Fuel Rail Pressure Performance - Engine Off
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
After engine shutdown, the fuel rail pressure does not maintain the calibrated decay profile. Indicates injector leakage or check valve fault.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
