P0355 2010 Toyota Camry Code - Ignition Coil 5 Primary/Secondary Circuit
Quick Answer
The DIS is a 1-cylinder ignition system in which each cylinder is ignited by one ignition coil and one spark plug is connected to the end of each secondary wiring. Common causes include Faulty Ignition Coil 5, Ignition Coil 5 harness is open or shorted, Ignition Coil 5 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0355 2010 Toyota Camry Description
The ECM determines the ignition timing and transmits the ignition (IGT) signals to each cylinder. Using the IGT signal, the ECM turns the power transistor inside the igniter on and off. The power transistor, in turn, switches on and off the current to the primary coil. When the current to the primary coil is cut off, a powerful voltage is generated in the secondary coil. This voltage is applied to the spark plugs, causing them to spark inside the cylinders. As the ECM cuts the current to the primary coil, the igniter sends back an ignition confirmation (IGF) signal to the ECM, for each cylinder ignition.
What are the Possible Causes of the DTC P0355 2010 Toyota Camry?
- Faulty Ignition Coil 5
- Ignition Coil 5 harness is open or shorted
- Ignition Coil 5 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0355 2010 Toyota Camry?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0355 2010 Toyota Camry Code
1. What does the OBDII code P0355 mean on a 2010 Toyota Camry?
P0355 indicates a malfunction in the ignition coil "5" primary or secondary circuit, which may affect the vehicle's ignition performance.
2. What are the common symptoms of code P0355?
Symptoms include engine misfires, rough idling, reduced fuel efficiency, hesitation during acceleration, and the check engine light being illuminated.
3. What causes the P0355 code to appear?
The code can be triggered by a faulty ignition coil, damaged wiring or connectors in the coil 5 circuit, a failed spark plug, or a malfunctioning Engine Control Module (ECM).
4. How do I locate ignition coil 5 on a 2010 Toyota Camry?
In a 2010 Toyota Camry with a 4-cylinder engine, ignition coil 5 isn't applicable. For the V6 engine, ignition coil 5 is typically the fifth coil when counting from the front of the engine.
5. Can I drive my 2010 Toyota Camry with a P0355 code?
Driving with a P0355 code is not recommended, as it can lead to further engine damage, reduced performance, and increased fuel consumption.
6. How do I fix the P0355 code on my Toyota Camry?
Common fixes include replacing the faulty ignition coil, repairing or replacing damaged wiring, inspecting and replacing the spark plug, or, in rare cases, reprogramming or replacing the ECM.
7. How do I diagnose the P0355 code?
Diagnosis typically involves using an OBDII scanner, checking the ignition coil and its circuit for damage, testing continuity, and inspecting the spark plug for wear.
8. How much does it cost to fix the P0355 code on a 2010 Toyota Camry?
The repair cost varies but typically ranges from $100 to $300, depending on whether the issue is a faulty ignition coil, wiring repair, or spark plug replacement.
9. Can a bad spark plug cause the P0355 code?
Yes, a worn or damaged spark plug can cause ignition coil 5 to malfunction, triggering the P0355 code.
10. Can a faulty ECM cause the P0355 code?
While rare, a malfunctioning ECM can cause the P0355 code by failing to properly control the ignition coil 5 circuit.
