The check engine light on a 2004 Chevrolet Silverado 1500 may illuminate due to various reasons such as a loose gas cap, faulty O2 sensor, catalytic converter issue, or a bad spark plug. These issues can range from simple and inexpensive to complex and costly to fix. For instance, tightening or replacing a gas cap typically costs between $15 and $30. However, replacing a catalytic converter could set you back anywhere from $1,500 to $1,540.
If the "check engine light" pops up on your 2004 Chevy Silverado, it could be due to a loose gas cap or a more critical problem such as a faulty o2 sensor, a significant emissions leak, or issues with the catalytic converter in your vehicle.
