Engine Controller Implemented Fuel Delivery Pressure
The engine control module (ECM) detected an out-of-range fuel delivery pressure.
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 ECM is monitoring the fuel pressure and found that it’s either too high or too low, which can impact engine performance and emissions.
What the computer is actually seeing
The ECM expects fuel delivery pressure to stay within specific parameters; if it sees pressure below 300 kPa (44 psi) or above 400 kPa (58 psi), it triggers this code.
What a healthy reading looks like
Normal fuel delivery pressure is usually between 300 kPa and 400 kPa (44-58 psi).
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check wiring and connector for the fuel pressure sensor—look for broken wires or corrosion.
- 2Test fuel pressure with a gauge; compare the readings to expected values (300-400 kPa). If outside range, proceed accordingly.
- 3Inspect the fuel lines for leaks or blockages.
- 4Use a scan tool to check for other related codes; if multiple codes are present, address them before replacing parts.
Common causes
- Faulty fuel pressure sensor
- Fuel system blockage
- Weak fuel pump
- Leaking fuel lines
- Faulty ECM software

Frequently asked questions
Is it safe to drive with this code?
It's moderate; you can drive it but fix it soon to avoid performance issues.
Will this code come back after clearing it?
If the underlying issue isn’t resolved, yes it will reappear.
Why does this code appear with other fuel system codes?
They often point to a common fuel delivery issue, like the pump or sensor.
