cores
    • Gaskets
    • Washers
    • Locking Nuts
    • Valve Stem Caps
  • 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 sensors should be replaced:

  • Valve stem type TPMS sensors require installation of new hardware whenever the tires are changed
  • Valves leak
  • Seals leak
  • Batteries in sensors becomes weak or die (average battery life is 5 years). All sensors will eventually need to be replaced
  • Valve cores snaps off
  • Recommended to replace TPMS hardware every time the tires are removed from the rims to prevent corrosion buildup and for mounting safety of the locking nuts

These tire pressure monitoring sensors make great replacements and with the new 2 piece design allows the valve stems to be serviced separately!

One of the features says two piece design allows for the stem and sensor to be serviced directly. Does that mean that the tire can remain on the rim during replacement? If so what is the process?

BEST ANSWER: When first replacing the assemblies you must remove the wheel from your rim to ensure that the base is placed properly. After installation however depending on the reason for secondary replacement you may service them individually. In some cases if it is the valve stem you would not need to remove the tire from the rim.
