Order of inspection
P0354 Ignition Coil D Primary/Secondary Circuit High
The P0354 code means the computer found a fault in the circuit of ignition coil D, which normally belongs to cylinder 4. It is usually accompanied by a misfire in that cylinder. A cylinder with no spark can overheat the catalytic converter, so do not put off the repair.
