P0352 2006 Toyota Camry Code - Ignition Coil 2 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 2, Ignition Coil 2 harness is open or shorted, Ignition Coil 2 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 P0352 2006 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 P0352 2006 Toyota Camry?
- Faulty Ignition Coil 2
- Ignition Coil 2 harness is open or shorted
- Ignition Coil 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
