Code P0443 2007 Nissan Pathfinder Description
The EVAP canister purge volume control solenoid valve uses an 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.
The Diagnostic Trouble Code (DTC) will set when the canister purge flow is detected during the specified driving conditions, even when the EVAP canister purge volume control solenoid valve is completely closed.
What are the Possible Causes of the DTC P0443 2007 Nissan Pathfinder?
- Faulty EVAP Canister Purge Volume Control Solenoid Valve
- EVAP Canister Purge Volume Control Solenoid Valve harness is open or shorted
- EVAP Canister Purge Volume Control Solenoid Valve circuit poor electrical connection
- Faulty EVAP Control System Pressure Sensor
How to Fix the DTC P0443 2007 Nissan Pathfinder?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0443 2007 Nissan Pathfinder Code
1. What does the OBDII code P0443 mean on a 2007 Nissan Pathfinder?
P0443 indicates a malfunction in the EVAP Canister Purge Volume Control Solenoid Valve circuit, which is part of the vehicle’s evaporative emissions control system.
2. What are the symptoms of code P0443 on a 2007 Nissan Pathfinder?
Common symptoms include the check engine light turning on, possible fuel odor, and a slight decrease in fuel efficiency. However, drivability issues are rare.
3. What causes the P0443 code on a 2007 Nissan Pathfinder?
This code is typically caused by a faulty purge volume control solenoid valve, damaged wiring or connectors, or issues with the EVAP system's electrical circuit.
4. How do I fix the P0443 code on my 2007 Nissan Pathfinder?
Start by inspecting the wiring and connectors to the purge solenoid for damage or corrosion. Replace the solenoid if it's faulty, and clear the code with an OBDII scanner to see if it returns.
5. Is it safe to drive with a P0443 code on my 2007 Nissan Pathfinder?
Yes, driving with a P0443 code is generally safe, but prolonged neglect can lead to increased emissions or damage to other components of the EVAP system.
6. How do I test the EVAP Canister Purge Volume Control Solenoid Valve for P0443?
Use a multimeter to check the solenoid's resistance, which should match the specifications in the vehicle's service manual. You can also apply a 12V power source to verify proper operation.
7. Can a loose gas cap cause a P0443 code on a 2007 Nissan Pathfinder?
No, a loose gas cap typically triggers a different code (P0455 or P0442). P0443 specifically relates to the purge volume control solenoid valve circuit.
8. How much does it cost to fix a P0443 code on a 2007 Nissan Pathfinder?
Repair costs vary but generally range from $100 to $300, depending on whether you replace the solenoid yourself or have a mechanic perform the repair.
9. Can a faulty purge volume control solenoid valve affect fuel economy?
Yes, a malfunctioning solenoid can lead to a slight decrease in fuel efficiency due to improper EVAP system operation.
10. Will clearing the P0443 code without repairs fix the issue?
No, clearing the code will only temporarily turn off the check engine light. If the underlying issue isn’t resolved, the code will likely reappear.
