Code P2319 2016 GMC Sierra Description
The diagnostic trouble code P2319 for a 2016 GMC Sierra indicates a problem with the ignition coil 7 control circuit, specifically detecting high voltage. The ignition coil is a crucial component in the vehicle's ignition system, responsible for converting the low voltage from the battery into the high voltage needed to create a spark in the spark plugs. When the ignition coil control circuit shows high voltage, it means that there is an issue with the electrical signal being sent to the ignition coil, potentially leading to misfires, rough idling, and overall poor engine performance.
Common Causes of P2319 2016 GMC Sierra
- Faulty ignition coil.
- Damaged wiring or connectors in the ignition coil circuit.
- Issues with the engine control module (ECM).
- Corrosion or poor connections in the ignition system.
- Electrical interference or short circuits.
Symptoms of P2319 2016 GMC Sierra
- Engine misfires or hesitation during acceleration.
- Rough idling or stalling.
- Decreased fuel efficiency.
- Illumination of the check engine light.
- Engine vibration or shaking.
How to Fix P2319 2016 GMC Sierra
- Begin by diagnosing the specific cause of the high voltage in the ignition coil control circuit using a diagnostic scanner.
- Inspect the ignition coil, wiring, and connectors for any visible damage or corrosion.
- Test the ignition coil and related components for proper functionality using a multimeter.
- Replace the faulty ignition coil, repair any damaged wiring or connectors, and clear the trouble code from the ECM.
- Perform a test drive to ensure that the issue has been resolved and that the vehicle is running smoothly.
Cost to Fix P2319 2016 GMC Sierra
