Code P2316 2014 GMC Sierra Description
The diagnostic trouble code P2316 for a 2014 GMC Sierra refers to an issue with the ignition coil 6 control circuit having high voltage. In an internal combustion engine, the ignition coil is responsible for converting the battery's low voltage into the high voltage needed to ignite the air-fuel mixture in the combustion chamber. The ignition coil control circuit ensures that the ignition coil fires at the correct time to spark the spark plug, leading to combustion.
Common Causes of P2316 2014 GMC Sierra
- Faulty wiring in the ignition coil control circuit
- Malfunctioning ignition coil
- Damaged spark plug
- Issues with the engine control module
- Corrosion or loose connections in the electrical system
Symptoms of P2316 2014 GMC Sierra
- Engine misfires
- Rough idling
- Poor acceleration
- Decreased fuel efficiency
- Engine stalling
How to Fix P2316 2014 GMC Sierra
- Begin by conducting a visual inspection of the ignition coil 6 control circuit and surrounding components to check for any obvious signs of damage or issues.
- Test the ignition coil with a multimeter to determine if it is functioning correctly. Replace the ignition coil if necessary.
- Inspect the spark plug connected to ignition coil 6 for any signs of damage or wear. Replace the spark plug if needed.
- Check the wiring in the ignition coil control circuit for any breaks, corrosion, or loose connections. Repair or replace wiring as needed.
- If the issue persists, diagnose the engine control module for any faults or malfunctions and replace if necessary.
Cost to Fix P2316 2014 GMC Sierra
