P0087 on RAM
Fuel Rail/System Pressure - Too Low
P0087 on RAM vehicles indicates fuel rail/system pressure - too low. Au7o has documented this code across 2 RAM models — most commonly on 1500, 2500. This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode. Typical repair costs on RAM range from $50 to $12,000, depending on the specific model and root cause.
Common Causes of P0087
- •Clogged or dirty fuel filter
- •Weak or failing fuel pump (lift pump or high-pressure pump)
- •Faulty fuel pressure regulator or control valve
- •Restricted or leaking fuel lines
- •Faulty fuel pressure sensor
- •Air in the fuel system or running low on fuel
- •Worn high-pressure pump (direct injection/diesel)
P0087 on RAM by Model
RAM 1500(2 issues)
- TIPM (Totally Integrated Power Module) Failure2009-2016
The TIPM controls most electrical functions and commonly fails, causing erratic behavior. The fuel pump relay inside the TIPM is particularly prone to failure, resulting in no-start conditions. Horn honking randomly, headlights flickering, and wipers activating on their own are common symptoms.
- 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 P0087 mean on RAM?▼
P0087 stands for "Fuel Rail/System Pressure - Too Low." This code means the fuel rail or fuel system pressure has dropped below the level the engine's computer expects. The computer monitors a fuel pressure sensor and has seen pressure fall too low, meaning the engine isn't getting enough fuel — especially noticeable under acceleration or load. This is most common on direct-injection and diesel systems that run very high pressures. Symptoms include hard starting, stalling, hesitation, lack of power, and possible limp mode. On RAM specifically, this code is documented across 2 models.
What causes P0087 on RAM vehicles?▼
Common causes on RAM: Clogged or dirty fuel filter, Weak or failing fuel pump (lift pump or high-pressure pump), Faulty fuel pressure regulator or control valve, Restricted or leaking fuel lines, Faulty fuel pressure sensor. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0087 on a RAM?▼
