“Primary/Secondary Circuit Malfunction in Ignition Coil C” defines the P0353 error-detecting code (DTC).

A malfunction with igniting circuit C, or the coil network, is indicated by this OBD-II generic diagnostic code. Combustion coil C is positioned on engine cylinder #3 and is coil number 3.

A general DTC signals the same problem for any car with an OBD-II engine, but exact repair instructions may vary depending on the car’s model number. Your specialist may have to consult the vehicle’s maintenance handbook and wiring diagram to undertake fixes.

P0353 Code Meaning

If the engine control module or powertrain control module detects a problem with the igniting circuit or coil connection for cylinder #3, the P0353 warning is generated. The coil circuit’s main (PCM) or second (spark plug) sides can both have issues.

The ignition coil in most contemporary automotive engines has separate coils of combustion for each cylinder. Each combustion coil in a coil pack is monitored and controlled by the PCM’s combustion controller.

P0353 Code Meaning:

Based on which igniter has a malfunction, the PCM will assign the error P0351 to P0362 if it doesn’t accurately detect indications from the coil pack connection.

The last digit of the error specifies which cylinders have a faulty coil.

P0351 represents cylinder #1 (ignite coil A), P0353 represents cylinder #3 (combustion circuit C), and onwards. Code P0362 for V12 engines denotes a circuit unit problem in cylinder #12 (ignition system L).

OBD-II Code P0353 : Symptoms, Causes & Diagnose


Although the P0353 code is generally a code for the ignition system, it can be caused by various engine problems.

These include:

  • An ignition coil that isn’t working properly.
  • Coil controller or coil circuit malfunctions
  • Corrosion or destruction to the ignition coil connection
  • An ignition coil that is loose or has a bad network
  • Connection locks that are broken
  • A defective ignition coil or defective combustion system wiring
  • The ignition coil wiring loom has a broken connection.
  • A pressure leakage in the inlet manifold of the engine
  • Carbon accumulation in the air channels Errors in the PCM 


The P0353 code might cause several symptoms.

The following are the most common:

  • The warning light, also known as the Malfunction Indicator Lamp, is illuminated
  • Having trouble igniting the car
  • Engine misfires on a regular or irregular basis.
  • An engine rest that is harsh or unpredictable
  • Vibrations that are unusual when the vehicle is resting or running
  • Lack of speed – the motor lacks energy, particularly when loaded heavily.

The OBD-II system may stop the fuel injector on the defective cylinder in some automobiles. Other fault codes linked to the motor firing or injector unit difficulties may also appear.

It’s important to remember that some symptoms, such as an illuminated Check Engine Light or difficulties starting the vehicle, can be caused by various reasons. These can range from a braking boost pressure leak to difficulties with the ignition system.

The PCM may enter “limp mode” to protect the motor or transmissions from further damage in more extreme circumstances.

What is the severity of the P0353 error code?

It all depends on how severe the problems are.

  • Some could result in driveability concerns, such as difficulty starting the automobile due to a faulty coil. You’ll almost certainly need to hire a car expert in this instance.
  • A harsh idle caused by an engine malfunction is unlikely to deter you from taking your car to the workshop, but keeping it neglected will result in additional motor damage.
  • The catalytic converter may get blocked or destroyed due to an engine malfunction, forcing the motor cylinders to function much harder. All involved parts, including the combustion system, coil packing, and piston rings, are put under more stress.
  • A defective PCM, albeit uncommon, could pose several safety risks.
  • To summarize, a P0353 error will most likely not prevent you from running your car but should be addressed as soon as possible.

How to diagnose P0523 OBD-II Code

Your expert uses an OBD scanner to check the codes recorded in the PCM to begin troubleshooting. Next, To check whether they can duplicate the problem, they’ll clear the signals and test the drive with identical settings.

Identifying the origin of the P0353 ignition coil C error code can’t be easy and will necessitate using various tools, such as a multimeter and a testing light.

The car specialist will do the following:

  • Determine whether the motor malfunction is permanent or temporary.
  • Look for any damaged, rusted, or broken elements in the coil pack, coil connection, and cabling.
  • Inspect the combustion system & its wiring.
  • Remember To check the coil controller circuit’s voltage.
  • Check the coil control circuitry for electrical connection (ohms).
  • Inspect the camshaft and the crank sensor for damages.
  • If no other problems are found, check the engine controller.
  • P0353 is a code that should be properly examined. The code can reappear if you skip diagnostic stages and replace parts before testing them. A basic element like a twisted connection pin or a loosened wire, for example, can nonetheless cause ignition coil problems.

How to fix P0523 obd2 code

Depending on what prompted code P0355, the sorts of replacement and repair may vary.

How to fix

The following are examples of possible repairs:

  • combustion coil C replacement
  • The coil pack, cabling, and connections must all be replaced.
  • Ignition system and igniter cable replacement
  • Fixing or repairing the C connection on an ignition system
  • Any additional electrical cabling or coil connections issues will be repaired.
  • Putting a stop to the pressure leak
  • Maintenance or replacement of the PCM

As you’ll see from the above list, fixes can vary in complexity.

So, what’s the best way to fix code P0353? A Simple Answer to the P0353 Error is to ensure the P0353 code goes away for good; you’ll need a reliable professional to diagnose it and perform extensive repairs.

It is better if they’re car professionals who can come to your home and do repairs right away. This will spare you the problem of running a car to a mechanic with a problem.

Final Thoughts

While the P0353 code indicates a problem with ignition coil C, the possible causes are numerous and vary in severity.

As a result, it’s always a good idea to entrust any engine troubles to a professional, whether as simple as a loose connector or as complicated as a PCM circuit problem.
