Common Symptoms and Trouble Codes Addressed by a New HE351VE Actuator
A failing HE351VE actuator or sticking vane system often shows up as a combination of exhaust brake issues, power loss, and VGT-related fault codes, indicating it's time for a replacement.
Typical Driver Complaints:
Reduced or inconsistent exhaust brake performance
Lack of power or sluggish acceleration
Turbo lag or inconsistent boost pressure
Check Engine Light (CEL) illumination
Limp mode activation
Related Diagnostic Trouble Codes:
P00AF: Turbocharger/Supercharger Boost Control A Module Performance
U010C: Lost Communication with Turbocharger/Supercharger Control Module
P0234: Turbocharger/Supercharger Overboost Condition
P0299: Turbocharger/Supercharger Underboost Condition
P0046: Turbo/Super Charger Boost Control Solenoid Circuit Range/Performance
Pre-Installation Check: How to Inspect Your Turbo for Binding Before Installing the New Actuator
Replacing an actuator on a mechanically stuck HE351VE turbo can overload and damage the new unit, so a quick mechanical inspection is highly recommended to ensure proper function and prevent premature failure of your new remanufactured Holset HE351VE actuator.
Diagnostic Steps:
Basic shaft and wheel check: Ensure the turbo shaft spins freely without excessive play or binding.
Vane lever / unison ring movement: Manually move the VGT vane lever (if accessible) to confirm smooth, full range of motion without sticking.
Alignment and calibration: After installation, proper alignment and calibration are crucial for optimal performance.
Quick Diagnostic Tips:
If the turbo vanes are binding, address the turbo issue before installing the new actuator.
Ensure all electrical connections are clean and secure.
Clear all fault codes after installation and perform a test drive.

Feature Comparison: This Reman HE351VE Actuator vs. Typical Budget/Import Actuator
| Feature | This Reman | Typical Budget/Import |
|---|---|---|
| Internal Hardware | New OE‑grade ball bearings and bushings for smooth, repeatable vane sweep. | Often reused or low‑grade hardware that can bind under heat and load. |
| Electronics Repair | Known weak components on the circuit board replaced with OE‑spec or better parts. | Minimal rework; may only clean or reflow existing components, leading to repeat U010C / P00AF codes. |
| Calibration | Actuator calibrated and tested on an HE351VE turbocharger for correct travel and exhaust brake function. | Some units shipped without proper VGT calibration, causing over/underboost and drivability issues. |
| Application Focus | Targeted to 6.7L Cummins HE351VE Freightliner and similar light/medium duty trucks. | Generic "one‑part‑fits‑many" offerings with looser tolerances and mixed fitment reports. |
| Support | Backed by a U.S.-based reman facility and technical resources for Cummins VGT systems. | Limited technical support or guidance on diagnostics and installation. |
