Vehicle Fit

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.


  • Brand New Throttle Position Sensor
  • Mounts to throttle body
  • Built to strict quality control standards
  • 100% electrically tested prior to leaving the factory

This part is not a factory replacement for 95 Toyota Avalon
This unit is supposed to have resistance across two of the lower pins with the position sensor at idle. This replacement sensor does not show the correct resistance. In fact it shows no connection whatsoever making it an incorrect replacement since the idle transition cannot be set correctly with this throttle position sensor.
