Code P0445 2006 Infiniti G35 Description
The P0445 code for a 2006 Infiniti G35 indicates a problem with the EVAP (Evaporative Emission Control System) Canister Purge Volume Control Solenoid Valve Circuit being shorted. This valve is responsible for controlling the flow of vapors from the fuel tank to the engine intake manifold. When the engine is running, the EVAP system captures and stores fuel vapors to prevent them from escaping into the atmosphere. The Purge Volume Control Solenoid Valve regulates the amount of fuel vapor that is purged into the engine for combustion.
Common Causes of P0445 2006 Infiniti G35
- Faulty Purge Volume Control Solenoid Valve: The valve itself may be defective and causing the circuit to short.
- Wiring Issues: Damaged or corroded wiring connections can lead to a short in the circuit.
- ECM (Engine Control Module) Failure: A malfunctioning ECM can also trigger the P0445 code.
- Vacuum Leaks: Any leaks in the EVAP system can disrupt the proper functioning of the Purge Volume Control Solenoid Valve.
Symptoms of P0445 2006 Infiniti G35
- Check Engine Light: The most common symptom associated with the P0445 code is the illumination of the check engine light on the dashboard.
- Rough Idle: A malfunctioning Purge Volume Control Solenoid Valve can cause irregular engine idle or stalling.
- Decreased Fuel Efficiency: Since the EVAP system plays a role in fuel vapor management, a faulty valve can lead to decreased fuel efficiency.
- Strong Fuel Odor: If the fuel vapors are not properly controlled and purged, you may notice a strong smell of gasoline around the vehicle.
How to Fix P0445 2006 Infiniti G35
- Diagnose the Issue: Use a scan tool to confirm the P0445 code and perform further testing to pinpoint the exact cause of the circuit short.
- Inspect Wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test Purge Volume Control Solenoid Valve: Test the valve itself to ensure it is functioning correctly. Replace if necessary.
- Clear Codes: After repairing the issue, clear the diagnostic trouble codes from the vehicle's ECM to reset the check engine light.
- Retest: After repairs are completed, perform a final test drive to ensure the issue has been resolved and the check engine light does not reappear.
Cost to Fix P0445 2006 Infiniti G35
