Oil Pressure Out of Range
The engine control unit detects oil pressure is outside the acceptable range.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The engine's oil pressure sensor is noticing that the oil pressure is too high or too low. This can happen if there's not enough oil, or if the oil pump is failing to circulate oil properly.
What the computer is actually seeing
The ECU receives signals from the oil pressure sensor that should indicate a pressure between 5 - 60 psi at normal operating conditions. If the pressure drops below 5 psi or exceeds 60 psi, a fault is set.
What a healthy reading looks like
Normal oil pressure is typically between 10 to 30 psi at idle and 25 to 70 psi at 2000 RPM depending on the engine specifications.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the engine oil level and condition. If low, add the correct oil and check for leaks.
- 22. Inspect the oil pressure sensor's electrical connector for looseness or corrosion.
- 33. Use a mechanical oil pressure gauge to verify actual oil pressure. Compare reading to the expected values.
- 44. If actual pressure is low, check for a faulty oil pump or clogged oil passages. If high, investigate potential blockage or sensor failure.
- 55. Clear the code and test drive the vehicle to see if the code returns.
Common causes
- Low oil level
- Faulty oil pressure sensor
- Failed oil pump
- Oil passage blockage
- Incorrect oil viscosity
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with this code active?
No, if the oil pressure is too low or too high, it can cause severe engine damage. Address the issue as soon as possible.
Will this code come back after repairs?
If the underlying issue is fixed and the system is reset, the code should not return. If problems persist, further diagnosis is needed.
Why does this code come with other SPNs?
This code often pairs with others related to lubrication and pressure systems as they can be interlinked in malfunction scenarios.
