What is the P0352 Fault code? What does it all mean?
The ignition coil supplies high voltage to the spark plugs that ignite the air-fuel mixture. The check engine light will come on if the code P0352 is set. This indicates that there may be a problem in the cylinder 2 circuit or ignition coil. The fault code’s last number indicates which cylinder is suffering from an ignition problem.
The most popular ignition system in modern cars is the COP (coil-on-plug) or plug–in coil ignition system. Each cylinder is controlled by a different coil. The coil is located just above the sparkplug, so there are no spark plug wires. Each coil has two wires. One wire is used for power distribution, and the other is for battery supply. The coil control circuit comes from the PCM. This ground circuit allows the PCM to turn on or off the coil.
The ignition coil acts as a transformer, converting low voltage to high potential. Spark plugs are required to convert low voltage provided by the battery into high voltage. This is necessary for successful fuel combustion. A coil can produce 70,000 to 100,000 volts in average.
An ignition coil usually consists of two coils: a primary and secondary coil. The larger primary coil receives the initial voltage from the batteries and transfers it to a smaller secondary coil. The secondary coil is located within the primary coil. It rotates at high speeds and creates a magnetic field. This creates a magnetic field that helps to infuse the fuel with the high voltage and amperage necessary for ignition.
A code P0352 could occur if the PCM detects an ignition coil problem. As we mentioned above, it is possible for the PCM to detect a problem with the ignition coil. In such cases, the ignition coil should be checked on cylinder 2. The PCM may also switch off the fuel injector depending on the vehicle.
What causes the P0352 Fault code?
There may be many reasons that code P0352 might be stored in a vehicle. To make the right repairs, it is essential to determine the cause. There are many possible causes.
- – Defective cylinder #2 ignition coil
- – Issues with the ignition coil circuit, such as damaged wires or loose connections.
- – Damage to or corrosion of the wiring connecting ignition coil to PCM
- – Defective spark plug(s)
- – Defective PCM
What are the symptoms for P0352 Malfunction Codes?
A P0352 code is when you have all of the symptoms listed above while driving your vehicle. This trouble code should be fixed immediately to prevent more serious problems.
- – Illumination for the check engine light
- – Irregular engine cranking
- – Feeling unusual vibrations when driving or idling
- Engine misfires
- – Dropping during acceleration
How to Fix the P0352 Fault Code
First, conduct a resistance test on the suspect ignition coil. The current voltage should also need to be measured. It is important to check the condition of spark plug electrodes. By wriggling the wires, you can check the condition of the ignition coil for cylinder 2. Start by repairing the cables if wiggling the cables resolves the issue. Verify that there are no loose connections at the coil connector.
- Repair or replacement of damaged coil cable
- – Replacing your ignition coil
- – Replacing spark plugs
- – Repairing vacuum leaks, such as cracked vacuum lines or a leaky intake gasket
- – Replacing engine control module
How serious is the P0352 Fault code?
P0352 is a serious fault code and should not be ignored. A misfiring engine can cause other cylinders work twice as hard. This will cause strain to other cylinders, increasing wear on piston rings, spark plugs, and other ignition coils. It is important to fix the problem quickly. This can also cause damage to the catalytic converter, clogs and further engine damage.
