Technical Specifications: Genuine VOLVO Electronic Throttle Actuator Assembly 14523019Genuine VOLVO Electronic Throttle Actuator Assembly — Engine Speed Governor Stepper Motor Solution
The Genuine VOLVO Premium Heavy‑Duty Electronic Throttle Actuator Assembly (Part Numbers: 14523019 / VOE 14523019), also known as Electronic Governor Stepper Motor, controls engine RPM for VOLVO mechanical‑injection and common‑rail engines. Driven by digital pulses from V‑ECU (11381435), it adjusts fuel pump governor linkage via built‑in stepper motor, reduction gears and position feedback potentiometer. Replacing worn actuators restores precise throttle response and eliminates engine hunting or auto‑idle failure.
Core Technical Advantages
High‑Torque Stepper Motor: High‑density winding delivers fast response and stable holding torque under load fluctuations.
Hardened Steel Reduction Gears: Precision alloy gears with high‑temperature synthetic grease resist stripping and mechanical jamming.
Conductive Plastic Feedback Potentiometer: Real‑time position signal ensures closed‑loop accurate throttle control with zero calibration drift.
Die‑Cast Aluminum Housing: Vibration‑damped anti‑oxidation shell with IP65 sealing protects internal components from heat, fuel mist and humidity.

Critical B2B Procurement & Maintenance Guidelines
B2B Procurement Strategy
Long‑term heat and gear wear cause throttle control failure, disabling machine operation. Stock 14523019 for emergency fleet repairs. Cross‑sell with governor linkage parts and main wiring harness (14624788) for complete fuel control system overhaul.
Common Failure Symptoms
No engine RPM change with throttle dial, stuck low idle + governor communication fault codes
Erratic engine hunting (200‑400 RPM fluctuation) caused by potentiometer dead‑spots
Grinding/chattering noise from actuator due to stripped internal gears from binding linkage
Best Practice Overhaul Advisory:
Disconnect main battery before replacement to avoid ECU damage from voltage surges. Ensure fuel pump linkage moves freely without binding before installation. Complete factory‑required throttle calibration via diagnostic tool after mounting and harness connection.
