What vehicles are most commonly affected by P0355?
Commonly affected models include the 2000-2015 Honda Accord, 2000-2018 Toyota Camry, and various models of the Nissan Altima from 2002-2015. Always check for any recalls or technical service bulletins related to ignition issues.
How can I prevent P0355 from happening again?
Regular maintenance checks, including inspecting wiring and connections, can help prevent P0355. Replacing spark plugs and ignition coils at recommended intervals can also reduce the chance of recurrence.
What is P0355?
DTC P0355 refers to a malfunction in the ignition coil 'E' primary/secondary circuit. This code is commonly seen in various vehicles, particularly in Honda and Toyota models from around 2000 to 2018. The ignition coil is essential for generating the high voltage needed to ignite the fuel-air mixture in the engine's cylinders. When this code is triggered, it indicates that the Engine Control Module (ECM) has detected a problem with the ignition coil circuit for Cylinder 5 (or 'E'). This could be due to various issues such as a faulty ignition coil, damaged wiring, or poor connections. In practical terms, if your vehicle is displaying this code, you may experience symptoms like rough idling, misfires, or a decrease in engine performance. Ignoring this issue can lead to worsening symptoms and potential engine damage, so it's crucial to address it promptly. Moreover, the check engine light will typically illuminate, alerting you to the problem. In some cases, you might notice a decrease in fuel efficiency or a hesitation during acceleration, which can impact your overall driving experience.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0355 is present:
- Check engine light stays on constantly, indicating a problem that needs attention.
- Engine hesitates during acceleration, which can make driving feel unsafe and unpredictable.
- Fuel economy decreased by 10-15%, leading to more frequent trips to the gas station.
- Rough idling that causes the vehicle to shake or vibrate when at a standstill.
- Increased exhaust emissions, which can contribute to environmental issues and potential fines.
Possible Causes
Most common causes of P0355 (ordered by frequency):
- Faulty ignition coil is the most common cause, accounting for about 60% of cases. A failed coil can prevent the engine from firing properly, leading to misfires.
- Damaged wiring or poor connections, which can occur due to wear and tear or rodents chewing on wires. This issue may lead to intermittent performance problems.
- Corroded connectors or terminals can prevent proper electrical flow, often due to moisture intrusion. Regular inspections can help prevent these issues.
- ECM malfunction is less common but can lead to misdiagnosis. It's essential to ensure the ECM is functioning correctly before replacing components.
- Faulty spark plugs can also lead to ignition issues. If the spark plugs are worn, they may not provide a strong enough spark, compounding the problem.
