P2319 Fault Code

Ignition Coil G Primary Control Circuit High

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2319 code indicates an issue with the ignition coil G primary control circuit being high. This means that the Engine Control Module (ECM) has detected a voltage level that exceeds the expected range for ignition coil G. Typically, this relates to the electrical systems involved in controlling the ignition timing and spark generation necessary for engine combustion.

What are the symptoms of the P2319 code?

• Check Engine Light illuminated on the dashboard.
• Engine misfire during operation.
• Rough idling or unstable engine performance.
• Decrease in fuel efficiency due to inefficient combustion.
• Difficulty starting the engine or prolonged cranking time.

What causes the P2319 code?

• Faulty ignition coil G.
• Short circuit in the wiring or connectors of the ignition coil.
• Open circuit or high resistance in the ignition coil circuit.
• Problems with the Engine Control Module (ECM).
• Poor ground connection or faulty ground wiring.
• Issues with other ignition system components, like the spark plugs or other coils.

How to fix P2319?

• Inspect and replace the faulty ignition coil G.
• Check all wiring and connectors for shorts or breaks, and repair as necessary.
• Test the ECM for proper operation and reprogram or replace if faulty.
• Verify ground connections and repair or replace any damaged wires.
• Conduct a thorough inspection of the ignition system, including spark plugs and related components.
