Genuine Toyota Sienna Throttle Position Sensor

The Throttle Position Sensor detects how far the throttle is opened to ensure smooth driving with a fuel delivery to airflow ratio that the engine computer can match. The sensor of the Toyota Sienna is positioned on the throttle butterfly spindle. The voltage signal is compared to other engine data many times each second. Thus, this helps the system decide how much fuel to inject during acceleration, cruising, or slowing. In current designs, the Throttle Position Sensor utilizes a non-contact Hall effect, inductive, or magnetoresistive technology. It works by reading changes in a magnetic field produced by a rare-earth magnet that is fixed to the spindle. Meanwhile, the sensing circuit remains stationary inside the electronic throttle control housing. The old style potentiometric with a physical brush and resistive strip is avoided, reducing wear and promoting feedback. A specialized closed Throttle Position Sensor can signal when the throttle plate is shut, aiding idle stability in the Toyota Sienna drivetrain. A failure of the Throttle Position Sensor may cause decreased fuel economy and performance limits, so replacement of the Throttle Position Sensor keeps a Toyota Sienna running as expected.
