Code P0092 2017 GMC Sierra Description

High-pressure fuel is regulated by the high-pressure fuel pump actuator, which is a part of the high-pressure fuel pump. The high-pressure fuel pump actuator is a solenoid valve. The Engine Control Module (ECM) provides battery voltage on the actuator high control circuit and ground on the actuator low control circuit. Both circuits are controlled through output drivers within the ECM. When deactivated, both drivers are disabled. When activated, the high control circuit driver energizes the high-pressure fuel pump actuator, and the low control circuit driver Pulse-Width Modulates (PWM) the low control circuit to the ground. The ECM monitors the voltage on the circuits to detect a failure. The Diagnostic Trouble Code (DTC) will set if the ECM detects a short to voltage in the high-pressure fuel pump actuator low control circuit.

Frequently Asked Questions about P0092 2017 GMC Sierra Code

1. What does the OBDII code P0092 mean on a 2017 GMC Sierra?

P0092 indicates a high voltage issue in the fuel pressure regulator control circuit, which can affect the vehicle's ability to regulate fuel pressure properly.

2. What are the common symptoms of code P0092 in a 2017 GMC Sierra?

Symptoms may include engine misfires, poor acceleration, rough idling, decreased fuel efficiency, or the Check Engine Light being illuminated.

3. What causes the P0092 code to appear on a 2017 GMC Sierra?

Common causes include a faulty fuel pressure regulator, damaged wiring or connectors in the fuel pressure control circuit, or a malfunctioning powertrain control module (PCM).

4. Can I drive my 2017 GMC Sierra with the P0092 code?

While the vehicle may still be drivable, it is not recommended as it could lead to poor performance, engine damage, or reduced fuel efficiency.

5. How do I diagnose the P0092 code on a 2017 GMC Sierra?

Start by using an OBDII scanner to confirm the code, then inspect the fuel pressure regulator, wiring, and connectors for damage or corrosion. Perform a voltage test on the circuit if necessary.

6. How can a faulty fuel pressure regulator cause the P0092 code?

A faulty fuel pressure regulator can cause the control circuit to send or receive incorrect voltage signals, triggering the high voltage condition and the P0092 code.

7. What are the repair options for fixing the P0092 code on a 2017 GMC Sierra?

Repairs may include replacing the fuel pressure regulator, repairing or replacing damaged wiring or connectors, or reprogramming or replacing the PCM if it's faulty.

8. How much does it cost to fix the P0092 code on a 2017 GMC Sierra?

Repair costs can vary, but replacing the fuel pressure regulator typically costs between $200 and $500, while wiring repairs or PCM replacement may cost more.

9. Can a dirty fuel system cause the P0092 code?

While not a primary cause, a dirty fuel system can contribute to fuel pressure regulation problems. Cleaning the fuel system may help improve performance but wonâ€™t directly resolve the P0092 code.

10. How can I prevent the P0092 code from occurring on my 2017 GMC Sierra?

Regular maintenance, such as inspecting wiring, keeping the fuel system clean, and addressing any minor issues promptly, can help prevent the P0092 code from appearing.
