99 Ford F350 P0352 Fault: How to Identify and Fix the Bad Coil Pack
How can I diagnose which coil pack is faulty when my 1999 Ford F350 displays DTC P0352? The code indicates a misfire in cylinder #2, which is typically associated with the passenger-side second front coil pack on a 5.4L engine. To confirm whether the coil pack itself is defective or if there's an issue with wiring, start by inspecting the coil connector—many models use snap-fit connections that can become loose over time. A reliable diagnostic method is to swap the suspect coil pack with a known good one; if the P0352 code clears after swapping, it confirms the original coil was faulty. If the code persists, the issue may lie in the wiring or ignition system.
The P0352 code points to cylinder #2 — likely on a 5.4L engine. This coil is located on the passenger side, second from the front. Always check the connector for looseness; snap-fit connections often fail over time. A simple DITer test involves swapping the coil with a known good one: if the code clears after swapping, the original coil is faulty. If the code remains, the problem may be in the wiring or ignition system.
