Continuing to drive risks injury or major mechanical damage. Shut the engine off when it is safe to do so.
Engine Oil Pressure Out of Range
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 measured oil pressure is far outside the expected range for current engine speed and oil temperature - either too low (oil pump weak, oil level low, bearing wear) or anomalously high (relief valve stuck closed, blocked oil cooler).
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
