gasspjældspositionsføleren

gasspjældspositionssensoren, often abbreviated as TPS, is a vital component in modern internal combustion engines. It functions as a potentiometer, translating the physical position of the throttle plate into an electrical signal. This signal is then sent to the engine control unit (ECU), providing crucial data for optimizing engine performance and fuel efficiency.

The TPS is typically mounted on the throttle body, directly linked to the throttle shaft. As the driver presses the accelerator pedal, the throttle plate opens, and the TPS rotates accordingly. The electrical resistance within the TPS changes in direct proportion to this rotation. The ECU interprets the resulting voltage output from the TPS to determine the driver's demand for engine power.

This information is then used in conjunction with data from other sensors, such as the mass airflow sensor and oxygen sensor, to precisely calculate the amount of fuel to inject and the optimal ignition timing. A malfunctioning TPS can lead to a variety of drivability issues, including poor acceleration, erratic idling, stalling, and increased fuel consumption. In some cases, a faulty TPS may even trigger a check engine light. Regular diagnostic checks can help identify and address TPS problems before they significantly impact vehicle operation.
