This code means the oil pressure sensor circuit is sending a higher-than-expected voltage to the computer, often indicating an open circuit, broken wire, or failed sensor. Because high voltage can correspond to very low or zero oil pressure on some systems, it's important to confirm actual oil pressure. Replacing the sensor or repairing the wiring usually clears the code once real pressure is verified.
$100 – $350
Varies by vehicle and root cause.
Only after confirming the oil level and pressure are okay. If the oil light is on or you hear engine noise, stop and check immediately, because high voltage can signal very low oil pressure on some systems.
Most repairs run $100 to $350. The sensor is usually cheap to replace, while tracking down an open circuit or wiring break can increase labor costs.
It's moderate but worth quick attention because it affects oil pressure monitoring. Usually it's an electrical fault, but a mechanic should verify real oil pressure before ruling out engine trouble.
It means the sensor circuit voltage is above the normal range, which often points to an open circuit or broken wire. On some vehicles it can also correspond to a reading of very low or zero oil pressure.
