Engine Oil Pressure Sensor Fault
The engine oil pressure sensor is reporting an out-of-range value.
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 monitors the engine's oil pressure and sends data to the computer, which needs the pressure to be between 5 and 60 PSI for proper lubrication. If the pressure drops too low or goes too high, it triggers the fault code.
What the computer is actually seeing
The engine control unit (ECU) reads the oil pressure sensor's voltage, which should vary between 0.5V (low pressure) and 4.5V (high pressure). If the reading is below 0.2V or above 4.8V, it logs a fault.
What a healthy reading looks like
Oil pressure should be between 5 PSI to 60 PSI when the engine is running; sensor voltage should be between 0.5V to 4.5V.
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 oil level and quality; fill or replace if necessary.
- 2Inspect the wiring and connector to the oil pressure sensor for damage or corrosion.
- 3Measure the oil pressure using a mechanical gauge; it should read 5 PSI to 60 PSI at normal operating temperature.
- 4Check the voltage at the sensor connector; it should be between 0.5V to 4.5V while running. If it’s out of this range, replace the sensor.
- 5If all previous steps are normal, consider testing or replacing the engine oil pump.
Common causes
- Faulty oil pressure sensor
- Oil level low or oil quality poor
- Wiring or connector issues to the sensor
- Oil pump failure
- Clogged oil passages
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with this code active?
It's not recommended to drive as low oil pressure can cause engine damage.
Will this code reappear after clearing?
If the underlying issue isn't fixed, it will likely come back.
Why does this code pair with other SPN codes?
Multiple codes can indicate general oil pressure issues or related sensor failures.
