Engine Oil Pressure Sensor Input
Indicates an issue with the engine oil pressure sensor's signal.
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 oil pressure sensor is not sending the right signal to the engine control unit, which can mean there's either a problem with the oil pressure itself or the sensor has gone bad.
What the computer is actually seeing
The engine control unit is receiving a voltage signal from the oil pressure sensor that is outside of the expected range, indicating either low pressure or sensor failure.
What a healthy reading looks like
Normal oil pressure should typically be between 20-60 PSI (pounds per square inch) when the engine is running at normal operating 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's between the minimum and maximum marks on the dipstick. If low, top off with the correct oil grade.
- 22. Inspect the wiring and connectors for the oil pressure sensor. Look for frayed wires, corroded connectors, or loose connections. Fix any issues found.
- 33. With the engine running, use a scan tool to check the actual oil pressure reading. Compare it to the expected range of 20-60 PSI.
- 44. If the readings are low, test or replace the oil pressure sensor as needed. Verify if the wiring was the issue before condemning the sensor.
- 55. If the oil pressure remains low after the sensor replacement, check the oil pump functionality and confirm that there's no internal engine damage.
Common causes
- Faulty oil pressure sensor
- Low engine oil level
- Oil pump failure
- Wiring or connector issues to the sensor
- Engine wear causing low oil pressure
