P2262 on RAM
Turbo Boost Pressure Not Detected - Mechanical
P2262 on RAM vehicles indicates turbo boost pressure not detected - mechanical. Au7o has documented this code across 1 RAM model — most commonly on 2500. 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. Typical repair costs on RAM range from $450 to $1,900, depending on the specific model and root cause.
Common Causes of P2262
- •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
P2262 on RAM by Model
RAM 2500(1 issue)
- 6.7L Cummins VGT Turbo Actuator Failure2007-2024
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.

What does P2262 mean on RAM?▼
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. On RAM specifically, this code is documented across 1 model.
What causes P2262 on RAM vehicles?▼
Common causes on RAM: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2262 on a RAM?▼
