Drive with caution — fix soon.
This code means the computer detected a general malfunction in the fuel rail pressure sensor circuit, so it can't reliably read fuel pressure. It's commonly caused by a failing pressure sensor, damaged wiring, or a poor connection, and occasionally by an actual fuel pressure problem. It's usually diagnosed by testing the sensor and circuit, then repairing the wiring or replacing the sensor.
$150 – $450
Varies by vehicle and root cause.
Short distances may be okay if the car runs normally, but be cautious since this affects fuel pressure readings. If it's stalling or barely starting, avoid driving far and get it looked at quickly.
Most repairs fall between $150 and $450. The fuel rail pressure sensor is usually the main part, and price varies with how accessible it is and whether wiring needs work.
It can be moderately serious because fuel rail pressure directly affects engine operation. While many cases are just a sensor or wiring fault, it's worth addressing promptly to avoid stalling or no-start issues.
Sometimes, yes. Most of the time it's the sensor or its circuit, but a mechanic should confirm that fuel pressure is actually within spec before replacing parts.
