Fuel Pressure Regulator 2 Performance

High severity

What it means

The high-pressure fuel pressure regulator (volume control or pressure control valve on a direct-injection rail) is not maintaining commanded pressure. Often the rail-pressure sensor reading drifts away from the setpoint under load.

Is it safe to drive?

No — stop driving

This code can put the vehicle into limp or reduced-power mode. Avoid extended driving and have the vehicle diagnosed promptly.

Most likely causes

  • Pressure regulator worn or sticking

    high

    One of the most commonly reported causes for this code — check this first.

  • High-pressure pump weak

    medium

    A plausible cause — test and verify before replacing parts.

  • Rail pressure sensor drift

    low

    Less common, but worth ruling out after the more likely causes.
