Code P2315 2017 GMC Sierra Description
The P2315 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates an issue with the ignition coil 6 control circuit experiencing low voltage. The ignition coil is a crucial component in the vehicle's ignition system responsible for converting the low-voltage power from the battery into the high-voltage power needed to ignite the fuel in the engine cylinders. When the control circuit for ignition coil 6 is receiving lower than expected voltage, it can lead to misfires, rough idle, poor acceleration, and overall decreased engine performance.
Common Causes of P2315 2017 GMC Sierra
- Faulty wiring or connectors in the ignition coil control circuit
- Defective ignition coil
- Malfunctioning Engine Control Module (ECM)
- Issues with the power supply to the ignition coil
- Electrical interference or shorts in the circuit
Symptoms of P2315 2017 GMC Sierra
- Engine misfires or rough idle
- Decreased fuel efficiency
- Lack of power or acceleration
- Illumination of the Check Engine Light
- Engine stalling or hesitation
How to Fix P2315 2017 GMC Sierra
- Perform a diagnostic scan to confirm the P2315 code and identify the specific ignition coil 6 control circuit issue.
- Inspect the wiring and connectors in the ignition coil control circuit for any damage, corrosion, or loose connections.
- Test the ignition coil for proper operation using a multimeter to check for resistance and voltage output.
- Check the power supply to the ignition coil to ensure it is within the manufacturer's specified range.
- Replace the faulty ignition coil, repair any damaged wiring or connectors, and clear the DTC from the vehicle's ECM.
Cost to Fix P2315 2017 GMC Sierra
The typical repair costs for addressing an ignition coil 6 control circuit low voltage issue can range from $150 to $300, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's advisable to check local rates for a more precise estimate. Keep in mind that rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less.
