P01C2
Fuel Rail Pressure Sensor Circuit Intermittent/Erratic Bank 2
What it means
Intermittent signal from fuel rail pressure sensor on bank 2. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
