Code P0444 2006 Infiniti G35 Description
The P0444 diagnostic trouble code (DTC) for a 2006 Infiniti G35 indicates a problem with the EVAP (Evaporative Emission Control) system. Specifically, it points to an issue with the EVAP Canister Purge Volume Control Solenoid Valve circuit being open. The EVAP system is designed to capture and store fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. The canister purge valve is responsible for controlling the flow of fuel vapor from the charcoal canister to the engine intake manifold.
Common Causes of P0444 2006 Infiniti G35
- Faulty EVAP Canister Purge Volume Control Solenoid Valve: The valve itself may be defective and require replacement.
- Wiring Issues: Damaged or corroded wiring connecting the solenoid valve to the PCM can cause an open circuit.
- Blown Fuse: A blown fuse in the EVAP system circuit can prevent the solenoid valve from receiving power.
- PCM Malfunction: A malfunctioning PCM may not be sending the proper signals to the solenoid valve, resulting in an open circuit.
Symptoms of P0444 2006 Infiniti G35
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: A malfunctioning EVAP Canister Purge Volume Control Solenoid Valve can lead to a rough or unstable idle when the vehicle is at a standstill.
- Decreased Fuel Efficiency: Since the EVAP system plays a role in fuel vapor management, a fault in this system can result in decreased fuel efficiency.
- Hissing Noise: In some cases, a hissing noise may be audible from the engine compartment, indicating a leak in the EVAP system.
How to Fix P0444 2006 Infiniti G35
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform further diagnostics to identify the exact cause of the open circuit.
