Engine Oil 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 ECU has determined that engine oil pressure is below the safe operating threshold. Caused by low oil level, worn oil pump, severe engine wear, or a stuck pressure relief valve. Continued operation can rapidly destroy the engine.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
