P2335 Dodge Code - Ignition Coil 'L' 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 'L', Ignition Coil 'L' harness is open or shorted, Ignition Coil 'L' 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.

Code P2335 Dodge 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 P2335 code sets when the PCM detects a short to voltage in the circuit.

Frequently Asked Questions about P2335 Dodge Code

What does the OBDII code P2335 mean for Dodge vehicles?

P2335 indicates an issue with the ignition coil 'L' secondary circuit. This error suggests that the coil is not functioning as expected, which can affect engine performance.

What are the common symptoms of code P2335 in Dodge vehicles?

Symptoms include engine misfires, rough idling, reduced power, poor fuel economy, and the Check Engine Light being illuminated.

What causes the P2335 code to appear?

Common causes include a faulty ignition coil 'L', damaged wiring or connectors in the circuit, a malfunctioning powertrain control module (PCM), or excessive carbon buildup on the spark plug.

How can I diagnose the P2335 code on my Dodge?

Start by inspecting the ignition coil 'L' and its wiring for damage or corrosion. Use a multimeter to test the coil's resistance and verify the circuit's continuity. Check the spark plug condition and look for PCM-related issues.

Can I still drive my Dodge with the P2335 code active?

Driving with this code is not recommended as it can lead to engine misfires, reduced performance, and potential damage to other components like the catalytic converter.

How do I fix the P2335 code on a Dodge?

Repairs may include replacing the ignition coil 'L', repairing or replacing damaged wiring or connectors, cleaning or replacing the spark plug, or reprogramming or replacing the PCM if necessary.

How much does it cost to repair code P2335 on a Dodge vehicle?

Repair costs vary but typically range from $100 to $300 for ignition coil replacement, plus labor charges. If PCM repair or reprogramming is needed, costs may increase significantly.

Can a dirty or damaged spark plug cause the P2335 code?

Yes, excessive carbon buildup or damage to the spark plug associated with ignition coil 'L' can trigger the P2335 code by disrupting the secondary circuit.

How can I prevent the P2335 code from occurring in the future?

Regular maintenance, including timely replacement of spark plugs, inspection of ignition coils, and ensuring wiring and connections are secure, can help prevent this code.

Does the P2335 code affect fuel efficiency in Dodge vehicles?

Yes, the P2335 code can reduce fuel efficiency due to engine misfires and suboptimal combustion caused by ignition circuit issues.
