P0445 2002 Nissan Altima Sedan 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 2002 Nissan Altima Sedan Description
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.
What are the Possible Causes of the DTC P0445 2002 Nissan Altima Sedan?
- 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

4. Can I drive my 2002 Nissan Altima with a P0445 code?
While the car may still be drivable, driving with a P0445 code is not recommended as it can lead to increased emissions and potential damage to the EVAP system over time.
5. How do I fix the P0445 code?
Repairs typically involve inspecting and replacing the purge volume control solenoid valve if faulty, repairing or replacing damaged wiring or connectors, and clearing the code with an OBDII scanner.
6. How do I test the purge volume control solenoid valve?
You can test the purge valve with a multimeter to check for proper resistance and functionality. Refer to your vehicle's repair manual for specific testing procedures.
7. What tools are needed to diagnose a P0445 code?
Tools may include an OBDII scanner, a multimeter, and basic hand tools for inspecting and replacing components.
