Fuel Rail Pressure Sensor Circuit Low Bank 1

Where it lives

For P0192, the circuit described runs through the sensor. The description of P0192 puts it on bank 1.

Check these first

• A short to ground on the fuel rail pressure signal wire
• A failed fuel rail pressure sensor on bank 1
• Low fuel pressure from a weak pump or clogged filter
• A leaking injector on bank 1
• A faulty ECM input

What to do next

1. Check rail pressure against the commanded value
2. Test the signal wire for a short to ground
3. Inspect the sensor connector and wiring
4. Replace the fuel filter if rail pressure is short
5. Replace the fuel rail pressure sensor if it reads low
6. Clear the code and retest
