1. Producte acabatview
The ACDelco GM Original Equipment D580 (12558948) Ignition Coil is a critical component in your vehicle's ignition system. It transforms the battery's low voltage into the thousands of volts required to create an electric spark in the spark plugs, igniting the fuel-air mixture in the engine's cylinders. This process is essential for starting and running the engine efficiently.

5. Principis de funcionament
The ignition coil operates by using electromagnetic induction to generate high voltage. When the engine's computer (ECM) sends a signal, current flows through the coil's primary winding, creating a magnetic field. When the current is interrupted, the magnetic field collapses, inducing a much higher voltage in the secondary winding. This high voltage is then sent to the spark plug, creating the spark necessary for combustion. A properly functioning ignition coil ensures consistent spark delivery, contributing to smooth engine operation, optimal fuel efficiency, and reduced emissions.
6. Manteniment
Ignition coils are generally maintenance-free components. However, regular inspection of your vehicle's ignition system can help identify potential issues early:
- Inspect Spark Plugs: Replace spark plugs according to your vehicle manufacturer's recommendations. Worn spark plugs can put additional strain on ignition coils.
- Comproveu les connexions elèctriques: Periodically inspect the electrical connectors to the ignition coils for corrosion or looseness.
- Monitor Engine Performance: Pay attention to any changes in engine performance, such as misfires, rough idle, or decreased fuel economy, which could indicate an issue with an ignition coil.
7. Solució De Problemes
If you experience issues with your vehicle's ignition system, consider the following common symptoms and potential solutions:
| Símptoma | Causa possible | Solució |
|---|---|---|
| Engine Misfire / Rough Idle | Faulty ignition coil, worn spark plug, or wiring issue. | Inspect and test ignition coils and spark plugs. Replace as needed. Check wiring for damage. |
| Check Engine Light (CEL) | Diagnostic Trouble Code (DTC) related to ignition system. | Scan for DTCs using an OBD-II scanner. Address the specific code. |
| Disminució del consum de combustible | Inefficient combustion due to weak spark. | Ensure all ignition components (coils, plugs) are functioning correctly. |
| Inici difícil | Insufficient spark to ignite fuel. | Check battery, starter, and ignition system components. |
For persistent issues, it is recommended to seek assistance from a certified automotive technician.
