Oil Pressure Sensor Measurement Error
Indicates an issue with the oil pressure sensor reading.
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 oil pressure sensor should report how much pressure the engine oil is under. If it shows a value that's outside the normal range, the system believes there's a malfunction in the sensor or oil pressure itself.
What the computer is actually seeing
The engine control unit (ECU) expects a voltage signal from the oil pressure sensor between about 0.5 volts (for low pressure) and 4.5 volts (for high pressure), corresponding to 5-120 psi of oil pressure. Receiving a signal outside these expected voltages triggers the fault.
What a healthy reading looks like
Expected voltage from the sensor: 0.5V (low pressure) to 4.5V (high pressure); oil pressure typically should be within 10-80 psi at operating conditions.
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.
- 1Check the oil level and condition in the engine. Ensure it’s within the proper range and not dirty or burnt. Decision: Is the oil low or dirty? Yes: top-up/change oil. No: continue.
Common causes
- Faulty oil pressure sensor
- Wiring issue between sensor and ECU
- Oil pump malfunction
- Low oil level or oil quality
- Clogged oil filter

Frequently asked questions
Is it safe to drive with this code?
It's not recommended to drive without addressing the oil pressure issue, as it can lead to serious engine damage.
Will this code come back if I clear it?
If the underlying issue isn't fixed, yes, the code will reappear.
Why might this code show up alongside others?
Oil pressure issues can often be linked to multiple engine performance codes, as they all rely on adequate lubrication.
