P0358 - Ignition Coil H Primary/Secondary Circuit

2014 Ford Focus Titanium, 4D Hatchback, Automatic DCT Trans, Gas/EthanolSECTION P0358 - Ignition Coil H Primary/Secondary Circuit
P0358 - IGNITION COIL H PRIMARY/SECONDARY CIRCUIT

Description:  This DTC sets when the PCM does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the ignition module PCM.
Possible Causes: 
  • VPWR circuit open
  • VPWR circuit short to ground
  • COP8 circuit open
  • COP8 circuit short to voltage
  • COP8 circuit short to ground
  • Damaged COP
Diagnostic Aids:  The DTC P0358 only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not set the DTC P0358. The DTC P0308 does not set for a coil primary circuit malfunction. The DTC P0358 may set with or without the DTC P0308, however the DTC P0358 sets first.
When this DTC is set, the PCM enters failure mode effects management (FMEM) which shuts down the injector for the associated cylinder in order to protect the catalytic converter. This is normal operation, do not attempt to diagnose the injector with this DTC present.
If a primary coil is damaged due to a harness short to ground the PCM will not be damaged. Do not replace the PCM without verifying the coil driver functionality.
Use the 12-volt non-powered test lamp to verify VPWR voltage at the ignition coil harness connector.
Check the coil driver circuit for open, short to voltage, or short to ground.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
