Code result
P05FC
Cold Start Fuel Pressure Performance Bank 2
Moderate severity
What it means
During cold-start the ECU runs an elevated rail pressure on direct-injection systems for better cold spray atomisation. The pressure target on bank 2 is not reached within the calibrated time window - typical for a high-pressure pump that loses output when cold or a pressure regulator with cold-stickiness.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
