P2293 on RAM
Fuel Pressure Regulator 2 Performance
P2293 on RAM vehicles indicates fuel pressure regulator 2 performance. Au7o has documented this code across 2 RAM models — most commonly on 1500, 2500. This code means the engine computer has detected that the fuel pressure regulator 2 isn't performing as expected, so the system can't maintain the correct fuel pressure under varying conditions. On many direct-injection and high-pressure systems, regulator 2 controls the high-side fuel pressure, and the computer compares commanded pressure to what the fuel pressure sensor actually reports. When the measured pressure drifts too far from the target, it sets this performance code, which can cause hard starting, rough running, hesitation, reduced power, or stalling. Causes typically include a faulty regulator or high-pressure pump, a fuel delivery restriction, or a pressure sensor problem. Typical repair costs on RAM range from $800 to $12,000, depending on the specific model and root cause.
Common Causes of P2293
- •Faulty fuel pressure regulator (regulator 2)
- •Failing high-pressure fuel pump
- •Faulty or out-of-range fuel rail pressure sensor
- •Clogged fuel filter or restricted fuel supply
- •Weak low-pressure (lift) pump feeding the high-pressure system
- •Leaking fuel injector bleeding off pressure
- •Wiring or connector fault to the regulator/pump
- •Air or contamination in the fuel system
P2293 on RAM by Model
RAM 1500(1 issue)
- EcoDiesel Fuel Pump Failure / Stalling2014-2022
The 3.0L EcoDiesel engine can experience fuel pump failures and stalling issues. The high-pressure fuel pump (CP4) is sensitive to fuel contamination and can fail catastrophically, sending metal debris throughout the fuel system. Water in fuel accelerates failure.
RAM 2500(1 issue)
- 6.7L Cummins CP4.2 High-Pressure Fuel Pump Catastrophic Failure2019-2025
The 2019+ RAM 2500 with the 6.7L Cummins diesel uses a Bosch CP4.2 high-pressure fuel injection pump that is prone to catastrophic self-destruction. The CP4.2 relies on diesel fuel for internal lubrication, and any contamination, water intrusion, or low fuel levels cause the pump to disintegrate, sending metal shavings throughout the entire fuel system. This contaminates fuel injectors ($500+ each x6), fuel rails, fuel lines, and the fuel tank, requiring a complete fuel system replacement costing $8,000-12,000+. The previous-generation CP3 pump was far more reliable. Multiple class-action lawsuits have been filed against Stellantis/Bosch.

What does P2293 mean on RAM?▼
P2293 stands for "Fuel Pressure Regulator 2 Performance." This code means the engine computer has detected that the fuel pressure regulator 2 isn't performing as expected, so the system can't maintain the correct fuel pressure under varying conditions. On many direct-injection and high-pressure systems, regulator 2 controls the high-side fuel pressure, and the computer compares commanded pressure to what the fuel pressure sensor actually reports. When the measured pressure drifts too far from the target, it sets this performance code, which can cause hard starting, rough running, hesitation, reduced power, or stalling. Causes typically include a faulty regulator or high-pressure pump, a fuel delivery restriction, or a pressure sensor problem. On RAM specifically, this code is documented across 2 models.
What causes P2293 on RAM vehicles?▼
Common causes on RAM: Faulty fuel pressure regulator (regulator 2), Failing high-pressure fuel pump, Faulty or out-of-range fuel rail pressure sensor, Clogged fuel filter or restricted fuel supply, Weak low-pressure (lift) pump feeding the high-pressure system. Specific causes vary by model and year — see the per-model sections below.
