What causes P1230 on a Ford?

Failed low-speed fuel pump relay or resistor circuit Worn fuel pump unable to run on the low-speed circuit Corroded fuel pump wiring or ground Blown fuel pump fuse PCM driver fault for the low-speed circuit

How do I fix P1230 on a Ford?

Test fuel pressure on both pump speeds Swap the low-speed relay with a known-good identical relay Inspect pump wiring and grounds for corrosion Check fuse condition under load, not just visually Replace the pump if pressure drops only on low speed
