HE400VG Turbo for Cummins ISX15 / X15 | Replaces OEM 5459710 | Direct Replacement VGT | 2016-2025
The Diesel Power Source® HE400VG is a direct replacement VGT turbocharger for 2016-2025 Cummins ISX15 and X15 engines. This turbo replaces the factory Holset HE400VG (OEM part number 5459710, 6382093RX, 5358001, 5358454, and 5458936) with an upgraded design that uses forged machined compressor wheels (FMW), improved engineering to address known OEM weak points, and a brand-new electronic actuator (not remanufactured). Choose between the standard 67mm compressor (HE467VG) or the DPS-exclusive 70mm compressor (HE470VG) for applications above 500 HP.
Every DPS HE400VG turbo ships with no core charge, a new intake air temperature sensor, new gaskets, and installation hardware. Verify your ESN with DPS before ordering to confirm correct fitment for your engine configuration.
Important: This turbo does NOT fit HE451VE applications. The HE451VE uses a different compressor cover and actuator configuration that is not compatible with this turbocharger. If your current turbo is an HE451VE (OEM PN 2882112 or 3796351), see the DPS HE451VE turbo page instead.
Compressor Size Options: 67mm vs 70mm
| Turbo Option | Compressor | Max HP | Recommended Use |
|---|---|---|---|
| HE467VG (67mm) | 67mm inducer, 7-blade FMW | 550-625+ HP | Stock replacement, mild tuning, daily work trucks, fleet applications |
| HE470VG (70mm) | 70mm inducer, 7-blade FMW | ~675 HP | Builds over 500 HP, performance tuning, heavy hauling with increased fueling |
The 67mm compressor is the largest size available on the factory Holset HE400VG. The 70mm compressor is exclusive to Diesel Power Source® and is not available from OEM or other aftermarket suppliers. Both options use the same turbine wheel and share the same VGT housing and actuator.
Why Replace Both the Turbo and Actuator Together
Diesel Power Source® strongly recommends replacing the turbo and actuator as a pair. Installing a new turbo with an old actuator (or a new actuator with a worn turbo) can cause VGT calibration errors, reduced performance, and premature component failure. Each DPS HE400VG turbo ships with a brand-new, pre-calibrated electronic actuator specifically matched to the turbo for proper VGT control from the first startup.

Cummins X15 HE400VG Turbo Replacement Guide
The Holset HE400VG (OEM PN 5459710) is the factory variable geometry turbocharger used on Cummins X15 and ISX15 engines built from 2016 through 2025. Over time, these turbos wear due to heat cycling, electronic actuator failure, soot buildup in the VGT vanes, or bearing deterioration. When replacing a Cummins ISX15 / X15 turbo, it is important to choose a replacement that maintains full OEM VGT function while addressing the known durability issues in the factory design.
The Diesel Power Source® HE400VG is engineered as a direct bolt-on replacement with performance-minded upgrades including forged machined compressor wheels for improved airflow and durability, and a DPS-exclusive 70mm compressor option for builds exceeding 500 HP.
ISX15 / X15 VGT Fault Codes - Common Codes That Lead to Turbo Replacement
VGT actuator fault codes on ISX15 and X15 engines are frequently misdiagnosed as actuator-only failures. In many cases the underlying cause is a worn or sticking turbo combined with actuator overload. If your engine is showing any of the codes below, the turbo and actuator should be evaluated together before ordering replacement parts.
| Engine / ECM | Cummins Code | SPN / FMI | Meaning |
|---|---|---|---|
| ISX15 CM2250 | 2449 | 641 / 13 | VGT Actuator Controller - Out of Calibration |
| ISX15 CM2250 | 2387 | 641 / 7 | VGT Actuator Driver Circuit (motor) - Not Responding |
| ISX15 CM2350 | 1894 | 641 / 9 | VGT Actuator Driver Circuit - Abnormal Update Rate |
| ISX15 CM2350 | 2198 | 641 / 11 | VGT Actuator Driver Circuit - Root Cause Not Known |
| X15 CM2450 | 2449 | 641 / 13 | VGT Actuator Controller - Out of Calibration |
| X15 CM2450 | 6432 | 641 / 14 | VGT Actuator Controller - Special Instructions |
| X15 CM2450 | 4956 | 6713 / 13 | VGT Actuator Software - Out of Calibration |
| X15 CM2450 | 5177 | 6713 / 9 | VGT Actuator Software - Abnormal Update Rate |
| Most platforms | (varies) | 641 / 12 | VGT Actuator - Bad Intelligent Device or Component |
Code 2449 (SPN 641 / FMI 13) is the most common cross-platform VGT code - it appears on both CM2250 and CM2450 engines with the same meaning. Replacing only the actuator when this code is present often results in repeat failure. DPS includes a brand-new matched actuator with every turbo to break that cycle. For a full troubleshooting guide on these codes, see: X15 Turbo Actuator Codes - What They Mean and When to Replace
ISX15 / X15 Turbo and VGT Problems (Common Symptoms)
If you are experiencing any of the following on your Cummins ISX15 or X15, the factory HE400VG turbo (5459710) or VGT actuator may be failing:
- Low boost or underboost under load, especially on grades
- Slow spool or laggy turbo response compared to normal operation
- Excessive black smoke during acceleration or under load
- VGT actuator fault codes - SPN 641, 2449, 2387, 1894, 2198, 6432 (see table above)
- Whining, scraping, or unusual noise from the turbo
- Repeated boost-related check engine light events
- Increased EGTs at the same load and speed compared to previous readings
- Weak or inoperative Jake brake / engine brake
Because VGT actuator failures can mimic turbo failure (and vice versa), this turbo includes a brand-new electronic actuator to reduce the risk of repeat repairs. If you are replacing due to actuator-related fault codes, replacing both the turbo and actuator together is the most reliable repair path.
Fitment Verification Required: If your current turbo has BOTH of the following, this HE400VG turbo will NOT fit your application: (1) an elongated compressor cover, and (2) an actuator with two coolant ports. See the fitment verification image in the product gallery. If you are unsure, submit your ESN and our team will confirm the correct turbo for your engine.
Fitment
This turbo fits Cummins ISX15 and X15 engines on CM2250, CM2350, and CM2450 platforms (2016-2025). Engine build date and ECM platform must be confirmed via ESN before shipment.
