Hyundai Code P0355 is a diagnostic trouble code that is related to an ignition coil ‘E’ circuit malfunction. This code is triggered when the Powertrain Control Module (PCM) detects an unexpected voltage condition on the ignition coil ‘E’ primary circuit. The ignition coil must function properly to keep an engine running, and the PCM is responsible for monitoring the voltage condition. If a malfunction is detected, the PCM will generate this code. Understanding the potential causes and solutions of Hyundai Code P0355 is important for a successful repair.

Causes and Solutions of Hyundai Code P0355
| Cause | Solution |
|---|---|
| Ignition Coil ‘E’ primary circuit is open or shorted to ground | Repair or replace the Ignition Coil ‘E’ primary circuit |
| The ignition Coil ‘E’ power circuit is open (test power from I/P fuse) | Repair or replace the Ignition Coil ‘E’ power circuit |
| Ignition Coil ‘E’ is damaged or has failed | Replace the Ignition Coil ‘E’ |
| PCM has failed | Replace the PCM |
Ignition Coil ‘E’ Primary Circuit
The primary circuit of the Ignition Coil ‘E’ is responsible for providing the spark energy to the spark plug. When the PCM detects an unexpected voltage condition on the primary circuit, it will generate this code. To diagnose this issue, the technician must inspect the wiring and connectors for any signs of corrosion or damage. If any damage is found, the circuit must be repaired or replaced.
Ignition Coil ‘E’ Power Circuit
The Ignition Coil ‘E’ ‘s power circuit provides the coil’s power. If the power circuit is open, the technician must inspect the wiring and connectors for any signs of corrosion or damage. If any damage is found, the course must be repaired or replaced. The technician will also need to test the power from the I/P fuse to ensure that the administration is reaching the coil.

FAQs About Hyundai Code P0355
What does the engine code P0355 signify?
The Diagnostic Trouble Code (DTC) P0355 denotes “Ignition Coil “E” Primary/Secondary Circuit.” This means that the PCM has observed a malfunction in either the primary (which is the computer’s side) or the secondary (which is the spark plug’s side) circuit of the #5 ignition coil, commonly referred to as “E.”
What does the term “ignition coil primary/secondary circuit” mean?
DTC P0351, which relates to “Ignition Coil ‘A’ Primary/Secondary Circuit,” signifies that there might be an issue with the primary or secondary winding of the ignition coil for cylinder #1. Each ignition coil possesses a primary winding and a secondary winding. The primary winding generates a magnetic field when current flows through it, and the secondary winding releases this energy to the spark plug, leading to ignition.
Where can you find the ignition coil B?
Ignition coil B, or the coil for the second cylinder, is situated above the double cylinder of your vehicle’s engine. In essence, if a malfunction is associated with the ignition coil B, it implies an issue with the ignition process in the second cylinder. Remember that the location of the ignition coils may vary depending on the engine design and model of the vehicle. It’s always beneficial to consult the vehicle’s manual or a repair guide for precise information.
