Low Pressure Fuel System Pressure - Too Low
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.
The low-pressure (lift pump) fuel pressure is below the expected value. Insufficient supply to the high-pressure pump leads to power loss and possible HP pump cavitation.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
