Laymans terms

This means that the car's computer detected a problem with the electrical signal going to one of the ignition coils. It's like if a light bulb isn't getting the right amount of power to turn on.

Explanation

The engine control module (ECM) has detected a high voltage condition in the primary control circuit of the ignition coil labeled 'G'.

Technical description

The P2319 code is triggered when the ECM detects a voltage level that is higher than expected in the primary control circuit for ignition coil G. This could be due to a short circuit, faulty ignition coil, or issues with the wiring or connectors.

Symptoms

• Check Engine Light is on

• Engine misfires

• Poor engine performance

Common Causes

• Faulty ignition coil G

• Short circuit in the ignition coil wiring

• Poor electrical connection in the ignition coil circuit
