P0352 2007 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 2007 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 2007 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)
How to Fix the DTC P0352 2007 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.

1. What does the OBDII code P0352 mean on a 2007 Toyota Camry?
P0352 indicates a malfunction in the ignition coil 2 primary or secondary circuit, meaning there’s an issue with the electrical signal or performance of the second ignition coil.
2. What are the common symptoms of code P0352 on a Toyota Camry?
The most common symptoms include engine misfires, rough idling, poor acceleration, reduced fuel efficiency, and an illuminated check engine light.
3. What causes the P0352 code to trigger on a 2007 Toyota Camry?
Common causes include a faulty ignition coil, damaged wiring or connectors in the ignition coil circuit, a bad spark plug, or a malfunctioning engine control module (ECM).
4. Can I drive my 2007 Toyota Camry with the P0352 code?
Driving with a P0352 code is not recommended, as it can cause engine misfires that may lead to poor performance, increased emissions, and potential engine damage over time.
5. How do I diagnose the P0352 code on a Toyota Camry?
Diagnosis involves checking the ignition coil 2 for proper functionality, inspecting the circuit wiring and connectors for damage, testing the spark plug, and using a multimeter to verify the signal from the ECM.
6. How do I fix the P0352 code on my 2007 Toyota Camry?
Repairs typically include replacing the faulty ignition coil, repairing or replacing damaged wiring or connectors, replacing the spark plug, or reprogramming or replacing the ECM if necessary.
7. Can a bad spark plug cause the P0352 code?
Yes, a bad spark plug associated with ignition coil 2 can cause the code, as it may interfere with the ignition coil’s performance and trigger a circuit malfunction.
8. How much does it cost to fix the P0352 code on a Toyota Camry?
The cost depends on the repair needed. Replacing an ignition coil can cost $100–$300, while wiring or ECM repairs may cost more, depending on labor and parts.
9. Can a P0352 code cause long-term damage to my engine?
If left unresolved, the misfires caused by P0352 can lead to unburned fuel entering the catalytic converter, potentially damaging it and causing expensive repairs.
10. Will clearing the P0352 code with a scanner fix the problem?
Clearing the code may temporarily turn off the check engine light, but it won’t fix the underlying issue. The problem causing the code must be repaired to prevent it from returning.
