Code P3404 2017 GMC Sierra Description
The P3404 diagnostic trouble code (DTC) for a 2017 GMC Sierra specifically refers to an issue with the Cylinder 1 Deactivation Solenoid Valve Control Circuit registering high voltage. In vehicles equipped with cylinder deactivation technology, such as GM's Active Fuel Management (AFM) system, certain cylinders can be deactivated during light load conditions to improve fuel efficiency. The solenoid valve controls the flow of oil to deactivate the cylinders, and if the control circuit detects high voltage, it indicates a problem with the solenoid valve's operation.
Common Causes of P3404 2017 GMC Sierra
- Faulty cylinder 1 deactivation solenoid valve
- Wiring issues in the control circuit
- Defective engine control module (ECM)
- Poor electrical connections
- Corrosion or damage to the solenoid valve
Symptoms of P3404 2017 GMC Sierra
- Rough idling
- Engine misfires
- Reduced engine power
- Decreased fuel efficiency
- Illumination of the Check Engine Light
How to Fix P3404 2017 GMC Sierra
- Begin by conducting a thorough inspection of the cylinder 1 deactivation solenoid valve and its wiring harness to check for any visible damage or corrosion.
- Test the solenoid valve using a multimeter to determine if it is functioning within the manufacturer's specified parameters.
- Inspect the wiring harness for any breaks, shorts, or loose connections that could be causing the high voltage issue.
- If the solenoid valve and wiring are in good condition, test the ECM to ensure it is sending the correct signals to the solenoid valve.
- Replace any faulty components, such as the solenoid valve, wiring harness, or ECM, as needed to resolve the high voltage in the control circuit.
Cost to Fix P3404 2017 GMC Sierra
The typical repair costs for addressing a P3404 DTC on a 2017 GMC Sierra can vary depending on the specific cause of the issue. In general, replacing a faulty solenoid valve or repairing wiring issues may cost between $200 to $500, including parts and labor. If the ECM needs to be replaced, the total repair cost could range from $500 to $1000 or more. It's important to note that diagnosis time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate based on your location and vehicle specifics.
