Code P0092 2017 GMC Sierra Description
The diagnostic trouble code P0092 on a 2017 GMC Sierra indicates that there is an issue with the fuel pressure regulator control circuit, specifically that the voltage is too high. The fuel pressure regulator is responsible for maintaining a consistent fuel pressure in the fuel system, ensuring that the engine receives the correct amount of fuel for optimal performance. When the control circuit voltage is too high, it can lead to erratic fuel pressure levels, which can negatively impact the engine's performance and fuel efficiency.
Common Causes of P0092 2017 GMC Sierra
- Malfunctioning fuel pressure regulator: A faulty fuel pressure regulator can cause the voltage in the control circuit to be too high.
- Faulty fuel pump: A malfunctioning fuel pump can also contribute to high voltage in the fuel pressure regulator control circuit.
- Wiring issues: Damaged or corroded wiring connections can disrupt the flow of voltage to the fuel pressure regulator, resulting in high voltage readings.
- ECM malfunction: A problem with the engine control module (ECM) can also lead to high voltage in the fuel pressure regulator control circuit.
Symptoms of P0092 2017 GMC Sierra
- Poor fuel economy: The vehicle may experience a decrease in fuel efficiency due to the inconsistent fuel pressure levels.
- Engine misfires: High voltage in the fuel pressure regulator control circuit can lead to engine misfires, causing rough idling or hesitation during acceleration.
- Check engine light: The illumination of the check engine light on the dashboard is a common symptom associated with this code.
- Loss of power: The engine may struggle to generate power, resulting in sluggish acceleration and overall decreased performance.
How to Fix P0092 2017 GMC Sierra
- Diagnose the issue: Use a scan tool to read the fault codes and perform a thorough inspection of the fuel pressure regulator, fuel pump, wiring, and ECM to identify the root cause of the high voltage in the control circuit.
- Replace the fuel pressure regulator: If the fuel pressure regulator is determined to be faulty, replace it with a new one to ensure proper fuel pressure regulation.
- Check the fuel pump: Inspect the fuel pump for any signs of damage or malfunction and replace it if necessary.
- Repair wiring issues: Repair or replace any damaged wiring connections to ensure a consistent flow of voltage to the fuel pressure regulator.
- Reset the ECM: Clear the fault codes from the ECM and reset it to ensure that the high voltage issue is resolved.
Cost to Fix P0092 2017 GMC Sierra
The cost of repairing the fuel pressure regulator control circuit high voltage issue on a 2017 GMC Sierra can vary depending on the specific cause of the problem and the labor rates in your area. However, as a rough estimate, the parts for this repair could range from $100 to $300, while the labor costs could be between $150 and $300. Keep in mind that additional diagnostic time may be necessary to pinpoint the exact cause of the issue, so it's advisable to consult with a qualified mechanic for a more accurate cost estimate. Labor rates at auto repair shops typically range from $80 to $150 per hour, but rates can vary based on location and the shop's expertise.
