P0193 Code: Fuel Rail Pressure Sensor Circuit High
🟠 Moderate severity · drivable
Yes, but the engine may run poorly or be hard to start — get it fixed soon.
What P0193 means
The fuel rail pressure sensor is sending a voltage higher than the normal range. This usually means an open circuit, damaged wiring, or a failed sensor. Because the computer can't trust the pressure reading, the engine may run rich, stall, or be hard to start.
Symptoms
- Check engine light on
- Rough idle
- Hard starting
- Stalling
- Poor fuel economy
Common causes
- most common: Faulty fuel rail pressure sensor
- common: Open circuit or damaged wiring
- less common: Short to voltage in the sensor circuit
- rare: Engine computer (PCM) fault
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Replace the fuel rail pressure sensor | Yes | $80–250 |
| Inspect and repair the wiring or connector | Yes | $20–100 |
Frequently asked questions
Can I drive with a P0193 code?
Usually yes, but the engine may run rough, stall, or be hard to start. Have it fixed soon.
What does a high circuit mean?
It means the sensor voltage is above the normal range, often from an open circuit, short to power, or a failed sensor.
How much does it cost to fix a P0193?
A new fuel rail pressure sensor is typically $80–250, plus labor if a shop does the job.
