Low Engine Oil Pressure - Camshaft Control Disabled
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.
Engine oil pressure has fallen below the threshold required for hydraulic camshaft phasing. The ECM disables variable cam control to protect the actuator and lifters.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
