P2307 Chrysler Code - Ignition Coil 'C' Primary Control Circuit High

Quick Answer

The current flow, or dwell, through the primary ignition coil is controlled by the Powertrain Control Module (PCM) by providing a switched ground path through the ignition coil driver to ground. Common causes include Faulty Ignition Coil 'C', Ignition Coil 'C' harness is open or shorted, Ignition Coil 'C' 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.

What it means: P2307 Chrysler indicates Ignition Coil 'C' Primary Control Circuit High.
Common causes: Common causes include Faulty Ignition Coil 'C', Ignition Coil 'C' harness is open or shorted, Ignition Coil 'C' circuit poor electrical connection.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2307 Chrysler Description

The current flow, or dwell, through the primary ignition coil is controlled by the Powertrain Control Module (PCM) by providing a switched ground path through the ignition coil driver to ground. When the ignition coil driver is switched on, current rapidly builds up to a maximum value, determined by the coil inductance and resistance. When the current is switched off, the magnetic field collapses which induces a secondary high voltage surge and the spark plug is fired. This high voltage surge creates a flyback voltage which the PCM uses as a feedback during the ignition diagnostics. The PCM continuously monitors the ignition system for concerns. The P2307 code sets when the PCM detects a short to voltage in the circuit.

Common symptoms include engine misfires, rough idling, loss of power, and illuminated Check Engine Light.

2. What causes the OBDII code P2307 Chrysler to trigger?

The code is triggered when the Engine Control Module (ECM) detects a high voltage condition in the primary control circuit of ignition coil 'C'.

3. How can I diagnose the cause of OBDII code P2307 Chrysler?

Diagnose by checking the wiring and connections related to ignition coil 'C', testing the ignition coil itself, and inspecting the ECM for any faults.

4. Can a faulty ignition coil be the cause of OBDII code P2307 Chrysler?

Yes, a faulty ignition coil for cylinder 'C' can cause the primary control circuit to have a high voltage condition, triggering the code.

5. What are the repair options for OBDII code P2307 Chrysler?

Repair options include replacing the faulty ignition coil 'C', repairing any damaged wiring or connections, and resetting the ECM to clear the code.

6. Is it safe to continue driving with OBDII code P2307 Chrysler present?

It is not recommended to continue driving with the code present, as it can lead to further engine damage and decreased performance.

7. How do I reset the Check Engine Light after repairing OBDII code P2307 Chrysler?

The Check Engine Light can be reset using an OBDII scanner or by disconnecting the car's battery for a few minutes.

8. Can a DIY enthusiast repair OBDII code P2307 Chrysler at home?

DIY enthusiasts with the necessary tools and knowledge can attempt to diagnose and repair the code at home, but professional help may be needed for complex issues.
