Hitachi 4614910 Throttle Position Sensor

The 4614910 throttle position sensor is a potentiometer-type feedback device mounted on the throttle motor assembly. It converts throttle valve angular position into a proportional resistance signal for the engine ECU. Designed for Hitachi EX200-5, EX300-5, and ZAX series hydraulic excavators equipped with Isuzu 6BG1 diesel engines. The sensor features a plastic and aluminum housing with integrated connector, engineered to withstand vibration, hydraulic fluid exposure, and temperature extremes typical in construction machinery. Direct replacement for Hitachi OEM part numbers 4614910 and 4614912. Compatible with multiple excavator models across the EX and ZAX product lines.
