P2326 Chrysler Code - Ignition Coil 'I' Secondary Circuit

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 'I', Ignition Coil 'I' harness is open or shorted, Ignition Coil 'I' 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: P2326 Chrysler indicates Ignition Coil 'I' Secondary Circuit.
Common causes: Common causes include Faulty Ignition Coil 'I', Ignition Coil 'I' harness is open or shorted, Ignition Coil 'I' 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 P2326 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 P2326 code sets when the PCM detects a short to voltage in the circuit.

Frequently Asked Questions about P2326 Chrysler Code

1. What does the OBDII code P2326 mean on a Chrysler?

P2326 indicates an issue with the Ignition Coil 'I' Secondary Circuit, which is responsible for delivering the necessary spark to the engine's cylinder for combustion.

2. What are the common symptoms of a P2326 code in a Chrysler vehicle?

Symptoms may include engine misfires, rough idling, poor acceleration, reduced fuel efficiency, and the Check Engine Light being illuminated.

3. What causes the P2326 code to appear in a Chrysler?

Common causes include a faulty ignition coil, damaged wiring or connectors in the coil circuit, a bad spark plug, or issues with the Powertrain Control Module (PCM).

4. Which ignition coil is referred to by 'Ignition Coil I'?

The specific coil labeled 'I' depends on your engine's cylinder configuration and firing order. Refer to your vehicle's service manual for the exact location.

5. Can a bad spark plug cause the P2326 code?

Yes, a worn or damaged spark plug can increase resistance in the circuit, leading to the P2326 code being triggered.

6. How do you diagnose the P2326 code on a Chrysler?

Diagnosis involves using a scan tool to confirm the code, inspecting the ignition coil 'I' and its wiring, checking spark plug condition, and testing the coil with a multimeter.

7. Can you drive a Chrysler with the P2326 code?

Driving with this code is not recommended, as it can cause engine misfires and potentially lead to further damage, such as catalytic converter failure.

8. How do you fix the P2326 code in a Chrysler?

Repairs may involve replacing the faulty ignition coil, repairing damaged wiring or connectors, replacing spark plugs, or reprogramming or replacing the PCM if needed.

9. How much does it cost to repair the P2326 code on a Chrysler?

The cost varies, but replacing an ignition coil typically ranges from $150 to $300, while spark plug replacement is generally $100 to $200. Labor costs depend on the repair shop rates.

10. Can a failing PCM cause the P2326 code?

Yes, a malfunctioning PCM can misinterpret data or fail to control the ignition coil properly, leading to this code. However, this is less common and should be checked after ruling out other causes.
