What is the P0302 Code?
The P0302 code is a diagnostic trouble code (DTC) that indicates a misfire in cylinder 2 of your engine. When the Engine Control Module (ECM) detects that the engine is not firing properly in this cylinder, it triggers the P0302 code.
Common Causes of P0302 Code
Several factors can lead to a P0302 code in your Chevrolet Silverado 1500. Here are some of the most common causes:
- Faulty Spark Plug: A worn or damaged spark plug can cause a misfire in the cylinder.
- Ignition Coil Issues: If the ignition coil for cylinder 2 is malfunctioning, it can lead to a misfire.
- Fuel Injector Problems: A clogged or faulty fuel injector can prevent the proper amount of fuel from reaching the cylinder.
- Vacuum Leaks: Leaks in the intake manifold or vacuum hoses can disrupt the air-fuel mixture.
- Engine Mechanical Issues: Problems such as low compression or a damaged valve can also cause misfires.
Symptoms of P0302 Code
When your Silverado 1500 triggers the P0302 code, you may notice several symptoms, including:
- Rough Idling: The engine may shake or vibrate while idling.
