What is the primary function of a throttle position sensor (TPS) on a Mercruiser engine?
The Throttle Position Sensor (TPS) on a Mercruiser engine monitors the precise angle of the throttle plate (butterfly valve) and sends this information to the Engine Control Module (ECM). The ECM then uses this data to adjust fuel injection timing, ignition timing, and idle speed, ensuring optimal engine performance and fuel efficiency across the entire throttle range.
