What Does This Mean P0358 Ignition Coil H Primary/Secondary Circuit Malfunction.

Posted in Ignition Systems | Asked on Dec 30, 2010

I got this code off my 1997 ford E350 (triton V10 6.8L) this van uses (COP) coil on plug for the ignition system.
Which cylinder number is this code for? if i am looking at the engine from inside the cab which cyl. is it? I think that it is the second cylinder on the drivers side from inside the cab that is causing the problem.

    The Check Engine Light (CEL) is on and there is a code P0358

    Tests/Procedures: 1. Code P0358 is for cylinder #8.

    2. Inspect the spark plug, coil, and coil boot on that cylinder for signs of damage. Replace as needed.

    3. If no problems are found with the components, check the wiring harness from the coil to the Powertrain Control Module (PCM).

    Potential Causes: Failed coil or boot
    Failed spark plug
    Harness problem
