How to diagnose and fix P2262: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Ford F-350 · 2011–2019
The 6.7L Power Stroke turbocharger's variable geometry vanes stick from soot buildup, and the turbo actuator motor fails, causing limp mode and reduced power. Extended idle time and short-trip driving accelerate soot accumulation on the VGT vanes.
Common Symptoms
- Reduced power / limp mode
- Black smoke on acceleration
- Turbo lag worse than normal
- Check engine light
- Whistling or squealing from turbo
- Boost pressure low
How to Fix
Clean the VGT vanes if caught early. Replace the turbo actuator if the motor has failed. In severe cases, the entire turbocharger must be replaced. Regular highway driving helps keep the vanes clean through higher exhaust temperatures.

Volvo V60 · 2011–2018
Market note: the D4 diesel was sold in Europe and other non-US markets (the US-market V60 was gasoline/PHEV only), so this applies to European/RHD-market cars. The 190 hp D4 diesel (both the older 2.0L 5-cylinder D5204T and the later VEA 4-cylinder D4204T) commonly develops turbocharger wear, typically around 80,000-120,000 km (roughly 50,000-75,000 miles), and earlier if oil-change intervals are stretched or the car is used mostly for short trips. Worn turbine blades and failing shaft seals cause gradually reduced acceleration that develops into a marked power drop, black smoke from the exhaust under load, and whistling or metallic noises. On the variable-geometry turbo of the VEA engine, a sticking VNT actuator/vanes can also trigger boost-pressure faults and limp mode. This is a distinct failure from DPF clogging, EGR fouling, or crankcase-ventilation (PCV) issues, though a neglected turbo often coexists with those. Note: the diesel D4 was not sold in the US market.
Common Symptoms
- Gradual loss of power / weak acceleration
- Black smoke from the exhaust under load
- Whistling or metallic noise from the turbo
- Limp mode / reduced power warning
- Oil consumption or oil in the intake tract
How to Fix
Confirm with boost-pressure logging and a visual/shaft-play inspection of the turbo. Replace the turbocharger (single turbo on the 5-cylinder; variable-geometry turbo on the VEA 4-cylinder); clean or replace the VNT actuator where sticking vanes are the cause. Prevent recurrence with low-SAPS full-synthetic oil and shorter change intervals (≤15,000 km) plus periodic longer high-speed drives and a brief cool-down idle after hard runs.

RAM 2500 · 2007–2024
The Holset HE351VE variable-geometry turbocharger uses an electronically controlled actuator (the geartrain and control board that moves the vane sliding ring) that is a well-documented failure point, often before 100k miles. Soot and carbon buildup, rust/corrosion binding the vane arm, worn actuator gears, or a corroded circuit board (from coolant/water intrusion) cause the actuator to stop positioning the vanes correctly. The truck then either spools quickly but chokes at mid/high rpm or spools slowly with a big loss of low-end torque, and typically drops into limp mode. Owners on Cummins forums report repeat failures and note the unit must be scan-tool programmed to the specific turbo after replacement.
Common Symptoms
- Loss of power / limp mode
- Slow or no turbo spool
- Excessive turbo whistle or lack of boost
- Check engine light with turbo actuator codes
- Sluggish acceleration when towing
- Actuator gear grinding/clicking on startup
How to Fix
Replace the VGT actuator with a genuine remanufactured Holset unit (common OEM/service PNs for 2007.5-2012: 2837675 / 4034315HX / 4046534 / 4049828; later 2013-2018 trucks use the updated HE300VG actuator). The new actuator MUST be calibrated/aligned and programmed to the turbo with a Cummins-capable scan tool (wiTECH) or a pre-programmed 'corded' plug-and-play unit such as the BD Diesel corded HE351 actuator. If the vane mechanism itself is seized with soot the whole turbo may need replacement. Clean the vanes/EGR side and address coolant leaks that corrode the board to prevent recurrence.

Frequently asked questions
What does P2262 mean?
P2262 stands for "Turbo Boost Pressure Not Detected - Mechanical." This code means the engine computer commanded the turbocharger to make boost but the expected boost pressure was not actually detected, and it traced the shortfall to a mechanical cause rather than a sensor or electronic glitch. The computer compares commanded boost to measured boost, and when the turbo isn't physically delivering it, this code sets. You'll typically notice a clear loss of power, especially under acceleration or load. It generally points to a mechanical problem in the turbo, its plumbing, or the wastegate/boost-control hardware.
What are the most common causes of P2262?
The most common causes of P2262 are: Boost leak in intercooler piping, hoses, or clamps, Stuck, leaking, or worn wastegate, Failed or sticking turbocharger (worn bearings/vanes), Clogged or stuck variable-geometry turbo vanes, Faulty boost control solenoid or actuator, Restricted intake or exhaust flow, Disconnected or cracked vacuum/boost control lines. The specific cause varies by vehicle.
How much does it cost to fix P2262?
Repair costs for P2262 range from $450 to $4,000, depending on the vehicle and root cause.
