Ford Explorer 4.6L Engine Fault Codes P0358, P0581, P0307, and P0315 - Common Issues and Solutions

Model: Ford Explorer Fault Code: P0307 Posted: 2016-01-28 02:43

I'm experiencing multiple diagnostic trouble codes on my Ford Explorer with a 4.6L engine: P0358, P0581, P0307, and P0315. The vehicle shows intermittent misfires and rough idling, especially under load. Code P0358 indicates a faulty spark plug circuit for cylinder 7, while P0581 points to an issue with the fuel pump pressure sensor. P0307 suggests a misfire in cylinder 7, which aligns with the P0358 reading. P0315 reflects a starting system problem, possibly related to engine crankshaft position sensor or timing issues. I've already checked basic components like spark plugs and fuel filter, but the codes persist. I'm looking for guidance on next steps—especially whether coil pack #7 should be replaced or if there's another underlying cause.

P0316 is also present in some cases; it may indicate a starting system issue or initial engine run failure. Check the crankshaft position sensor and ensure proper grounding.

What year is your Ford Explorer? Start by checking coil pack #7—this is a common fix for P0358 and P0307 in 4.6L engines. Also verify fuel pump pressure sensor readings if P0581 persists.
