P0352 2009 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 2009 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 2009 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)

Frequently Asked Questions about P0352 2009 Toyota Camry Code
1. What does the OBDII code P0352 mean on a 2009 Toyota Camry?
P0352 indicates a malfunction in the ignition coil circuit for cylinder 2, affecting either the primary or secondary circuit.
2. What are the common symptoms of code P0352 on a 2009 Toyota Camry?
Symptoms may include engine misfires, rough idle, reduced power, poor fuel economy, and the check engine light turning on.
3. What causes the P0352 code in a 2009 Toyota Camry?
Common causes include a faulty ignition coil, damaged wiring or connectors in the ignition coil circuit, or a malfunctioning powertrain control module (PCM).
4. How do I diagnose the P0352 code on a 2009 Toyota Camry?
Start by inspecting the ignition coil for cylinder 2, checking for visible damage or corrosion on wiring and connectors. Use a multimeter to test resistance and continuity, and swap ignition coils to see if the problem moves to another cylinder.
5. Can a bad spark plug cause the P0352 code in a 2009 Toyota Camry?
No, a bad spark plug itself won’t directly trigger P0352, but it may contribute to misfires that can be mistaken for ignition coil issues.
6. How can I fix the P0352 code on my 2009 Toyota Camry?
Repairs typically involve replacing the faulty ignition coil, repairing or replacing damaged wiring or connectors, or, in rare cases, reprogramming or replacing the PCM.
7. Can I drive my 2009 Toyota Camry with a P0352 code?
Driving with this code is not recommended as it can lead to further engine damage, increased emissions, and unsafe driving conditions due to misfires.
8. How much does it cost to fix the P0352 code on a 2009 Toyota Camry?
The cost varies, but replacing an ignition coil typically ranges from $150 to $300, including parts and labor. Wiring repairs or PCM replacement may cost more.
9. Is it safe to clear the P0352 code without fixing the issue?
Clearing the code without addressing the problem will not resolve the underlying issue and may result in the code returning or further engine damage.
10. Can a bad battery cause the P0352 code on a 2009 Toyota Camry?
While unlikely, low voltage from a weak battery can cause electrical issues that might affect ignition coil operation, so the battery should be tested as part of the diagnosis.
