FUEL PRESSURE SENSOR 2 VOLTAGE ABOVE NORMAL
Fuel pressure sensor 2 has detected a voltage that is higher than normal range.
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 fuel pressure sensor measures how much fuel pressure is in the system, and if it reads too high, it means there’s an issue that could lead to poor performance or damage.
What the computer is actually seeing
The engine control unit (ECU) looks for fuel pressure sensor 2 voltage to be between 0.5V and 4.5V. If the voltage exceeds 4.5V, the ECU triggers the fault code.
What a healthy reading looks like
Normal fuel pressure sensor voltage should be between 0.5V (low) and 4.5V (high), indicating correct fuel pressure.
