P2310 Dodge Code - Ignition Coil 'D' 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 'D', Ignition Coil 'D' harness is open or shorted, Ignition Coil 'D' 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 P2310 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 P2310 code sets when the PCM detects a short to voltage in the circuit.

Frequently Asked Questions about P2310 Dodge Code

What does the OBD-II code P2310 mean on a Dodge vehicle?

P2310 indicates an issue with the Ignition Coil 'D' Primary Control Circuit being too high, meaning the power or signal to the coil is outside the expected range.

What are the common symptoms of the P2310 code on a Dodge?

Symptoms may include engine misfires, rough idling, reduced power, poor fuel economy, and an illuminated check engine light.

What causes the P2310 code to appear?

Common causes include a faulty ignition coil, damaged wiring or connectors in the ignition coil circuit, a malfunctioning powertrain control module (PCM), or excessive resistance in the circuit.

Can I drive my Dodge with the P2310 code?

It’s not recommended to drive with this code active, as it can lead to engine misfires, potential damage to the catalytic converter, and reduced performance.

How do I diagnose the P2310 code?

Diagnosis involves inspecting the ignition coil and its wiring for damage, testing the resistance of the coil, checking the circuit for continuity, and using a scan tool to monitor PCM signals.

What tools do I need to fix the P2310 code?

You may need a multimeter, an OBD-II scan tool, and basic hand tools to inspect and repair the ignition coil circuit.

How much does it cost to fix the P2310 code?

Repair costs can vary but typically include the price of a replacement ignition coil ($50-$150) or wiring repair, with additional labor costs if done professionally.

Can a bad PCM cause the P2310 code?

Yes, while less common, a malfunctioning PCM can fail to properly control the ignition coil circuit, triggering the P2310 code.

How do I prevent the P2310 code from reoccurring?

Regular maintenance, including inspecting ignition coils and wiring for wear or damage, and addressing engine issues promptly can help prevent this code.

Does the P2310 code always mean the ignition coil is bad?

No, the issue could also stem from damaged wiring, corroded connectors, or a problem with the PCM, so a thorough diagnosis is essential before replacing parts.
