Laminated Oil Pressure Sensor Fault
Engine oil pressure sensor is reporting erroneous data.
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 malfunctioning, giving readings that are too high or too low, which can affect engine lubrication and could lead to engine damage.
What the computer is actually seeing
The ECU expects oil pressure readings between 20-60 PSI at normal operating temperature, but it's receiving values outside of this range, indicating a sensor issue.
What a healthy reading looks like
Normal oil pressure during operation is typically between 25-65 PSI, depending on engine design and temperature.
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 engine oil level; ensure it is within the correct range.
- 22. Inspect the wiring and connectors to the oil pressure sensor for signs of damage, corrosion, or loose connections. Repair or replace as necessary.
- 33. Measure oil pressure manually using a mechanical gauge – values should be 25-65 PSI at normal operating temperature. If not, replace the oil pressure sensor.
- 44. If mechanical gauge shows correct pressure but code persists, replace the oil pressure sensor.
- 55. Clear the fault code and monitor for reoccurrence.
Common causes
- Faulty oil pressure sensor
- Wiring issue between the sensor and ECU
- Low oil level
- Oil contamination or incorrect type
- Faulty engine oil pump

Frequently asked questions
Is it safe to drive with this code?
It’s best to avoid driving until the issue is resolved to prevent potential engine damage.
Will this code come back after I clear it?
If the underlying issue is not fixed, it will likely return.
Why does this code appear with low oil pressure codes?
The sensor may be failing, giving incorrect readings, or there could be an actual low oil pressure issue in the engine.
