Fuel Pressure - Data Valid but Above Normal Operational Range
This code indicates that fuel pressure is too high.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The system is detecting that the fuel pressure is higher than normal. While the computer expects fuel pressure to be within a certain range, it's measuring values above that limit, which can lead to performance issues.
What the computer is actually seeing
The engine control unit is receiving a voltage signal from the fuel pressure sensor that equates to a fuel pressure above the predetermined normal range, typically above 60 PSI for most diesel applications.
What a healthy reading looks like
Normal fuel pressure range for diesel applications is usually between 45-60 PSI.
