P2263 on RAM
Turbo/Supercharger Boost System Performance
P2263 on RAM vehicles indicates turbo/supercharger boost system performance. Au7o has documented this code across 1 RAM model — most commonly on 3500. This code means the computer has detected that the turbocharger or supercharger boost system is not performing as expected, even though no single sensor circuit has failed. The computer compares the actual manifold boost pressure against the target it commanded and sets this code when they don't match for a sustained period. You may notice low power, sluggish acceleration, or limp mode. It signals an overall boost shortfall and usually points to leaks, a failing turbo/charger, or a control component rather than a specific wiring fault. Typical repair costs on RAM range from $200 to $4,000, depending on the specific model and root cause.
Common Causes of P2263
- •Boost/intake leak in piping, hoses, or couplers
- •Failing turbocharger or supercharger
- •Stuck or faulty wastegate or boost control actuator
- •Faulty boost/MAP pressure sensor
- •Clogged or damaged charge air cooler (intercooler)
- •Sticking variable-vane (VGT) mechanism on diesels
- •Faulty boost control solenoid or vacuum supply
- •Restricted air filter or intake restriction
P2263 on RAM by Model
RAM 3500(1 issue)
- 6.7L Cummins Exhaust Brake Actuator and VGT Turbo Issues2013-2025
The RAM 3500 6.7L Cummins equipped with the integrated exhaust brake system experiences failures of the VGT (Variable Geometry Turbocharger) actuator and exhaust brake solenoid. The exhaust brake uses the VGT turbo vanes to create backpressure for engine braking while towing. The electronic actuator (Holset HE351VE/HE300VG) sticks or fails due to carbon buildup, causing loss of exhaust brake function, reduced turbo performance, limp mode, and DTC codes P2263 or P006A. TSB 14-001-21 addresses VGT actuator calibration. Actuator replacement costs $800-1,500; complete turbo replacement is $2,500-4,000.

What does P2263 mean on RAM?▼
P2263 stands for "Turbo/Supercharger Boost System Performance." This code means the computer has detected that the turbocharger or supercharger boost system is not performing as expected, even though no single sensor circuit has failed. The computer compares the actual manifold boost pressure against the target it commanded and sets this code when they don't match for a sustained period. You may notice low power, sluggish acceleration, or limp mode. It signals an overall boost shortfall and usually points to leaks, a failing turbo/charger, or a control component rather than a specific wiring fault. On RAM specifically, this code is documented across 1 model.
What causes P2263 on RAM vehicles?▼
Common causes on RAM: Boost/intake leak in piping, hoses, or couplers, Failing turbocharger or supercharger, Stuck or faulty wastegate or boost control actuator, Faulty boost/MAP pressure sensor, Clogged or damaged charge air cooler (intercooler). Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2263 on a RAM?▼
