Code P0351 2016 Chevrolet Silverado Description
The P0351 diagnostic trouble code (DTC) specifically refers to a problem with the ignition coil 1 control circuit in a 2016 Chevrolet Silverado. The ignition coil is a crucial component of the ignition system that is responsible for converting the low voltage from the battery into the high voltage needed to ignite the air-fuel mixture in the combustion chambers. In this case, the control circuit for ignition coil 1 is experiencing issues, which can result in misfires, poor engine performance, and potentially even engine damage if left unresolved.
Common Causes of P0351 2016 Chevrolet Silverado
- Faulty ignition coil: The ignition coil itself may be defective, causing the control circuit to malfunction.
- Damaged wiring or connectors: Corrosion, abrasion, or loose connections in the wiring harness or connectors can disrupt the flow of electricity to the ignition coil.
- ECM issues: A malfunctioning engine control module can send incorrect signals to the ignition coil, resulting in control circuit problems.
- Spark plug issues: Worn out or fouled spark plugs can cause excessive resistance in the ignition system, leading to ignition coil control circuit faults.
- Environmental factors: Moisture, heat, or vibration can also contribute to the deterioration of the ignition coil control circuit over time.
Symptoms of P0351 2016 Chevrolet Silverado
- Check engine light: The most common symptom associated with the P0351 code is the illumination of the check engine light on the dashboard.
- Engine misfires: A misfiring engine, especially in cylinder 1, can result in rough idling, hesitation, and a noticeable decrease in power.
- Poor fuel efficiency: A faulty ignition coil control circuit can lead to incomplete combustion, resulting in decreased fuel efficiency and potentially higher emissions.
- Engine stalling: In severe cases, the engine may stall or have difficulty starting due to a lack of spark in cylinder 1.
- Increased emissions: A malfunctioning ignition coil control circuit can cause unburned fuel to pass through the exhaust system, leading to increased emissions.
How to Fix P0351 2016 Chevrolet Silverado
- Diagnose the issue: Use a scan tool to retrieve the DTC and inspect the ignition coil, wiring, and connectors for any visible damage.
- Replace the ignition coil: If the ignition coil is found to be faulty, replace it with a new one that meets the manufacturer's specifications.
- Repair wiring or connectors: Repair or replace any damaged wiring or connectors in the ignition coil control circuit to ensure proper electrical connections.
- Clear the DTC: After completing the repair, clear the DTC with a scan tool and test drive the vehicle to ensure that the issue has been resolved.
- Perform a final inspection: Verify that the check engine light remains off and that the engine is running smoothly without any misfires or performance issues.
Cost to Fix P0351 2016 Chevrolet Silverado
The typical repair costs for addressing a P0351 code on a 2016 Chevrolet Silverado can range from $150 to $300, including parts and labor. However, it's essential to note that the specific diagnosis time and labor rates at auto repair shops can vary significantly based on factors such as location, vehicle make and model, and engine type. Rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less. Therefore, it's advisable to check local rates for a more precise estimate before proceeding with the repair.
