P0192 Code: Fuel Rail Pressure Sensor Circuit Low
🟠 Moderate severity · drivable
Yes, but the engine may run rough, stall, or be hard to start — get it fixed soon.
What P0192 means
The fuel rail pressure sensor is sending a voltage lower than the normal range. This often means a short to ground in the wiring or a failed sensor. The computer can't trust the pressure reading, so the engine may run rough, stall, or be hard to start.
Symptoms
- Check engine light on
- Rough idle
- Stalling
- Hard starting
- Reduced power
Common causes
- most common: Faulty fuel rail pressure sensor
- common: Short to ground in the sensor wiring
- less common: Damaged or corroded connector
- 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 P0192 code?
Usually yes, but the engine may idle rough, stall, or be hard to start. Fix it soon.
What does a low circuit mean?
It means the sensor voltage is below the normal range, often from a short to ground or a failed sensor.
How much does it cost to fix a P0192?
A new sensor is typically $80–250, and wiring repairs are usually $20–100.
