Drive with caution — fix soon.
This code means the oil pressure sensor is reporting a value that's outside the expected range for current conditions. It's usually caused by a worn or failing oil pressure sensor or wiring issues, though it can sometimes reflect actual abnormal oil pressure. A mechanic will verify real oil pressure and then replace the sensor or repair wiring as needed.
$100 – $350
Varies by vehicle and root cause.
Only once you've confirmed the oil level and pressure are normal. If the oil light is on or the engine is noisy, stop and check before driving, since the sensor reading could be hiding a real problem.
Repairs usually fall between $100 and $350. The oil pressure sensor itself is typically affordable, but wiring repairs or further diagnosis can add to the cost.
It's a moderate concern. Most of the time it's a faulty sensor, but because it affects oil pressure monitoring, it should be checked promptly to be sure your engine is protected.
Yes, using oil that's the wrong viscosity or is badly degraded can shift oil pressure enough to set this code. Switching to the manufacturer-specified oil sometimes resolves it.
