P0356 2010 Toyota Camry Code - Ignition Coil 6 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 6, Ignition Coil 6 harness is open or shorted, Ignition Coil 6 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 P0356 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.

- Faulty Ignition Coil 6

Driving with this code is not recommended, as engine misfires can cause further damage to the catalytic converter and other components.
5. How do I diagnose the P0356 code on a 2010 Toyota Camry?
Diagnose the issue by checking ignition coil 6, inspecting its wiring and connectors for damage, and testing the coil with a multimeter to confirm functionality.
6. How do I fix the P0356 code on a Toyota Camry?
Fixes may include replacing the faulty ignition coil, repairing damaged wiring, replacing worn spark plugs, or reprogramming/updating the ECM if needed.
7. Which ignition coil is cylinder 6 on a 2010 Toyota Camry?
Cylinder 6 is located on the back bank of the engine (closer to the firewall) and is the third cylinder from the passenger side.
