P0092 2014 GMC Sierra Code - Fuel Pressure Regulator Control Circuit High Voltage
Quick Answer
The P0092 diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a fault in the fuel pressure regulator control circuit, specifically detecting high voltage. Common causes include Faulty Fuel Pressure Regulator: The actual fuel pressure regulator may be faulty, causing high voltage in the control circuit, Wiring Issues: Damaged or corroded wiring in the fuel pressure regulator control circuit can lead to high voltage readings, ECM/PCM Malfunction: A malfunction in the engine control module (ECM) or powertrain control module (PCM) can also trigger this code. 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.

Code P0092 2014 GMC Sierra Description
The P0092 diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a fault in the fuel pressure regulator control circuit, specifically detecting high voltage. The fuel pressure regulator is responsible for maintaining a consistent and appropriate fuel pressure in the fuel system. In this case, the high voltage indicates an electrical issue within the circuit that controls the fuel pressure regulator. This can disrupt the proper functioning of the fuel system, affecting engine performance and fuel efficiency. If left unaddressed, it can lead to engine misfires, poor acceleration, reduced fuel economy, and potential damage to other engine components.
Common Causes of P0092 2014 GMC Sierra
- Faulty Fuel Pressure Regulator: The actual fuel pressure regulator may be faulty, causing high voltage in the control circuit.
- Wiring Issues: Damaged or corroded wiring in the fuel pressure regulator control circuit can lead to high voltage readings.
- ECM/PCM Malfunction: A malfunction in the engine control module (ECM) or powertrain control module (PCM) can also trigger this code.
- Sensor Malfunction: A malfunctioning fuel pressure sensor can result in incorrect voltage readings in the control circuit.
- Poor Electrical Connections: Loose or poor electrical connections related to the fuel pressure regulator control circuit can cause high voltage issues.
Symptoms of P0092 2014 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Engine Stalling: The engine may stall or have difficulty starting due to inconsistent fuel pressure regulation.
- Decreased Fuel Efficiency: The vehicle may experience a decrease in fuel efficiency due to improper fuel pressure regulation.
- Rough Idling: The engine may idle roughly or inconsistently due to fluctuating fuel pressure.
- Lack of Power: The vehicle may feel sluggish or lack power during acceleration due to inadequate fuel pressure.
How to Fix P0092 2014 GMC Sierra
- Diagnose the Issue: Use a scan tool to retrieve the specific DTC and perform a visual inspection of the fuel pressure regulator control circuit.
- Check Wiring and Connections: Inspect the wiring and connections related to the fuel pressure regulator control circuit for any damage, corrosion, or loose connections.
- Test the Fuel Pressure Regulator: Test the fuel pressure regulator to ensure it is functioning properly and replace if necessary.
- Check Fuel Pressure Sensor: Test the fuel pressure sensor to determine if it is providing accurate readings and replace if needed.
- Clear Codes and Test Drive: Clear the DTC from the vehicle's ECM/PCM and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0092 2014 GMC Sierra
