OBD-II Generic Error Code P2319: How to Fix It

Q: What does ignition coil G primary control high mean?

It means the engine control module detected a voltage higher than expected in the primary circuit of ignition coil G. This can be caused by a shorted coil, wiring issues, or a faulty ECM.

Q: Can I drive with error code P2319?

It is not recommended. The misfire can cause poor performance, reduced fuel economy, catalytic converter damage, and increased emissions. Drive only to a repair shop.

Q: Is P2319 a generic or manufacturer-specific code?

P2319 is a generic powertrain code. However, the specific coil assignment (which cylinder is 'G') can vary by manufacturer. Check your repair manual.

Q: How much does it cost to fix P2319?

If you DIY, a replacement ignition coil costs $50-$150. Professional repair (including diagnosis and labor) can range from $200-$400.

Q: Do I need to replace the spark plugs too?

Not necessarily. But it's good practice to inspect spark plugs for wear. If they are old or damaged, replace them along with the coil.

Abstract

Error code P2319 means the engine control module (ECM) has detected a high voltage condition in the primary circuit of ignition coil G. This often points to a faulty coil, wiring issue, or a failing ECM. Ignition system faults can cause misfires, rough running, and increased emissions.
