P0193 2014 GMC Sierra Code - Fuel Rail Pressure Sensor Circuit High Input
Quick Answer
The Engine Control Module (ECM) uses the Fuel Rail Pressure (FRP) sensor to constantly adjust the high-pressure fuel pump's feed rate so that the ideal pressure is permanently maintained in the high-pressure section (between the high-pressure fuel pump and the injectors) by means of closed-loop control. Common causes include Low or no fuel, Faulty Fuel Rail Pressure (FRP) Sensor, Fuel Rail Pressure harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about P0193 2014 GMC Sierra Code
What does the OBDII code P0193 mean on a 2014 GMC Sierra?
The P0193 code indicates that the fuel rail pressure sensor is detecting a voltage signal higher than the expected range, suggesting an issue with the sensor or its circuit.
What are the common symptoms of code P0193 on a 2014 GMC Sierra?
Common symptoms include hard starting, engine stalling, reduced fuel efficiency, rough idling, and the illumination of the check engine light.
What causes the P0193 code to appear on a 2014 GMC Sierra?
Potential causes include a faulty fuel rail pressure sensor, damaged wiring or connectors in the sensor circuit, a malfunctioning fuel pump, or a fuel pressure regulator issue.
Can I drive my 2014 GMC Sierra with the P0193 code?
While the vehicle may still be drivable, it could experience performance issues, and driving with this code for an extended period could lead to further engine or fuel system damage.
How do you diagnose the P0193 code on a 2014 GMC Sierra?
Diagnosis typically involves checking the fuel rail pressure sensor, inspecting the wiring and connectors, verifying fuel pressure readings, and utilizing a scan tool to monitor the sensor’s voltage output.
How do you fix the P0193 code on a 2014 GMC Sierra?
Repairs may include replacing the fuel rail pressure sensor, repairing or replacing damaged wiring or connectors, or addressing issues with the fuel pump or pressure regulator.
Is a P0193 code related to low fuel pressure on a 2014 GMC Sierra?
No, the P0193 code specifically indicates a high input signal from the fuel rail pressure sensor, which typically points to an electrical issue rather than low fuel pressure.
How much does it cost to fix the P0193 code on a 2014 GMC Sierra?
Repair costs can vary but typically range from $100 to $400, depending on whether the issue is with the sensor, wiring, or fuel system components.
Can a dirty fuel filter cause the P0193 code on a 2014 GMC Sierra?
A dirty fuel filter is unlikely to cause this specific code, as P0193 relates to the electrical circuit of the fuel rail pressure sensor rather than fuel flow restrictions.
Do I need to replace the fuel rail pressure sensor to fix the P0193 code?
Not always. While a faulty sensor is a common cause, the issue could also stem from wiring problems or other related components, so a proper diagnosis is essential.
