Johnson & Evinrude Outboard TPS (Throttle Position Sensor) 

Throttle Position Sensors (TPS) tell your ECU exactly how far the throttle is opened—critical for smooth idle, crisp acceleration, and correct fuel delivery on EFI/DFI outboards. If your engine hesitates, surges, idles roughly, or throws TPS-related fault codes, a worn or misadjusted TPS is a common culprit. At OBParts.com, you’ll find direct-fit OEM and high-quality aftermarket TPS replacements for Evinrude & Johnson (E-TEC & Ficht) engines.
