P0445 2007 Nissan Sentra Code - EVAP Canister Purge Volume Control Solenoid Valve Circuit Shorted

Quick Answer

The Evaporative Emission System (EVAP) Canister Purge Volume Control Solenoid Valve controls flow rate of fuel vapor from the EVAP canister. Common causes include Faulty Evaporative Emission (EVAP) Purge Solenoid Control, Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted, Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P0445 2007 Nissan Sentra Description

The Evaporative Emission System (EVAP) Canister Purge Volume Control Solenoid Valve controls flow rate of fuel vapor from the EVAP canister. The opening of the vapor by-pass passage in the EVAP canister purge volume control solenoid valve changes to control the flow rate. The EVAP canister purge volume control solenoid valve repeats ON/OFF operation according to the signal sent from the Engine Control Module (ECM). The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapor from the EVAP canister is regulated as the air flow changes.
The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

1. What does the OBDII code P0445 mean on a 2007 Nissan Sentra?

P0445 indicates that there is a short circuit in the EVAP Canister Purge Volume Control Solenoid Valve circuit, which is part of the vehicle's evaporative emissions system.

2. What are common symptoms of code P0445 on a 2007 Nissan Sentra?

Common symptoms include an illuminated check engine light, possible fuel odor near the vehicle, reduced fuel efficiency, and potential difficulty starting the engine.

3. What causes the P0445 code to appear in a 2007 Nissan Sentra?

The most common causes include a shorted or damaged purge volume control solenoid valve, faulty wiring or connectors in the circuit, or issues with the vehicle's powertrain control module (PCM).

4. Can I drive my 2007 Nissan Sentra with a P0445 code?

While the car may still drive, it is not recommended as the emissions system may not function properly, potentially leading to environmental harm and long-term damage to other components.

5. How do I diagnose the P0445 code on a 2007 Nissan Sentra?

Start by inspecting the EVAP purge solenoid valve for damage or corrosion, check the wiring and connectors for shorts or breaks, and use a multimeter to test the solenoid's electrical resistance.

6. How do I fix the P0445 code on a 2007 Nissan Sentra?

Repairs may include replacing the EVAP purge solenoid valve, repairing or replacing damaged wiring or connectors, or, in rare cases, addressing issues with the PCM.

7. What tools are needed to troubleshoot the P0445 code?

You’ll need an OBDII scanner, a multimeter, and possibly basic hand tools to inspect and replace components in the EVAP system.

8. How much does it cost to fix a P0445 code on a 2007 Nissan Sentra?

Repair costs vary but typically range from $50 to $200 for parts and labor, depending on whether the purge solenoid valve or wiring needs replacement.

9. Can a loose gas cap cause a P0445 code on a 2007 Nissan Sentra?

No, a loose gas cap is more likely to trigger a P0442 or P0456 code. Code P0445 specifically points to a short circuit in the EVAP purge solenoid valve.

10. How can I prevent the P0445 code from recurring on my 2007 Nissan Sentra?
