Drive with caution — fix soon.
This code means the fuel rail pressure sensor is reporting pressure values that don't match what the computer expects, so the reading is considered out of range or implausible. It often points to a failing sensor or wiring problem, but it can also reflect a real fuel pressure issue such as a weak pump or restriction. Diagnosis involves comparing actual fuel pressure to the sensor reading before deciding on the fix.
$150 – $500
Varies by vehicle and root cause.
Short trips are often okay if the car runs normally, but stay cautious since it involves fuel pressure. If you notice hesitation, power loss, or stalling, avoid long drives and get it checked soon.
Repairs typically range from $150 to $500. A simple sensor swap is on the lower end, while fuel pump or fuel pressure problems can push the cost higher.
It's moderately serious because it can signal a real fuel pressure problem, not just a sensor glitch. Getting it diagnosed promptly helps prevent drivability issues or being stranded.
Not always. While the sensor or wiring is a common cause, this code can also point to low actual fuel pressure from a weak pump or clogged filter. A pressure test confirms the real cause.
