P2306 Chrysler Code - Ignition Coil 'C' Primary Control Circuit Low

Quick Answer

The P2306 Chrysler diagnostic trouble code (DTC) refers to an issue with the ignition coil 'C' primary control circuit being low. Common causes include Faulty ignition coil: A malfunctioning ignition coil can cause the primary control circuit voltage to drop below the expected levels, Wiring issues: Damaged or corroded wiring connections between the ignition coil and the ECM can disrupt the flow of voltage in the primary circuit, ECM malfunction: A problem with the Engine Control Module (ECM) could also be the cause of the low voltage in the ignition coil 'C' primary control circuit. 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 P2306 Chrysler Description

The P2306 Chrysler diagnostic trouble code (DTC) refers to an issue with the ignition coil 'C' primary control circuit being low. This code is typically triggered when the Engine Control Module (ECM) detects a lower than expected voltage in the primary circuit of ignition coil 'C'. In a vehicle's ignition system, the ignition coil is responsible for converting the low voltage from the battery into a high voltage needed to create a spark in the spark plugs. This spark is crucial for igniting the air-fuel mixture in the engine cylinders, allowing the vehicle to run smoothly.

Common Causes of P2306 Chrysler

  1. Faulty ignition coil: A malfunctioning ignition coil can cause the primary control circuit voltage to drop below the expected levels.
  2. Wiring issues: Damaged or corroded wiring connections between the ignition coil and the ECM can disrupt the flow of voltage in the primary circuit.
  3. ECM malfunction: A problem with the Engine Control Module (ECM) could also be the cause of the low voltage in the ignition coil 'C' primary control circuit.
  4. Poor electrical connection: Loose or poor electrical connections can lead to voltage drops in the ignition system, triggering this code.

Symptoms of P2306 Chrysler

  1. Engine misfires: The most common symptom associated with this code is engine misfires, where the vehicle may experience jerking or hesitation during acceleration.
  2. Rough idle: A rough or unstable idle can occur when the ignition coil 'C' primary control circuit is low, causing the engine to run erratically.
  3. Decreased fuel efficiency: When the ignition system is not functioning properly, fuel may not be burned efficiently, leading to decreased fuel economy.
  4. Illuminated check engine light: The ECM will typically trigger the check engine light when it detects a problem with the ignition coil 'C' primary control circuit.

How to Fix P2306 Chrysler

  1. Diagnose the issue: Use a scan tool to read the DTC and diagnose the specific cause of the low voltage in the ignition coil 'C' primary control circuit.
  2. Inspect wiring and connections: Check for any damaged or corroded wiring connections between the ignition coil and the ECM, repairing or replacing as needed.
  3. Test the ignition coil: Test the ignition coil to determine if it is functioning correctly. Replace the ignition coil if it is found to be faulty.
  4. Check the ECM: If no other issues are found, consider checking the ECM for any malfunctions that may be causing the low voltage in the primary circuit.
  5. Clear the DTC: After completing the repairs, clear the DTC and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P2306 Chrysler

The typical repair costs for addressing the P2306 Chrysler code can vary depending on the specific cause of the issue. In general, replacing a faulty ignition coil can cost between $100 and $250, including parts and labor. If wiring repairs or ECM diagnostics are needed, additional costs may apply. It's important to note that diagnosis time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate based on your vehicle make and model.
