trouble code po193

P0193 - Fuel Rail Pressure Sensor Circuit High Input

Possible causes.

Excessive resistance in the circuit
- Low or no fuel
- Wiring harness connector of the fuel pressure sensor
- Fuel Rail Pressure Sensor
- Fuel Pump

verify the fuel pressure with a gauge then with a scan tool look at the FRP PID and compare them, if they are more than 3 psi off, replace the sensor, especially if there are driveability symptoms.
