This throttle position sensor or TPS switch is a new, aftermarket part. It is mounted to the throttle body and is used to monitor the position of the throttle. Once the position is determined, it sends a signal to the engine control unit (ECU) as an input to its control system. If the TPS switch goes bad this could cause poor/erratic running engine with little or no power. Many times your check engine light might be activated by a bad TPS switch. If a bad throttle position sensor is your problem, why not fix it now with this new replacement.

Throttle position sensor (TPS) switch specifications:

  • Mounts to throttle body
  • Replaces dealer part numbers:4874371, 4874371AC
  • Built to strict quality control standards
  • 100% electrically tested prior to leaving the factory

Your Engine size can usually be found on a white sticker in the engine compartment near the radiator. If needed, your VIN code is the 8th digit of your vehicles Vehicle Identification number.
