Fuel Volume Regulator Control Exceeded Learning Limit
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 ECU's adaptive correction of fuel volume regulator A has reached its learning limit. Indicates a long-term drift between commanded and actual rail pressure that could no longer be compensated.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
