Engine Oil Pressure Sensor Voltage
Indicates an issue with the engine oil pressure sensor voltage.
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 computer is seeing a voltage from the oil pressure sensor that's too low or too high, which means it can't accurately read oil pressure in the engine.
What the computer is actually seeing
The computer expects the oil pressure sensor to produce a voltage between 0.5V to 4.5V based on the pressure detected; values outside this range trigger the code.
What a healthy reading looks like
0.5V to 4.5V corresponding to oil pressure 5-100 PSI.
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 engine oil level; it should be at the correct mark on the dipstick.
- 2Inspect the oil pressure sensor connector for damage or corrosion; repair if necessary.
- 3Measure the voltage at the oil pressure sensor with the engine running; it should read between 0.5V and 4.5V.
- 4If voltage is out of range, check the wiring for shorts or breaks; repair as needed.
- 5Replace the oil pressure sensor if the voltage is normal, but the issue continues.
Common causes
- Faulty oil pressure sensor
- Damaged wiring or connectors
- Insufficient oil levels or oil quality issues
Typical repair cost
$$

Frequently asked questions
Is it safe to drive with this code?
It’s drivable but should be fixed soon to avoid potential engine damage.
Will this code come back after clearing it?
It may return if the underlying issue is not resolved.
Why does this code sometimes pair with low oil pressure warnings?
Because an improper reading from the sensor can mislead the computer about actual oil pressure.
